I have the same exact issue. Have a 2003 camper that had a leak when I bought it. Guy fixed leak but small corner of roof is gone. Otherwise camper is mint condition..
I lose sleep over it trust me. For me I have aluminum siding and was thinking to pull the corner strips off, and remove rear siding. Thats would include all the marker lights and tail lights.
Then remove side trim back some 5 ft and roll the roof back..
Then I can fix that corner and have piece of mind. Then when done put that liquid roof on it...
Done.. new camper..
But its so much work and I am not a carpenter..
So it goes on year 3 and I am still camping and have done nothing. I do keep an eye on that area though..
Yes that corner is just rubber roof with a 8x4 triangle missing from the wood underneath.. And I removed the shower surround to have a look and the luan near the bottom of the tub is just paper now. The wood is gone? Guess its wall paper..
They want 4 K to fix it all.. I said no way I only paid 5k for the camper..
So I hope you get some responses..
Oh below is the best video I was going to follow if I ever attempt to work on mine...
