Two trips to the dealer, the last time for 2 weeks, and the flooring problem still hasn't been fixed and the dealer says they don't know what is causing the problem or how to fix it. A water leak from the shower has been eliminated as the problem. My current thought is there is too much flex in the frame or floor in that area of the coach. Still looking for an answer but visually the floor around the shower looks like crap. Any ideas?
