Stop fighting an unlevel campsite. The Camco 44501 leveling block set gives you a simple, stackable system to get your RV level on uneven ground -- whether you're running single wheels, duals, tandem axles, or any type of jack. Four blocks and a storage bag, ready to go wherever you do.
The Camco 44501 uses a tongue-and-groove interlocking design that lets you stack blocks to whatever height your site demands. Each block adds roughly 1 inch of lift, so you can fine-tune your level without guessing. The solid bottom surface resists sinking into soft or loose ground -- an important feature for grass, gravel, or dirt pads where hollow designs can dig in.
At 8.5 x 8.5 inches per block, the footprint is wide enough to support large tire contact patches on both single and dual rear wheels. The same blocks double as jack pads under hydraulic leveling jacks, tongue jacks, stabilizer jacks, and 5th-wheel landing legs -- so one set covers your whole rig.
Tongue-and-groove edges lock blocks together securely. Stack as many as needed for the height your site requires without the stack shifting underway.
Fully solid base resists sinking into soft grass, gravel, or dirt -- unlike open-grid designs that can punch through loose surfaces.
Works under single wheels, dual wheels, tandem axles, hydraulic jacks, tongue jacks, stabilizer jacks, and 5th-wheel jacks. One set does it all.
All four blocks store in the included mesh/fabric bag -- keeps them together in your basement storage bay or truck bed between trips.
Each individual block is 1 inch tall. Four blocks stacked yields up to 4 inches of lift at the wheel or jack point. Because the interlocking design is self-aligning, you can build a stable column quickly even in low-light campsite conditions. For applications requiring more height, Camco's larger 10-pack (44505) uses the same block design and intermixes with these blocks.
Placed flat under hydraulic leveling jacks or stabilizer feet, these blocks spread the jack load over 72.25 square inches (8.5 x 8.5 in) of ground contact. This is especially useful on asphalt in hot weather or on soft campground soil where a small jack foot can sink or crack the surface. The 4,000 lb per-block rating gives ample margin for typical RV corner jack loads.
Camco manufactures the 44501 blocks domestically from high-density plastic rated for outdoor UV exposure. The yellow color is molded in, not painted, so it won't chip or flake with normal use.
