It's called Coroplast and has an endless variety of uses, including RV underbellies.

Yup. I make large RC planes out of it also.
Gorilla Tape, aluminum rivits, or with some difficulty super glue (but absolutely permanent). With super glue the coroplast needs a very brief flame applied to both sides, then glued.

+1 for Gorilla tape.

Gorilla tape - I used it 2 years ago, still stuck like the day I put it on.

I got my previous fw back from the dealership with warranty issues. After the first trip out, the tape they used came loose and was dragging behind the trailer. I thought it was crazy, taping a new camper the way they did. I forgot now, how many feet I got, but I just told them to get me the material and I would do it myself. I replaced the material from the cut to a support brace to the rear. I made the seam under the support brace, so it couldn't be seen. It was some work taking trim pieces off and everything, but it sure looked better than taping it and way more secure.

The tape used in RVs is called Scrim Shield tape and is available online such as here or can be purchased at an RV dealer by the foot. Mechanically fastening is better if you can do it, followed by tape. The tape can come off eventually as the coroplast is made from LDPE. For holes, landscaping expanding foam which is black/grey.

I replaced the washers on the seams with fender washers and then used the new very wide Gorilla tape.

I'd try a better tape first.

If that doesn't hold maybe try some scrap wood above the seams and screw both sides of the seam and tape over that.

I use the foil looking air conditioning duct tape. I have never had a problem with not sticking . Works very good. Home Depot, Lowes or hardware stores sell it .

If you Google "underbelly repair tape" you can buy a seam tape, but in my experience Gorilla Tape from Home Depot lasts the longest.
