We just bought a 2008 GS SuperNova and it appears there was a leak by the fantastic fan and the ceiling has kind of like bubbled and made ripples. Do you have any idea how to repair that?
Yes, Sudsy, if you have a fiberglass roof, you can rap on it with your knuckles and it should sound the same as the end caps and outer wall skin, a hard surface, no rubber skin over it. They may have done a sloppy job with the sealant (maybe wrong stuff, as well) but at least at this stage you don't have any worries about the rig rotting down around your ears.
