I have seen FRP (fiberglass Reinforced Panel) used on several different Campers and on the ceiling of a 27' Hi Lo. Owner told me is was a breeze to shape and install. He used the suggested joint strips between them. Really looked clean and brightened the place up. This was also the owner who helped me install curbside lower walls on his unit, obtained from a PODS repair facility. That siding is a bit thicker and a lot tougher than original, but installed perfectly.
