Your two months out of warranty. Did the dealer say Jayco would not cover it, or have you spoken directly to Jayco?? Personally I would make sure I contacted Jayco, to verify they will not cover it, as the dealer can charge you more than what Jayco will pay them.
The issue is the staples are not holding it to the wood framing. I have not resided a TT, but it does not look to hard. They are sided from the top down, so you have to remove each panel working your way up. As you put it back together you will need to replace all the sealants.
I like this video of a TT being resided.
