I have a pretty serious question and would like any suggestions or feedback I can get. We have a 2006 Adirondack Travel Trailer. The floor is very soft by the kitchen sinkand has spread to either side. I have reinforced the floor from underneath with angle steel bolted to the steel crossmembers and 5/4 deck boards bridging the span. The floor is solid now but I have discovered that a leak has caused the problem. The dealer zoomed me into thinking it was just a design thing and would be fine with a little reinforcement. They stuck a one by six above the crossmember and sent it back. Like an idiot I believed them. Anyway, the trailer has a foam core floor(I think it is called) about 1/8 luan with 1.5 - 2.0 of styrofoam with another 1/8 luan below. It is wet (not sure how wet) and spreading. My plan is to remove the flooring, dry it out and glue laminate flooring over the luan. After locating and fixing the leak, of course. Originally I thought I would cut the floor out and patch it but I began to think that styrofoam is inpervious to water so why now leave it. One concern is that a large slide out glides over this floor so I am worried about how thick the laminate flooring can be. The other thing is I get conflicting information on whether I can glue laminate down or not and why (either way). I don't think it will work well floating so if I can not glue it down, I need to do something else. My question is also, has anyone done anything similar? These leaks seem to be quite common.
