I have a 3 year old Rockwood Roo with a hard rear slide. Over the past few months I have been developing some soft small bumps under the wall paper on the rear wall adjacent to the slide out. It feels spongy like styrofoam. I can't see any leakage along the roof or see any signs of water leakage inside the TT. Anyone had similar problems that can share their experience?
I have no experience with bumpy wallpaper. But every poster over the last few years with bumps under the wallpaper has found them to be mold caused by a leak. Take a sharp knife or razor blade and slice open one of the bumps and see what's inside.
