I just aquired a cab over for trade of my camper shell. The paneling in the front roof part has warped due to water damage. Has anybody had any experience replacing whole panels before on one? I just wanted to get an idea of how they are held together and how much of a pain in the a$$ it is. I don't plan on keeping it, my truck is a little unstable hauling it around because of the lift. I just want to fix it up a little and sell it for some $$$ and put it into my motor.
