What the RV Industry needs and how it works.

Why are leaks still so common ? Is it poor workmanship (which I understand given the current high demand and lack of workers) or could the roof and wall designs be better ? I do not believe that cargo trailer have the number of water intrusion issues that TT have.

Sure water intrusion is the root cause of delamination and wood wall stud/floor rot, but there has to be a way to mitigate that. Better adhesives for bonding the skin to the aluminum/foam wall ? Better glue for plywood floors ?

I though composite floors would be a solution. It has been tried by several manufacturers with very limited success. (My suspicions are they used a wall design they got from the fiberglass "skin" manufacturer and just laid it down. This skins are NOT designed to take a perpendicular load, flexed too much and broke the bond.)


I am 100% with the OP. No evolution !

I think leaks are common because of poor workmanship. A careful owner will put "recaulking as needed" right at the top of his or her maint list. I literally check ALL of my seams three or four times a year, and touch up as needed with dicor. No leaks, six years now.

Yes a few of the mfr's are trying "composite" floors. Lance uses what appears to be filon or FRP on the bottom, styrofoam in the middle, and I believe luan for the top surface, covered with vinyl sheet. They do use azdel in the walls, but I "think" they are using luan for the floor. You should see what a tire blow out does to that sandwich composite. Ain't pretty.
