The Wobble Stopper dramatically reduces camper jack/frame stress. It attaches to the front camper jack legs and camper body to prevent sway while the camper is sitting on its jacks. The Wobble Stopper nearly eliminates camper movement, is fully adjustable and has square or round jack applications. Composed of stainless steel and aircraft grade aluminum. Not only do the Wobble Stopper™ braces make it more comfortable in your camper by eliminating that irritating sway that can make you dizzy or even nauseous, but they also help to reduce wear on the camper frame where the jacks bolt to the camper. This reduces the need for costly repairs later on.
