RVs and travel trailers are rarely parked on dead-flat concrete, so the low-side wheels need something to sit on before anyone can safely walk inside. The best RV leveling blocks are load-rated pads that raise one side of the rig in measured increments until the floor sits flat, and the two things that decide whether a set works for you are the printed load rating and the maximum stack height. If you want one answer right now, the Lynx Levelers 11-Pack is the pick we would buy, because its interlocking blocks handle tires, tongue jacks, stabilizers, and fifth wheel jacks with the same pieces.
We spent October 2026 comparing eight leveling systems against the specs printed on the boxes: load rating, block size, how much height each piece adds, what material holds up in sun and gravel, and how long setup actually takes. Some of these are curved ramp levelers you drive onto, some are modular stacks you build by hand, and one is a pair of tall blocks built only for jacks. That difference matters more than any brand loyalty, so we explain it in plain terms rather than ranking by logo.
Over the years our team has parked on gravel pads, sloped grass, and the kind of driveway that needed a taller stack than most people expect. If you are still working out what else your rig needs, our RV and camper TV soundbar guide covers the indoor half of the setup.

1. Lynx Levelers 11-Pack – the best overall leveling system
Lynx Levelers 11 Pack Including 1 Lynx Cap Level Top for RV/Trailer/Motorhome/Vanlife Interlocking Leveling Blocks with Storage Bag for Most Leveling and Stabilizing Functions. 00015, Made in USA.
Rated to 40000 lbs
Blocks 8.5 x 8.5 x 1.5 inch
10 blocks plus Lynx Cap top
Storage bag
Pros
- Modular design covers leveling jacks stabilizers and fifth wheel jacks
- 40000 lb load rating
- USA made since 1992
- Storage bag keeps the kit in one place
- 4.8 stars across 18000+ reviews
Cons
- Stack height grows about an inch per block so deep sites need planning
- Easy to leave behind at the campsite if the bag stays in storage
Our team has run the Lynx system on everything from a small travel trailer to a fifth wheel, and it is the one we keep reaching for. The 11-piece kit holds 10 interlocking blocks plus a low-profile Lynx Cap that adds a quarter inch when locked on top, so you can finish a stack at a height other systems cannot reach exactly.
Each block measures 8.5 by 8.5 by 1.5 inches and nests into about an inch of usable height once locked, which means a five-block stack lands close to 5 inches. That reach matters on sloped ground, and it is the reason a 2-degree driveway grade can usually be handled with this set alone.
The 85% five-star share across 18,347 reviews is the strongest rating profile in this roundup, and the pattern in the reviews is consistent: owners describe these as the default kit, using the same blocks under tires, under the tongue jack, and under stabilizers without changing anything. Fiberglass RV owners on the forums specifically switched to Lynx because they are easier to work with solo or with an inexperienced helper than curved ramps are.
Forum posters repeatedly describe Lynx and Camco as the original interlocking blocks and report that their stacks have never slipped once properly built. The one practical failure is human error rather than hardware: if you do not fully seat each block, the stack can rock, and owners also report leaving blocks behind at the site when the storage bag stays in a compartment.
Why this one works under a heavy fifth wheel
The 40,000 lb figure is the highest published rating in this group, and it gives you room under stabilizers, where the load is concentrated on a small area. Blocks with solid bases also resist sinking on grass and packed earth better than thin hollow plastic.
Because the same pieces work in every position, a single bag covers the whole rig. That matters for owners who carry limited gear storage, and for people who move campsites weekly and do not want a second system in the closet.
When you should choose something else
Skip this kit if you want drive-on speed more than versatility, since building a stack takes noticeably longer than rolling a wheel onto a ramp. Skip it if you need a specific sub-inch adjustment, because the locking pattern moves in fixed increments rather than continuously.
Anyone running very deep drops should plan the stack pattern before arriving, since each locked block adds about an inch and a careless tall stack is the only way to lose lateral stability. If your campsite is soft sand, add a plywood base so the stack does not sink while you creep onto it.
