yep, had all my floors in the main pass-thru bay and the water tank/wet bay totally replaced by Thor at the service center several years ago. Not only was water infiltration the problem, especially any bay directly behind, or in front of, the wheels, but I had strange/weird fungus plants growing mysteriously within the bays where the door wall meets the floor, it 'looked' like it was sealed from the factory, but apparently it just added to the 'migration' of species!

because Thor and other factories 'build' their boxes from plywood, this will continue to be an ongoing issue, especially if you travel much on wet/snow/muddy roads. The water is going to work it's way into the bay and sit there, and sit there... you get the idea.
Unfortunately, the 'wrap' the plywood used for these bay boxes with fiberglass 'wet proof' covering(the white stuff)... and while the covering is nice, there's a problem. Any and all edges that are 'cut' in order to build these boxes is now subject to water intrusion, and of course, long-term rot/mold/mildew growth. If all sides and edges are not wrapped by the white stuff BEFORE the boxes are screwed together, or the floor installed, then it's just going to keep happening.
