Sealing holes in underbelly

Hey all, recently purchased a Wildwood 30QBSS and upon inspection of the underbelly it looks like there are a few areas that need to be sealed up to prevent rodents from getting in. The underbelly is that tarp-like material and there is also a decent size hole in the plastic surrounding the fresh water tank for the low point drain.

Any suggestions on what to patch these holes with? The holes in the underbelly material are roughly 1-2" but the holy in the tank surround is closer to 5-6".

There are YouTube video of people using 3M type spray adhesive to stick fiber back in place. Google for repairing leak in black/gray water holding tank.


    Gorilla tape will work on the fabric, black foam is best used to seal around objects going through the Corrplast underbelly enclosure.

    Yup. Looking under the RV BEFORE taking delivery, not after.


    Great suggestion.. Didn't really feel like completely crawling under the RV that day since it was down pouring, a quick check around the perimeter looked fine. Additionally I think we all know there is ALWAYS something that needs to be taken care of with RVs.. something minor like this and other fixes isn't worth dragging it into the shop for.
  • No personal experience, but I've been told that Gorilla Tape works well for that type of patch.
