Among other things, there is water staining on the headliner around the entire interior perimeter.
Oddly, there is no delamination or soft spots anywhere except the front edges of the cabover portion.
The roof is solid. It obviously has leaked.
My main question, if I peeled the fiberglass off, what does the construction look like underneath? Wood? Metal? Foam? Fiberglass? Thanks.
I have a 2008 Tiogaearl 31w. I also have the factory drawings used in construction. If you get a message to me with your email I’ll be glad to send them.
It appears that the roof has 8 aluminum ribs spanning from side to side. Includes one at the rear and one at the cab over. These are 3/4 x 1 1/2 x .090 x 89 1/2.
There is also some plywood In Certain areas, Luan overall and some thin aluminum near the edges. They brace around openings, such as vents, AC etc with wood or aluminum.
I placed eternabond tape across the rear and where the cab over seal is when mine was new. Also sealed all fans, vents, skylight with the same. Eternabond is your friend.
I got the drawings from Bryan Gaughan at 1 800 322-8216. He is a factory customer service rep and was very knowledgeable and helpful.
Good luck. Tiogaearl
