Our Camco large stabilizer jack pads help to keep jacks from sinking into the ground. These RV jack stabilizer pads come with a built-in handle and are constructed of rugged UV stabilized resin. The rib design lends greatly increased strength to each pad. A storage strap is included and comes in a 2 pack. The stabilizer jack pads are much lighter in weight than carrying pieces of wood and can be stacked on top of each other to help level your RV as well as give the extended jacks a stable place to rest on.