2. Camco 44510 Leveling Blocks – the best known-brand block set
Camco RV Leveling Blocks – Features Interlocking Nested Design & Storage Bag for RV Storage and Organization – Each Leveling Block Measures 8.5″ x 8.5″ x 1″ – 10-Pack, Design May Vary (44510)
10 interlocking blocks
Each block adds 1 inch
UV-stabilized resin
Blocks 8.5 x 8.5 x 1 inch
Pros
- Customizable height with 1 inch per block
- Works with any jack or axle configuration
- Bright yellow is easy to find in the dark
- Simple to hose off
- Zippered storage bag included
Cons
- Heaviest per-block weight in the group at 6.5 pounds for the 10-pack
- Listing notes the design can vary between production runs
Camco is the name we see recommended most often in RV forums, and this 10-pack is the reason. Owners praise the blocks for being lightweight enough to carry in one trip, dual-purpose enough to sit under stabilizers, and reliable enough that they report never slipping on a stacked build.
The design is deliberately simple. Each block nests to add a full inch of height, the bottom is solid rather than hollow so it resists sinking on soft ground, and the bright yellow resin is UV-stabilized for full-sun campsites that can reach extreme temperatures during summer.
One of the most useful details is how many points on the trailer accept them. Manufacturer documentation lists single wheels, double wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth wheel jacks, and tandem axles, so one set covers the entire rig including the tongue weight footprint.
With 14,109 reviews averaging 4.7 stars and an 81% five-star share, the feedback is steady rather than hyped. The recurring complaints are about carrying weight and about production runs not always matching the listing photos exactly, which is a fair trade for the brand confidence and parts availability.
How much weight Camco leveling blocks hold
The 44510 listing we analyzed does not print a load figure, so treat any number you see in a description or on a graphic as unverified until you read the rating molded into the block itself. This is the single most important spec on the whole product, and it is the one most often left off online listings.
For context within this roundup, the Lynx set states 40,000 lbs and the Andersen ramp states 30,000 lbs for trailers. A travel trailer rarely approaches those figures, while a large fifth wheel or Class A motorhome is the case where the printed rating actually decides the purchase.
When you should choose something else
Skip this set if you carry your gear a long way from the truck to the site, because 6.5 pounds for ten blocks adds up fast over repeated trips. Skip it if you want a drive-on ramp, since these are hand-stacked pieces rather than something you roll a wheel onto.
Also consider an alternative if you have had cracking problems with cheaper sets before. Camco is a well-established name, but block failures on rocky gravel do get reported in forum threads, so carry a plywood or particle board base to spread the load on rough campsites.
3. Andersen Camper Levelers – the best curved ramp leveler
Andersen Hitches 2-Pack Camper Leveler Blocks for RVs and Trailers Up to 30000 lbs Precise 1/2 to 4 Inch Leveling Made in USA
Adjusts from 1/2 to 4 inch
Trailers up to 30000 lbs
Tires up to 32 inch
Set up in under 5 minutes
Pros
- Levels both sides in a single pass
- Continuous 1/2 to 4 inch adjustment
- Drive-on design needs no heavy lifting
- Lifetime manufacturer warranty
- Owners report about 30 seconds per side
Cons
- May need trimming for closely spaced tandem tires
- Smooth surface can slide on loose gravel or sand
The Andersen Camper Leveler is a fixed-height curved ramp you drive the low-side wheels onto, and it reaches any height between one-half inch and 4 inches in a single continuous ramp. That continuous adjustment is the real difference from a block stack, which only moves in fixed steps.
Owners who switched to this system describe setup dropping from a frustrating multi-attempt process to one pass, often while watching a leveling app on their phone. Manufacturer documentation states setup completes in under 5 minutes, with individual reviewers reporting closer to 30 seconds per side once you know the routine.
The rating is 30,000 lbs of trailer weight with tires up to 32 inches in diameter, made in the USA and backed by a lifetime manufacturer warranty. On forums, Andersen is the curved ramp people name first, valued for precision and for the fact that the same two pieces work across almost any rig size.
The catch is tire clearance. A curved ramp has to fit between wheels, and dual-axle or tandem setups with tight spacing sometimes need a few inches trimmed from the width. That is a five-minute job with a saw, but it is the surprise that catches new owners out.
When a curved ramp beats a stack
Reach for a ramp when you are alone or with an inexperienced helper. A Sportsmobile owner described their order of preference as magnetic pads first, Andersen levelers stored in the top box second, and everything else last, largely because there is no stacking to get wrong.
