Prime 1 PR1ME Camper Leveler, 2 Pack RV Leveling Blocks, HDPE Curved Levelers, Include 2 Curved Levelers, 2 Chocks, 2 Anti-Slip Mats and Carrying Bag Review (2026)

What comes in the kit

This 2-pack includes two curved HDPE levelers, two matching wheel chocks, two black anti-slip mats to place under the levelers, and a carrying bag to keep the full set together in a storage bay between camping trips. Rather than stacking flat interlocking blocks to reach a given height, the curved leveler shape lets a tire roll up a single ramp until the RV reaches the desired level point, then the chock locks in behind the tire to hold that position steady. Manufacturer listings for this design state it can accommodate vehicles up to 35,000 pounds with tires up to 32 inches in diameter, covering most RVs and trailers on the road.

How the curved design levels a rig

The curved levelers are built with a stepped or gearwheel-style surface so a tire can be positioned at a specific height rather than only at the fixed increments a flat stacked block would allow, and product listings describe leveling in increments from about half an inch up to 4 inches of total lift. This is faster in practice than repeatedly stacking and restacking loose blocks to sneak up on the correct height, since the driver can often find the right spot in one or two forward and backward movements instead of several attempts with individual blocks underneath the tire, saving setup time at each new campsite.

Axle compatibility

Manufacturer and retailer listings for this exact PR1ME design describe it as sized to fit most dual axle trailers without needing any modification, alongside standard single axle use, which runs against this site's own note that it suits single axle wheels best and needs spacing checked on tandem setups. Buyers with a tandem axle trailer should not assume this kit is a poor fit based on that concern alone, though it is still worth test-fitting the levelers against a specific trailer's exact axle spacing at home before relying on them at a remote site with no backup plan available.

Chocks, mats, and grip

The included wheel chocks are designed to sit behind the tire once it reaches the target height on the curved leveler, preventing it from rolling back down while the rest of the leveling process continues on the other side of the rig. The anti-slip mats go underneath the HDPE levelers themselves, adding grip against pavement or packed gravel so the leveler does not slide forward under the weight of the tire climbing onto it. HDPE is a tough, moisture-resistant plastic, which suits a product that will sit outside in mud, rain, and direct UV exposure over repeated camping seasons of use.

Who this kit suits

This kit fits RVers who want to level a trailer or motorhome by rolling a tire up a curved ramp rather than repeatedly stacking flat blocks, since the one-motion approach can be quicker at a site with an awkward, uneven grade. The included chocks and anti-slip mats round out the kit so nothing extra needs to be bought separately for a complete leveling setup. Very steep sites will still exceed what a curved leveler can lift on its own, so pairing it with a few flat blocks underneath for extra height is still worth keeping in the storage bay as a backup.
