I was pondering that very question when I sold the trailer. Sounds like the hole is growing, though. It started about the size of a grape.
I was seriously thinking of putting a decal over it. I hated to think of having the panel replaced with the attendant possibility of leaks.
I will say, though, that Camper Clinic does a great job of replacing segments. A member of our unit backed his CCD into a tree. CC replaced the segments and I could not tell anything had been done.
Maybe you should go to the Homecoming in June and let the factory do it.