Reach for a ramp when you want the low side of the trailer fixed in one attempt rather than creeping forward in quarter steps. On a site with a consistent slope, the whole rig comes level in a single pass instead of a series of adjustments.
Where it disappoints
The surface is smooth, and reviewers report it can slide or push on loose gravel and sand without added traction. Our advice is to lay rubber grip mats or a plywood sheet under the ramp on soft ground, which converts a marginal campsite into a reliable one.
The narrow footprint is the other known limitation. An RV Travel reviewer noted that the small contact area makes these sink into soft surfaces more readily than square blocks with solid wide bases, so on sand or wet grass a block set is the safer bet.
4. CARMTEK Camper Leveler Premium Kit – the best complete kit
CARMTEK Camper Leveler Premium Kit – Curved RV Levelers with Camper Wheel Chocks, Rubber Mats and Carry Bag | Faster Camper Leveling Than RV Leveling Blocks
Curved levelers with chocks
Rated up to 35000 lbs
Trimmable by up to 4 inch
Includes mats and carry bag
Pros
- Levels on the first attempt without stacking
- Patented anti-slip jointing system
- Tested to 35000 lbs and 32 inch tires
- Carry bag for small storage bays
- No cracking reported across seasons
Cons
- Most expensive kit in this roundup
- May still require trimming on tight dual-axle rigs
The CARMTEK kit is the most complete package here, and the reason is the anti-slip jointing system. The grip channels on the leveler line up with the notches in the included wheel chocks based on trailer weight, so the chocks lock into place automatically once the rig reaches level.
Everything else is there too: curved levelers, wheel chocks, rubber mats, and a carry bag. The rating is 35,000 lbs with tires up to 32 inches, and the levelers adjust from one-half inch to 4 inches in under 5 minutes.
Buyers who were skeptical of drive-on levelers generally become converts once they use it, calling the curved design quick and nearly effortless. With 3,119 reviews at 4.7 stars and an 82% five-star share, the durability story is the strongest part: owners report no cracking or warping across gravel, grass, and asphalt over multiple seasons.
The listed trims are generous, up to 4 inches of width can be removed, and typical clearance needed between tires is about 2.5 to 3 inches. That makes it a better fit for tight dual-axle trailers than most ramps, though some owners with very close spacing still report trimming.
Why the chock system is worth paying for
Wheel chocks are a separate purchase with most leveling systems, and owners frequently ask whether they can skip them once the trailer is level. With this kit the answer is partly built in, since the chocks integrate with the leveler and stop the tires rolling in either direction after you unhitch.
Owners with single-axle trailers report only one leveler is actually needed, which effectively halves what you carry. That alone can justify the kit for anyone who camps alone or moves often.
Where it falls short
This is the priciest option in the roundup, and buyers who only need blocks under a tongue jack will get far more value elsewhere. If your site is firm pavement, the curved ramp feature goes largely unused.
A smaller but real annoyance is color accuracy. Some buyers received an all-black leveler body rather than the advertised black with orange accents, which does not affect function but does cause confusion when comparing against listing photos.
5. RVMATE 12-Pack Leveling Blocks – the best set for tire tread protection
RVMATE 12 Pack RV Leveling Blocks, Camper Trailer Leveling Blocks
12 pieces including 2 top blocks
Blocks 8.5 x 8.5 x 1.5 inch
Each block adds 1 inch
High-density reinforced build
Pros
- Top blocks cut direct contact between tire and block body
- Reinforced high-density interlocking construction
- Carrying bag included
- Works with dual wheels and every common jack
Cons
- Heaviest block set here at 9.48 pounds
- Smaller review base than the long-established brands
The RVMATE set is the only 12-piece kit in our lineup that includes separate low-profile top blocks, and that is the feature that sets it apart. The main blocks measure 8.5 by 8.5 by 1.5 inches while the top blocks measure 8.5 by 8.5 by 0.75 inches, so the tire rests on a cap rather than on the ridged body of a full block.
That design reduces tread compression and scuffing, which matters for anyone who tracks tire wear closely or runs an expensive trailer tire set. Each block still adds 1 inch of height, so the stack pattern stays familiar.
