    I see you are new here, so welcome to the forum! We have the same floor plan!

    My suggestion for a repair of that type is to use this stuff…

    Good Luck and let us know how it goes.

    A good quality scrim tape would also work well.

    There is a zipper in the aluminum belly liner just behind the pull handles for the holding tanks, I assumed it was for access to the tank valves if needed, but I'll have another look when I'm at the trailer this weekend

    Our trailer is a 2021 bought in Dec 2020

    Thanks Bill - for the belly patch or scrim tape suggestions, I'll give that a try

    Please let us know what you see. It may be remains of a presale repair.

    I have a 2020 purchased in November of 2019, no zipper.

    Checked and no zipper.

    I'll bet it was opened by the dealer pre sale to you.

    I had a closer look and there is a cover patch with a zipper ( approx. 12" x 18") over a cut in the black liner under the black holding tank. The cut looks professionally done and the zippered patch matches it perfectly. Didn't look like any repairs had been done. The patch is starting to peel off so I just taped it up for now until I get some proper scrim tape.

    Thanks for the follow up. It would be awesome if you could take some pictures that would really help visualize it.
