Water leak in travel lite truck camper has caused over cab bed area plywood to decay. Need diagram or schematic to determine best method of repair.

Hi brad, I had the same problem with a camper. I do not know of any available schematic, but would recommend dis-assembly of ceiling area to fix. It's not any easy job, but the only way to fix it properly. Remove all water damage section, make sure water is not pooling on the exterior roof. If it is collecting on the roof, you must brace it from underneath to raise any 'dips' so it sheds water, and make sure you apply a sealing coat (available at trailer stores, or on line) on the exterior. Also, if you park the camper when not in use, make sure you tilt it to help shed water more quickly. You have to use your carpenter and auto body skills to fix this. Don't put it off, I did and the roof deteriorates very quickly once you notice you have a problem. To remove plywood that is damaged, use a skill saw set at the minimum depth (thickness of the plywood) so you don't cut thru anything else. Use a drill to determine the thickness. To install new plywood, cut to fit the opening(s). Next get 3" wide by 3/4" thickness boards, place above cut out area, half on existing ceiling, half hanging over cut out, screw in thru existing ceiling into boards, attach replacement piece, screw into overhanging boards. You can putty over the joints, sand sand and paint, or just glue some sort of fabric to cover the area and make it look finished. Good luck!