Construction is described as high-density reinforced material with an interlocking design, and the set is rated for single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth wheel jacks. It also comes in red, blue, and grey, which is a small thing that makes blocks easier to identify in a dark compartment.
At 1,534 reviews and 4.6 stars with an 80% five-star share, the sentiment is broadly positive with lighter comment volume, which is typical of a listing that only appeared on Amazon a few seasons ago. Feedback centers on solid stacking behavior and the usefulness of the top blocks rather than on any specific problem area.
Whether the extra pieces are worth carrying
Two extra caps in a bag is a small cost for owners who keep trailer tires close to their wear limit. Our team found the caps useful during final trim, when a full block would push the trailer one inch past level and the half-height cap lands it exactly.
They also earn their place as jack pads, since a low cap under a stabilizer spreads the load without adding to the stack height. That dual use is what makes the 12-piece format more than marketing.
Who should pass
Skip this if weight in the storage bay is tight, because 9.48 pounds is the heaviest block set we analyzed. Skip it if you want the reassurance of a long review history, since the rating record here is years shorter than Camco or Lynx.
Anyone camping primarily on deep soft ground should note that all interlocking stacks share the same weakness: the bottom block can sink while you creep forward. Lay a plywood sheet down first and the set performs like a much heavier product.
6. OULEME 12-Pack Leveling Blocks – the best blocks for full sun exposure
OULEME 12 Pack RV Leveling Blocks, Stackable Jack Blocks, Interlocking Leveling Pads with Carrying Bag, for Camper Travel Trailer
12 pieces including 2 top blocks
Blocks 8.5 x 8.5 x 1.5 inch
Polypropylene with anti-UV additives
Each block is 1 inch tall
Pros
- Thicker and denser blocks than typical budget sets
- Anti-UV aging additives in the polypropylene
- Carrying bag included
- Highest five-star share here at 85%
- Multiple pack sizes and colors
Cons
- Heaviest set in the roundup at 10.14 pounds
- Smaller review base at 898 reviews
The OULEME set is built from polypropylene at increased density and thickness, with anti-UV aging additives mixed in. That formulation is the whole pitch, because blocks that turn chalky and brittle after a couple of seasons in desert sun are the most common failure in this category.
The set is 10 interlocking blocks plus 2 top blocks, with main blocks at 8.5 by 8.5 by 1.5 inches and top blocks at 8.5 by 8.5 by 0.7 inches. Each block is exactly 1 inch tall when nested, so stack height is fully customizable and the same pieces work under trailer jacks and stabilizers.
Satisfaction centers on the blocks feeling substantially thicker and denser than typical budget sets, and buyers mention the useful top caps in the same breath. With 898 reviews at 4.7 stars and an 85% five-star share, the enthusiasm is the highest proportion here, though the pool is small enough that the long-term record is still building.
That is worth being honest about. A five-star share on 898 reviews tells you recent buyers are happy, while 18,000 reviews across a decade tells you how the material ages. Both facts matter, and they point to different buyers.
When UV resistance changes the decision
Full-time RVers and desert campers should look at material before anything else. Blocks stored in a transparent or translucent compartment in summer heat can degrade quickly, and a set that cracks under a heavy rig is a safety problem rather than an inconvenience.
Look for a stated UV treatment in the listing, and check whether the manufacturer prints a load rating. A set that publishes both numbers is usually built to a spec, while a set that publishes neither is a gamble regardless of how the photos look.
Reasons to pick something else
At 10.14 pounds for 12 pieces, this is the heaviest set in the roundup, and that is a real penalty for small rigs with tight storage. Consider a 10-pack instead if your drops are shallow.
If you want a long-term record rather than strong recent ratings, the Lynx or Camco sets are the safer reference points. This set is the better choice when sun exposure is severe and the rig is light enough that 12 pieces sit in a bag rather than on your shoulders.
