I had to repair and replace landing gear equipment on my 5th wheel trailer several times. One of the problems with the landing gear is that the legs “move” when you're raising them causing a rocking motion. I always used boards to allow the landing gear feet to be able to “slide” when I was raising them.

This would help, but not prevent, chassis twisting. Chassis twisting is what causes caulking to crack under the overhang and will also cause the holes where the landing gear protrude to expand leaving visible “gaps” in the structure. By using “Snaps” Manufacturing, Leveling Wedge Blocks, you’ll eliminate these problems. Use a pair of wedges to chock the rear wheels and then back-up the rig onto the wedges. This (combined with use of the wedges on the landing gear) takes the pressure off the king-pin allowing for easy un-hitching without having to put the truck into gear and rocking back and forth until it releases.

Next, lower the landing gear to about an inch or so from the ground and slide a wedge under each landing gear foot until they make contact and are relatively centered. Continue to lower the landing gear like normal. This procedure ensures that the landing gear legs are equalized and raise and lower the 5er without twisting the frame. This is especially important on rigs that only have one motor operating the landing gear.

Snaps Leveling Wedge Blocks are made from recycled dense plastic and are guaranteed for life. You can purchase these from Camping World or your local RV store. Learn more about this product here:
