The CAMCO MFG 44428 is a curved leveler and wheel chock designed to keep RVs and trailers stable and level on uneven surfaces. The curved ramp profile lets the tire roll up gradually to the correct height, and the integrated chock function holds the wheel in place once positioned. Sold as a 2-pack, the 44428 is a straightforward mechanical leveling solution that does not require power or special tools to deploy. The set weighs 6.57 pounds total, making it easy to store in a tow vehicle or trailer bay. Technicians, fleet service crews, and owner-operators who regularly set up temporary sites rely on this type of chock-leveler combination for fast, repeatable results.
The 44428 is suited for use under single axle and tandem axle trailers, Class A, B, and C motorhomes, fifth-wheel rigs, and utility trailers parked on asphalt, gravel, concrete, or packed dirt. The two-piece pack allows simultaneous chocking of both sides of a single axle or independent placement on dual axles. It is a practical inclusion in any service vehicle or on-site kit where temporary stabilization is needed during maintenance work or overnight stops.
Designed as a general-purpose leveling chock for RVs, motorhomes, and trailers with standard rubber tires. No specific model or system exclusions are noted in available product data.
Place the chock in front of or behind the tire in the direction the vehicle would roll on the grade before releasing the tow vehicle or setting the parking brake. Confirm the tire has fully seated on the curved surface before considering the rig level. No tools are required for placement, but wheel blocks should always be used alongside the vehicle's built-in stabilizer jacks, not as a substitute for them. Inspect the chocks for cracks or deformation before each use.
