So I addressed this today. Had a heck of a time finding rubber to use, so I trimmed a piece from under the second row seat. Shouldn't be an issue, as it's elevated and out of the way. I then trimmed the peeling piece in the front and gorilla epoxied the new piece from the second row. Once that dried, I went over it all with a heavy coat of spray bedliner. Not my prettiest repair, but I think it'll be water tight, and that was the goal.
Thanks for the input!
