We have a 1997 Fleetwood Coleman Sun Ridge that we bought used. It’s our first pop up, but we’ve owned it for about three years and camped in it several times, including a cross country trip. The front box is in terrible shape and the worst part is that water has gotten in and damaged the front wall of the camper. (What’s the right term for that wall? I believe I’ve seen some call it a bulkhead and others call it a firewall) Well, that wall will need to be rebuilt. It has torn away from the sidewall. That led to extra stress on the bunk slide out, causing the rivets that hold the small wheel to the bunk to shear. I’ve also got some softness in that corner of the main camper floor, and I think I can handle replacing that when I’m working on the front wall. My plan at this point, after reading a lot of forum threads, is to rebuild the front wall out of wood and not try to fix this storage box, at least not now. I’m not sure about the best way to go about riveting the bunk rail back together. I’m also concerned about making the front wall connection sturdy enough so that the bunk is held up safely. Finally, I want to make sure the covering I make for the front wall is waterproof so I don’t run into water damage again. I was considering sheet aluminum or perhaps aluminum diamond plate. I’m also considering a sheet of FRP (fiberglass reinforced plastic). I’m looking for advice on any of those concerns and for any input on what I have failed to consider and should look out for. Thanks to everyone who has posted valuable info in the past. I’ve already learned a lot. But, I need some more help. If people are interested, I'll add some photos.
