Sunseeker Construction

[vjstangelo]

I note that Forest River Sunseeker Class C advertises no wood construction in the walls. What does this realistically mean?
If water gets into the wall will there be no structural damage?
What about the floors/roof?

My current TT uses composite wood construction and water will cause delamination/destruction of the luan. I swore that the next camper I buy will not be of wood construction.

I doubt the walls have steel studs. Most use aluminum for the house frame. FR also does not have luan substrate (wood) under the fiberglass for the wall material. They use walls with something called Azdel which is relatively new to the industry. You can look it up.

That means the walls & roof use aluminum framing. It makes for a better structure assuming other good practices are in place. Wood expands and contracts with the change in seasons which is harder on caulk-work. And as you pointed out, wood can hold water and rot when gotten wet.

Regarding floors, most if not all RV manufactures use steel beams with wood over it. Low end models get chip board. The better ones use marine plywood. Some brands like Phoenix Cruiser get a thick plastic corregated under-belly protective barrier with foam block insulation in between. Admittedly I am not familiar with every flavor construction method in the making of floors, walls, and roof.
