Ours TT has flooded a few times granted it is not a new camper 1989 tip the front all the way up get a couple of fans going and towels at the very back to soak up the water get under all the cabinets and drawers towel dry leave all the cabinets open. Take some pictures in case you need to turn it in to insurance. I have not had any issues. There is nothing in our underbelly that would retain water.Most all of us have had this happen if you have been rv camping long. Another reason I dump my grey water in the bushes 24/7
