Hey guys, while investigating my lighting issue I came across a grim discovery that I can't really decide what to do about. My interior roof panels seem to be rotted. This isn't the normal drip rail problem (it has rail rust but no holes I can find). Rust spots formed on the interior panel that developed into holes. Just looking into the holes I can see rot on all panels and there is loose pieces of the interior sheet metal panels near the worst hole. I know I'm just gonna have to cut it open and find the worst of it, but right now I'm expecting the worst since I can push up on the passenger side panel and hear the sound of rust crackling. Should I try and find a donor cab for roof panels? A cab swap is out of the question because of cost. Anyone here have experience with fixing interior rot? The truck only has 61k on the body and I'd hate to have to do anything like swapping cabs. It's really sad too because besides the roof and the bed arch it is almost 100% rust free. Sorry if I'm getting into emotions too much, I'm just really saddened by the discovery. Any tips or help is appreciated.
