After several long multi-state trips this past year there was never a hint of a leak. Till yesterday. We took a 4 day trip up the north California coast and saw lots of rain with several hours of high speed windshield wiper variety on the way home. The very rear floor was damp. We originally rebuilt some rear floor but never re did the belly pan material there and I can see the problem area. Also, where the 1/2” black fiber remains much of it is soaked and falling apart now. my idea is to cut and remove the rest of the black board and what glass insulation remains and let it all dry good. Then not sure. The style is 1/2” board between the steel frame and wood 2x2 joists which of course is smashed flat. I have replaced most bolts and used 1/2” hard rubber washers to try and fill the void. Whole new sheets as original is almost impossible. I can flash over the areas that leak behind the wheels and paint(or not) the wood, or try and piece in panels of something between the metal framing members. I’m not overly worried about insulation, but it would be nice. Any one ever use small mud flaps to lessen the hit behind the wheels? Any ideas on a pan? Thanks.

Wet bellies usually come from above. Sometimes road wash will get things wet but not saturated. If you don't care about insulation for now, remove the damaged belly, let dry. After you discover the culprit, you can paint the floor underside with rubberized goop. Keep a close eye on the underside for leaks coming from above during rainstorms. Most of the damage I've seen sneaks down a wall cavity and settles inside the belly. Metal is the worst as most fiber bellies breathe a little bit.
Sorry this has happened.