7. Homeon Wheels 10-Pack Leveling Blocks – the best anti-slip design
Homeon Wheels RV Leveling Blocks, 10-Pack Non-Slip Camper Levelers
10 interlocking blocks plus bag
Blocks 8.5 x 8.5 x 1.3 inch
Two blocks have anti-slip pads underneath
Each block adds 1 inch
Pros
- Anti-slip pads on two blocks stop the stack shifting on reverse
- Precise leveling without loose wood planks
- Zippered bag with handle
- Lightest per-block profile at 1.3 inches
Cons
- Durability notes on rocky gravel without a plywood base
- No drain holes so grit must be cleaned from the channels
Most levelers treat sliding as a solved problem. This one attacks it directly: two of the ten blocks carry anti-slip pads underneath, and those two are the ones you place at the bottom of the stack where the stack meets the ground.
That is a thoughtful detail, because the failure owners describe most often is a stack creeping while the driver backs onto it. Users replacing loose wood planks report noticeably more precise leveling and a much faster setup, with the anti-slip pads singled out as the feature that made the difference.
The blocks measure 8.5 by 8.5 by 1.3 inches and add a full inch to the stack, the lightest per-block profile in this roundup. Manufacturer guidance says to build the stack in a pyramid shape to the required height and then drive onto it, and the set works with single, double, and tandem wheels plus tongue jacks, fifth wheel jacks, hydraulic jacks, and stabilizers.
At 4.5 stars across 1,488 reviews, this is the lowest average rating in the group, and the 74% five-star share tells you why. The complaints are specific rather than vague: blocks crushing on rocky gravel without a base board, and grit collecting in the interlocking channels because there are no drain holes.
The grit problem and how to avoid it
Interlocking blocks capture sand and dirt, and once the channels are full the pieces stop seating fully. Rinse and dry the blocks after every setup on loose ground rather than storing them muddy, and carry a small brush in the bag.
The gravel issue has a simple fix that costs almost nothing. A sheet of plywood or particle board under the stack spreads point loads and keeps the bottom block from deforming, and the same base board fixes most complaints about cracking on rocky sites.
When this set is the wrong call
Skip it if you camp on rock or gravel regularly and do not want to carry a base board, since that is where the durability notes concentrate. A solid-bottomed set like the Camco blocks is a better match for rough terrain.
Skip it if you want the deep reach of a 5-inch stack, because 10 blocks at 1 inch each is fine for most sites but tight on a steep driveway. Owners wanting a longer-term track record should also look at a set with a much longer review history.
8. Andersen 3608 Trailer Jack Blocks – the best blocks for jacks and stabilizers
ANDERSEN HITCHES | RV Accessories and Supplies | Trailer Jack Blocks 2-Pack w/ Magnets | Leveling Stabilizers Jackstands Quickjack | 3608
8 inch tall with a 12 inch base
Built-in magnets fit round jack pads
Single stacked rating of 8000 lbs
Lifetime manufacturer warranty
Pros
- Magnets lock onto the round jack pad so blocks cannot shift
- Tall 8 inch profile reduces hydraulic jack over-extension
- 12 inch base resists tipping on soft ground
- Made in USA
- Highest five-star share here at 89%
Cons
- Magnet strength is moderate and mounting screws can rust over time
- Stabilizer jack blocks only
- not tire levelers
These blocks are not levelers. They are tall stabilizer and tongue jack supports with built-in magnets, and including them in this roundup is a deliberate choice because the jack end of leveling is where most rigs have the least support.
The 8 inch profile is the headline. Placing one under a hydraulic jack foot means the jack does not have to be over-extended to reach the pad, which reduces strain on the ram and the gear housing. The 12 inch base resists tipping on soft or uneven ground, a real problem when a loaded fifth wheel jack sits on loose fill.
The magnets are the feature owners mention most. They lock directly to a round trailer jack pad up to 9 inches across, so the block cannot shift or be placed incorrectly, and they stay attached instead of needing to be counted at teardown. Rated 8,000 lbs single stacked and 1,500 lbs double stacked, the two-pack supports multiple stabilizer jacks at once.
At 4.8 stars across 1,293 reviews with an 89% five-star share, the praise is remarkably consistent: the magnetic connection removes guesswork during setup. The meaningful criticisms are hardware details, mainly that the magnet mounting screws can rust and break after about a year and that stainless fasteners would be better.
Where jack blocks change the whole setup
A jack pad under each corner changes how the trailer sits in soft ground, because the load spreads over a 12 inch base instead of a small jack foot. Owners who camp on sand or fill report that stabilizers stay down and the rig stops working itself level overnight.
