I keep seeing so many stories about fiberglass walls delaminating and the such with luan as part of the construction. I see people who don't even have water damage and the walls are coming apart. So...
I read about people being told the roof needs to be "recaulked" or resealed twice a year! Lord help you if you look up each manufacturers reviews on Google. Very, very few have more than 3-3.5 stars. Nothing but water leak warranty horror stories on very new (less that one year old) travel trailers. Goes back to me saying I will negotiate to have the roof resealed at purchase. Apparently the guys at the factory do super sloppy roof jobs. I just don't get it.
