I started by stripping all the wiring and wood from the frame. I then wire brushed the entire frame, painted it with two coats of primer and then three coats of Rustoleum. Next I replaced all the wiring and added new LED lights. For the wood I used exterior plywood for the deck and pine for the sides. I made the front and back removable for flexibility. All of the wood was stained with exterior "natural" stain for longevity. I repacked the wheel bearings for safety. Once the wood was cured and dried I then, today, put it all together. The pitures below shows the results. Can't wait to do our first camping trip now. Guinness loves it.
