construction materials
I was looking at this RV today as I am retiring in June and husband is already retired. We have a 21ft travel trailer but we are thinking about getting something a little bigger and easier to handle....

You may want to check out Newmar. Their walls aren't laminated so delamination is never a problem. So far I have not found any OSB in mine. OSB is very heavy and I don't know why anyone would want it in an RV.
Newmar does have delam, but it is extremely rare. ALL RV's can have delam, but it is very rare. Newmar has what is called a HUNG wall. That means they install Sikaflex adhesive up and down and sideways to all the aluminum studs and then the wall which is hung from clamps is then pressed onto the sidewall of the RV. The sidewall has already been secured to the RV floor. It is then blocked with wood rams that press against the wall and is left overnight. They clamp 2 to 4 or 5 units this way overnight. The only time I have seen delam on a Newmar was when they missed a stud with Sikaflex and that was years ago. Due to the aluminum studs and the Sikaflex adhesive, water penetration will not cause the Newmar to delam. Water penetration is the usual cause of Delam when they use wood studs and styrofoam and the studs get water and the adhesive lets go. Water damage on OSB or any type wood will NOT cause a problem UNLESS the water is left to sit for weeks or months. Having a water leak and then drying it out will not cause any floor material to swell up immediately. Doug
