RV Clinic: Tips for Travel Trailer Storage

Q. We have a Montana triple-slide fifth-wheel trailer. I store it on a concrete slab. Do I need to put anything under the tires while it is stored? Also, I am looking into a cover. What are the pros and cons and best recommendations? Thanks for your consideration.

A. It’s recommended that you park with the tires on pieces of plywood or other material that will keep them off the wet ground. It’s even better if you support the trailer on jack stands under the frame and take the weight off the tires and springs. The tires should be protected from the sunlight, too. If you use a cover, make sure it’s a quality cover that is designed to hold securely, so it doesn’t get shredded by the wind and doesn’t trap moisture underneath.

  1. We recently encountered a problem with the closet rod pulling out of the wall. We repared that with better brackets however the real remedy was: we constructed a support for the center of the rod made from Schedule 40 PVC pipe and a Tee. We slid the tee over the closet rod (to the center) and cut a length of pipe to the proper height to support the closet rod in the center. This works great due the fact we can easily move it if we need to support more weight on one side (coats and such). We also did not glue the pipe to the tee so it is easily removed to pack the closet. It works well because the support comes from the floor not hanging from above. The PVC works great because clothes won’t snag on it like on wood. It really doesn’t sweat like metal would either. In our case we used 1″ PVC schedule 40 pipe and fitting.
    Thanks for letting us share.
