Re: Repair of Class C
Hello Schizm:
I'd be happy to share my experience with you. Unfortunately, I didn't even think of taking pictures.
My first and most important pointer is, before you begin, make sure you've properly identified the leak(s)! We all know these are notorious for leaks, but I can only speak for my own experience. I thought I had properly assessed the situation and repaired a leak at the roof seam above my bunk. After I was done remodeling, I discovered a second leak from the side window which caused slight water damage to my rebuild work. Never underestimate the ability for water to move about and infiltrate nearly anything. It's all fixed now, though, and water tight!
My second pointer is sort of common sense also, but make sure you pull out ALL rotted wood. In my '79, the plywood was so badly rotted away, it was like composted manure (smelled a bit like it too! Whoooo-ee!). I cut back about 4-5 inches beyond the rot to make sure I got it all. Then, I doused it good with Fantastic spray to kill the mold and then ran a radiant space heater in the bunk are for 3 days to dry it all out. I didn't want any water trapped in there! It was dry as a bone when I put new materials in.
After ripping everything out of the bunk (paneling, decking, etc), I realized I have a metal frame all around the rv. This allowed me to weld 1 1/4" square tube steel from one side to the other across the bunk area to form a new substrate to which to attach a new 3/4" plywood deck. In the gap that was formed below the new bunk deck, I packed in fiberglass insulation to help insulate the sleeping area.
While I was at it, I built in 3/4" plywood walls flanking the entrance to the bunk area. Don't know if you know where I mean, but if you look at your bunk from inside the RV, far to the right and left, there is usually a gap above the bunk mattress and below the overhead storage bins that is filled with a curtain. In those places, I installed plywood for stability, some privacy, and as a place to attach pictures or other wall hangings. I glued decorative paneling to both sides and an edge molding to dress it up a bit. Turned out pretty derned nice, if I do say so myself.
Anyhow, I'll attach current pictures if I can figure out how to do it. I wish you luck. If you have a pressing question, don't be afraid to send it my way!
