How do you fix this ?

Needed in my opinion. And not just the roof.

I went all around our 1 year old trailer this year with some marine grade silicone caulking and was amazed at all the cracks and holes I found in the old caulking. Makes me wish I did it when the trailer was brand new actually.

More preventative. It's drying out. I've done some of it already. I've worked boats all my life I know when to redo caulk. I'm going to get this season done first. Caulking was already a planned project. Coating the roof was in the research phase.

I would second this!! If the caulking is deteriorating I would not chance getting a leak and if you can't get it done yourself ASAP I would pay the dealer to do it. It really doesn't take them that long to do and should be relatively cheap.

It's not as bad as the service tech claims. Yes it needs attention soon but it can wait til Fall. Again I've worked on boats all my life, I know something about fiberglass and caulking, especially when a leak means you sink.

is this fiberglass laminated over plywood?
If it is, it's easy (by boating standards) to be fixed.
If you found and solved the leaking problem, just grind the fiberglass off, cut the rotten plywood off, put new plywood in and use epoxy resin to laminate over it again.
There are tons of "how to do it" videos around.
You save a lot of money doing this.
The resin and all that stuff you can buy at Noah's ...

Most of a "Fiberglas" RV is not actually fiberglas, it is a Fiberglas Reinforced Plastic, similar, but thinner, than what is used on commercial Restaurant/bathroom walls. More typical fiberglas is used on curved front and sometimes rear panels. So repairs may not be the same as regular fiberglass as used on boats etc.

This is what many Mfg use, thickness varies by type of RV. with class A being thicker material etc.