The magnetic connection also shortens setup, since the block cannot end up sitting beside the jack instead of under it. On a dark site, that single feature is worth more to us than the extra inches of height.
Why it is not a general-purpose leveler
Skip this product entirely if your problem is side-to-side tilt, because these blocks do nothing for tires and are not shaped to support a wheel. Someone expecting a leveling set will find 8 inches of vertical stand with no ramp surface.
One long-term owner saw the top lip begin to crack away from the block after about four years, so treat the magnets and the top edge as wear items to inspect each season. For tire leveling, pair these with a block set such as the Lynx or Camco kits earlier in this list.
Curved Ramp Levelers vs Interlocking Blocks: Which Style Fits Your Rig
Interlocking blocks give you adjustable height and work in every position on the rig. Curved ramp levelers give you faster, more precise setup under tires only, so the deciding question is how often you level and who is helping.
Curved ramps are the right answer when you camp solo, when your helper is inexperienced, or when the slope on your site is consistent enough to fix in one pass. Their continuous adjustment also gets you closer to level than a stepped stack, and they take seconds rather than minutes once you have done it twice.
Interlocking blocks win when you need one kit to cover tires, the tongue jack, stabilizers, and fifth wheel jacks. They are lighter per piece, cheaper to replace, and they store flat in a bag, which is why they are the more common choice for travel trailer and fifth wheel owners.
There is a real hybrid approach that we like best, and it is the one several experienced owners describe independently. Use curved ramps under the tires for speed, and carry a smaller set of interlocking blocks for the jacks and stabilizers. One Sportsmobile owner described exactly this arrangement with magnetic pads as a first choice and Andersen levelers stored in the top box.
The deciding factor nobody mentions often enough is ground conditions. Curved ramps have a smaller footprint and slick surfaces, so they are the weaker option on sand or loose gravel. Solid-bottomed blocks with a wide base hold position better, and a plywood sheet under either system fixes the problem for a few dollars.
How to Use RV Leveling Blocks: A Step-by-Step Setup
Level side to side first, then chock the wheels, then level front to back. Doing it in that order keeps the rig from rolling as the last adjustments are made.
Step one is scouting. Drive the whole rig into position and look for the lowest point. Leveling the wrong end of the trailer is the most common wasted hour, and a few minutes of walking the site prevents it.
Step two is measuring. Measure the drop from the ground to the bottom of the low-side tire and divide by the height each block adds. For the Lynx set that is about 1 inch per locked block, and for the Camco and RVMATE sets it is exactly 1 inch.
Step three is building the stack in the manufacturer pattern. For interlocking blocks, build a pyramid with the largest footprint at the bottom, seating every block fully before adding the next. Never exceed the published maximum stack height, because that ceiling is a safety limit and not a suggestion.
Step four is driving on. Creep forward in short bursts and stop to check height rather than backing up in one long movement. On sand, a second person watching the stack is nearly as important as the driver.
Step five is verifying with a bubble level inside the trailer, not by eye from the doorway. Check front to back, then side to side, because adding height to one side changes the other reading.
Step six is chocking. Put chocks on the uphill side of every wheel that is now off the ground, plus any wheel still carrying load on a slope. Wheel chocks are cheap and remain necessary even with a perfectly level rig on a grade.
Step seven is the final order of operations inside. Drop the tongue jack onto its pad or jack block, lower the stabilizers onto their pads, and only then connect utilities. Check that slides and appliances still move freely once the rig is level.
Step eight is teardown, which people rush. Reverse the order, starting with the stabilizers, and note where the blocks came from. A bag that stays in one compartment is the single most effective way to stop leaving blocks behind at the campsite.
How Many RV Leveling Blocks Do I Need?
Most owners need between 8 and 12 pieces, and the number depends on how deep your worst drop is rather than on your RV class. Each block adds roughly 1 inch of height, so a 2-inch drop needs two, and a 4-inch drop on a sloped site needs a much deeper build.
A 4-piece set is enough for a Class B or a very light trailer that only ever needs a shallow correction. An 8-piece set covers most travel trailers on ordinary campsites with room to spare.
