I have a Weekend Warrior Super Lite 5th Wheel. The floor was rotted away at the entrance (side) door in area about 30 by 20 in. It's a strange place since there is no plumbing there, although it...
After the camping season, I'll check my contacts and figure out where to go and what to do. The area is about 32 in wide by 18 in deep, right at the entrance door. I didn't see any wires or plumbing when I cleaned it all out and covered it.
