Yes, some older RV were indeed made that way. However, more modern RV, have an aluminum or steel frame for the coach body. An aluminum frame is probably lighter and stronger than a wooden frame. I believe I saw something somewhere that Thor uses an aluminum coach frame. Also, my 2018 ACE defiantly has a flat fiberglass roof.