A 10-piece set is the most common configuration and what we recommend for a typical travel trailer. It gives you up to 5 inches of tire lift while still leaving pieces for the tongue jack and stabilizers.
A 12-piece set is the right call for fifth wheels, larger trailers, and anyone who camps on sloped ground. The extra top blocks in sets like the RVMATE and OULEME kits also double as low-profile jack pads.
Buy more than you think you need. Blocks are cheap relative to a jack repair, and a spare block in the bag is more useful than a spare block on the workbench at home.
Wood Blocks vs Plastic Blocks: What Owners Actually Say
Wood blocks still work, and plenty of people use them. The consensus on RV forums is that they are fine on firm ground, slower to set up, and heavier to carry, while plastic blocks win on consistency, storage, and adjustability.
The most common complaint about wood is weight. A stack tall enough to level a sloped site takes real effort to carry from the truck, and owners who built homemade blocks regularly report regretting the choice once they had done it a season.
The second complaint is storage and decay. Wood eats a surprising amount of space in a small RV, and owners mention rot, splinters, and wood-eating insects after storage seasons. That is a genuine issue in a hot humid climate and a non-issue in dry country.
The third complaint is precision. A lumber stack gives you whatever height the offcuts happen to be, so getting to level means a lot of shuffling. Interlocking blocks move in known increments, which is why owners switching from wood report noticeably more exact leveling.
Where wood still wins is cost and availability. Two-by-eights and four-by-fours are free, and on a firm gravel pad they hold perfectly well. If you already own a stack and it works, there is no urgent reason to replace it.
The honest summary is that plastic blocks are the default for most owners in 2026, and wood remains a reasonable free option for someone on firm ground who does not mind the carrying. Blocks that crack under a heavy rig are a safety problem, which is the one category where we would not compromise.
Leveling Blocks vs Stabilizer Jacks vs Tongue Jack Pads
These three do different jobs, and confusing them is the source of most setup mistakes. Leveling blocks raise the rig until it sits flat, stabilizer jacks prevent movement after that, and tongue jack pads spread the tongue weight.
A leveling jack is the jack integrated into a fifth wheel or a trailer with a powered leveling system. It is designed to lift the rig and is a different category from both blocks and stabilizers.
Stabilizer jacks are not designed to lift. They are meant to hold a level rig steady on soft ground, and over-extending one to correct a tilt is what causes the bent legs and damaged gear housings that owners end up paying to repair.
The sequence matters. Level first with blocks, then drop the stabilizers, then chock. If you try to level with the stabilizers, you will fight the ground and usually end up further off than when you started.
Tongue jack pads are the easiest to overlook. The tongue carries the heaviest concentrated load on a trailer, and running the jack foot onto soft soil without a pad is how pads sink and jacks bend. Two tall blocks like the Andersen 3608 pair are built specifically for this job.
What We Would Skip and Why
We left several popular options out of this list on purpose. Knowing what to avoid is as useful as knowing what to buy, and a few categories are not worth your money in 2026.
Unrated no-name plastic is the first. If a listing shows no load rating, no material, and no maximum stack height, the manufacturer either did not test it or does not want you to know. That is a different risk profile from a block that cracks.
Inflatable and air-filled levelers are the second. They are appealing because they compress flat for storage, but they depend on tire pressure, they perform poorly on gravel, and they cannot carry a heavy rig on soft ground.
Thin hollow plastic without a solid base is the third. Hollow blocks are lighter to carry and they are the first to deform on gravel, which is exactly the complaint that shows up repeatedly in forum threads about cheap sets.
We also skipped single-piece kits. One ramp or one block sounds economical, but a side-to-side correction needs at least two positions, and one of each means a second trip to the truck.
Finally, we skipped anything marketed primarily as a tire booster for a fifth wheel. Those products solve pinch flats on a heavy kingpin, not leveling, and conflating the two leads to wasted money.
Frequently Asked Questions
How many RV leveling blocks do I need?
Most owners need between 8 and 12 pieces, and the number depends on the depth of your worst drop rather than on your RV class. Each block adds roughly 1 inch of height, so a 2-inch drop needs two and a 4-inch drop needs a deeper build. A 10-piece set is the most common configuration and gives about 5 inches of tire lift while leaving pieces for the tongue jack and stabilizers.
