An unlevel RV is more than an inconvenience — it can throw off the absorption fridge, make cooking and sleeping uncomfortable, and put uneven strain on the frame and jacks over a long stay. Leveling blocks and wheel chocks are inexpensive, low-tech solutions to a problem every towable RV owner eventually runs into at an uneven campsite.
The two dominant approaches are interlocking stackable blocks, which build up to a custom height, and one-piece curved ramps, which level the rig by driving up a curved surface in a single pass. Wheel chocks are a separate, complementary item: they stop the rig from rolling once it's positioned, and are not a substitute for leveling gear.
Weight rating matters more than it might seem. A set of blocks rated for a lightweight pop-up trailer is not necessarily appropriate for a heavier fifth wheel, so check the manufacturer's stated capacity against your RV's actual loaded weight before relying on any leveling product.

The picks in detail
Best Overall
Andersen
Andersen Camper Leveler (Curved Ramp)
A curved, one-piece leveling ramp designed to level a trailer or motorhome in a single drive-up motion, paired with a locking chock to hold position.
Why it stands out
The curved one-piece design lets the driver level the RV by simply driving up the ramp, without stopping to add or remove blocks.
Best for
Owners who want to level in one motion without stacking blocks
Not ideal for
Owners needing to level extreme side-to-side tilt beyond the ramp's curve range
Key features
- ◆One-piece curved ramp design for single-motion leveling
- ◆Included locking chock to secure the tire after leveling
- ◆Carrying strap and storage bag included with most kits
- ◆Works for tandem-axle trailers when used one side at a time
- ◆No stacking or assembly required before use
Pros
- Very fast to use compared to stacking individual blocks
- Includes a locking chock in the kit
- Compact for storage relative to its capacity
Considerations
- Higher price than basic block sets
- Bulkier single shape than flat stacking blocks
Final verdict
Andersen Camper Leveler (Curved Ramp) suits buyers who prioritise owners who want to level in one motion without stacking blocks. Worth knowing: The amount of correction possible in one pass is limited by the ramp's curve, so very uneven sites may still need extra support.
Best Interlocking Blocks
Camco
Camco FasTen RV Leveling Blocks (10-Pack)
A set of interlocking plastic leveling blocks that stack together to correct side-to-side and front-to-back tilt for trailers and motorhomes.
Why it stands out
The interlocking tabs keep the stack from shifting under load better than simple flat blocks stacked loosely.
Best for
Travel trailers and smaller motorhomes needing quick leveling
Not ideal for
Heavier Class A motorhomes needing a single continuous ramp
Key features
- ◆Interlocking design so blocks stack securely without sliding apart
- ◆Textured surface intended to improve grip in wet conditions
- ◆Compact stacking for storage in a bay or bin
- ◆Sold in multi-piece sets for building up multiple heights
- ◆UV-resistant plastic construction
Pros
- Inexpensive and widely available
- Compact for storage
- Works for both leveling and wheel chocking in a pinch
Considerations
- Not rated for the heaviest Class A rigs in tall stacked configurations
- Manual stacking takes longer than a one-piece ramp
Final verdict
Camco FasTen RV Leveling Blocks (10-Pack) suits buyers who prioritise travel trailers and smaller motorhomes needing quick leveling. Worth knowing: Building a taller stack for significant unevenness takes more blocks and more time than a single curved leveler.
Best Budget Ramp
Camco
Camco Tri-Leveler Curved Ramp
A curved tri-level ramp offering three height settings in one compact unit, designed as an affordable single-piece leveling option for trailers.
Why it stands out
Three height settings in a single small unit give more flexibility than a fixed-height block without buying multiple pieces.
Best for
Smaller single-axle trailers
Not ideal for
Heavier multi-axle rigs needing higher weight capacity ramps
Key features
- ◆Three built-in height levels selectable by orientation
- ◆Curved surface for smooth drive-on leveling
- ◆Compact, stackable-for-storage shape
- ◆Works on single-axle trailers and smaller rigs
- ◆Textured tread for tire grip
Pros
- Affordable one-piece design
- Multiple height options in a single unit
- Compact and lightweight for storage
Considerations
- Lower weight capacity than premium curved levelers
- Less stable on very soft or uneven ground without a base pad
Final verdict
Camco Tri-Leveler Curved Ramp suits buyers who prioritise smaller single-axle trailers. Worth knowing: Weight capacity is generally lower than heavier-duty curved levelers built for larger rigs.
Interlocking blocks vs. curved ramps
Interlocking stackable blocks, like Camco's Lynx Levelers, use tabs that lock adjacent blocks together so a taller stack resists shifting under the tire's weight. They're versatile — you build exactly the height you need — but stacking several blocks for a significant tilt takes longer than a one-piece ramp.
Curved one-piece ramps, like the Andersen Camper Leveler, level the RV in a single drive-up motion along a curved surface, which is noticeably faster to use once you're used to judging the approach. The trade-off is a fixed range of correction; extremely uneven ground may still need a block or two underneath the ramp for extra height.
Wheel chocks are not optional
Wheel chocks prevent the trailer or motorhome from rolling once it's positioned and leveled, and they should be used every time regardless of which leveling system you choose. Some curved levelers include a locking chock as part of the kit; if yours doesn't, buy a dedicated pair separately.
Chock both sides of a wheel, or both sides of a tandem axle set, rather than relying on a single chock on one side only — a single chock can still allow rocking motion when entering or exiting the RV.
Checking weight limits
Every leveling product has a stated weight capacity, and it's specific to how the load is distributed — a rating for a single stack under one tire is not the same as your RV's total loaded weight. Check the manufacturer's packaging or product page for the exact per-tire or per-stack rating before use.
Lighter product lines, such as basic flat stacking blocks, are usually intended for smaller trailers and pop-ups; if you're leveling a heavier fifth wheel or a larger travel trailer, look specifically for products marketed toward that weight class.
Storage and portability
Leveling blocks and ramps take up meaningful space in an RV's exterior storage bay, so consider how a given product stacks or nests for transport. Interlocking blocks generally stack into a compact brick when not in use; curved ramps are a fixed single shape, though many ship with a carrying strap or bag to make handling easier.
If storage space is tight, a smaller multi-level ramp or a compact block set may be preferable to a bulkier curved leveler, even if it takes slightly longer to use at the campsite.
Frequently asked questions
Final verdict
A curved one-piece leveler like the Andersen Camper Leveler is the fastest and least fussy way to level most single- or tandem-axle trailers, and its included locking chock covers both jobs in one purchase. Owners who prefer a more customizable setup, or who tow a heavier rig needing a taller stack, should look at the Camco FasTen interlocking blocks instead, and budget-focused owners can consider the Camco Tri-Leveler curved ramp. Whatever leveling system you choose, always add a dedicated pair of wheel chocks as a separate accessory — they're inexpensive insurance against a rolling trailer.
