Hi everybody. This is my first post, but I've been reading and learning a lot here. I really appreciate all the help I've already gotten. Unfortunately too much of my research was done after we bought a pop-up, not before. We bought a 2004 Starcraft Centennial 3600 about a month ago. The 4 roof sidewalls, and filon top are shot and need replaced. Some warning signs were there, but between the excitement from the kids, the wife, and myself, I missed them. Completely my fault. I've been really bummed out about the situation, but it's time to stop moping and get things fixed. I've searched and read about a lot of roof rebuilds, but I still have a few questions (please give me any advise you have). My plan is to make sidewalls out of 1/2" plywood. I've made the front and back boards, and I have my sideboards lap jointed, glued, and rough cut with the jig saw. I was going to laminate them on both sides with white vinyl flashing (bought at Lowe's). Planning on using contact cement for this. Is that a half-way decent plan? To replace the filon top, I bought a superflex alpha rubber roof kit. I plan on covering the top of the roof with luan, and glueing the rubber roof to that. Is that my best bet? None of the wood I have used/plan on using is pressure treated, so should I apply some kind of waterseal (like Thompson's)? I don't plan on it ever getting wet again My last question (for now), it seems the rubber roof should only cover the top, and front and back boards, not the sideboards( just like the original filon did). How do I possibly apply the superflex glue to the top, front and back boards without completely gunking up the vinyl-flashed sideboards? Does my plan make any kind of sense or should I make changes? Thank you all for the help, I'm tired of losing sleep over this thing, and ready to start making memories with the family!
