So my wife and I got a camper (2006 Starcraft Centennial 3608) that needs a little work. She has been browsing some sites and getting ideas for redoing floors, counter tops, curtains, and upholstery and we are excited to make this our own. I did however miss some wood rot on it before I purchased it which sucks, but it was a learning experience. We have a workshop to work on it in and most weekends free so I am ready to get started. I am not sure of the proper terminology so my google searching and looking on here was not able to provide many results. I have seen videos of people doing complete restorations down to and including painting the frame, so I am hopeful this is not impossible, just time consuming. The issues: 1) There are some soft spots on the side walls of the roof in the corners. It does not go far back, or look bad, just a bit of caulk from the previous owner. When knocking on it, I do hear the sound change to a more solid knock the further i get from the corners. 2) The front of the roof where if bends down feels soft, but I cannot tell if this is normal. There are no cracks, discoloration or anything of that sort. It almost feels like this area is a bit hollow, but not the same as the bad wood. 3) This is the worst of it, and I am not sure how I missed this before getting it. The front driver side corner has a good bit of caulking and the roof retaining clip's screws seem to be not only not-original, but completely rusted. When towing it home, it actually popped out and the roof started shaking. I bungeed it up and got it in the workshop, but i was able to just wiggle the rusted remains of the clip out of the wall. Inside is wet, soft, flaky wood. This must be replaced. I have seen some videos of people taking the side of the PUP off and replacing wood, but since this is where the hot water heater is, I wonder if I could go inside and replace it from the inside out. I am planning on getting it put up this Saturday afternoon, spending Sunday surveying the damage, and then on Monday hitting the store and starting some repairs. Does anyone have tips or resources that may help me in my endeavor?
