Fiberglass roofs
Our Motor Home has a fiberglass roof, which I really like, as it is all one piece. Do any of the current builders or coaches still have these?? I have seen a lot of damage and failures on the rubber...

Quite a few times I've seen motorhome and trailers (mostly trailers) with rubber roofs and you could see the glue holding it down had given way and the roof material was bubbling up. The driver probably had no idea it was doing that since it was only visible at freeway speeds. My guess it most of those roofs were probably close to failure.
I have a fiberglass roof on my motorhome and never had any issues. I even hit a tree branch once that destroyed my bathroom roof vent and did nothing to the roof. I've heard stories of people tearing holes in the rubber roof with tree branches.
As to roof bubbling going down the road. It is NOT because the glue failed. The Rubber is installed UNDER the front Cap or front metal overlay and screwed down with a metal strip. IF there is anything that allows AIR to get under the cap or that sealed front edge, that will allow air to be forced under the membrane and slowly brake the adhesive loose and cause that bubbling. Even if you had a non glued Rubber in front, if sealed correctly, without air being forced under it, it will not bubble going down the road. Doug