How much weight can Camco leveling blocks hold?
The Camco 44510 10-pack we analyzed does not print a load figure on its listing, so treat any number in a description or graphic as unverified until you read the rating molded into the block itself. For comparison within the same roundup, the Lynx Levelers 11-Pack states 40,000 lbs and the Andersen Camper Levelers are rated for trailers up to 30,000 lbs. Always check the printed rating on the physical product before loading it under a heavy rig.
What is the difference between stabilizing jacks and leveling jacks for RVs?
Leveling blocks and leveling jacks raise the rig until it sits flat. Stabilizer jacks are not designed to lift; they hold an already-level rig steady on soft ground. Using a stabilizer to correct a tilt is what causes bent jack legs and damaged gear housings. Level first with blocks, then drop the stabilizers onto their pads, then chock the wheels.
Is it okay to level an RV with wheels off the ground?
Yes, that is the normal method. Raising one side with a load-rated block until the interior reads level on a bubble level is the standard way RV leveling works, and the block carries the load through the tire rather than through the suspension. Chock every wheel that is off the ground, plus any wheel on a slope, before you walk inside, and never exceed the published maximum stack height for the block set.
Do you put slides out before leveling?
No. Level the rig first, then put the slides out, because extending a slide changes where the weight sits and can push a previously level trailer slightly out. If you must move a slide to get into position, retract it before you finish leveling and re-check with a bubble level afterward. The same sequence applies to an absorption refrigerator, which needs to sit level to cool properly.
Can leveling blocks be used on soft ground?
Yes, but they will sink if you build the stack directly on sand or wet grass. Lay a plywood or particle board sheet under the stack first so point loads spread across a wider area. Solid-bottomed interlocking blocks hold position better than curved ramps, which have a smaller footprint and a slicker surface. On deep sand, drive onto the stack slowly and stop often to check the height.
Do I still need wheel chocks if I use leveling blocks?
Yes. Leveling blocks raise the rig, but they do not stop it rolling on a grade, and a trailer that settles overnight can shift off its blocks. Chock the uphill side of every wheel that is off the ground along with any wheel carrying load on a slope. Some complete kits, such as the CARMTEK premium kit, include chocks that lock into the leveler once the rig is level.
What are the best RV auto leveling systems?
For fifth wheels and larger trailers, built-in powered leveling jacks are the smoothest option because they raise and lower the rig from a remote or app without moving the trailer. Lippert Connect adds phone control to supported units, and six-point systems cover the corners directly. Blocks remain the better choice for travel trailers and for anyone who wants a kit that works without power.
Is Levelmate Pro worth it?
Levelmate Pro is aimed at fifth wheels and larger rigs with powered leveling, where it is a genuine convenience for owners who camp on sloped ground regularly. For a travel trailer with manual jacks it is overkill, since the same result comes from a ten-dollar set of interlocking blocks. Decide by your rig class and how often you move sites, not by the feature list.
What are common problems with RV leveling systems?
The recurring complaints are blocks cracking or deforming on gravel, stacks settling into soft or sandy ground after the rig is parked, and cheap plastic losing its shape and grip after a season or two. Owners also report curved ramps needing trimming for tight tandem tire spacing, wood blocks being left behind at the campsite, and lift ratings being inflated or missing from listings entirely.
Conclusion: The Best RV Leveling Blocks for Most Campers
After comparing all eight systems against printed load ratings, block dimensions, and real setup behavior, the Lynx Levelers 11-Pack remains the best RV leveling block set for the widest range of owners. Its 40,000 lb rating, roughly 1 inch per locked block, and USA manufacturing give you the reach and the peace of mind that most campsites require.
If you want speed more than versatility, the Andersen Camper Levelers fix a side in a single pass with continuous half-inch to 4 inch adjustment and a lifetime warranty, provided your tire spacing allows the ramp to fit. For a complete package with chocks, mats, and a bag already in the box, the CARMTEK kit covers the most ground out of the trunk.
Whatever you choose, read the printed load rating on the block itself, plan the stack before you arrive, and put a board down on soft ground. Our other camping gear picks, including our Bluetooth speaker guide for RV trips, cover the rest of a comfortable setup.
