Jayco- Condensation and walls bubbling

[SCC]

My Jayco 26lL puchased new 2 1/2 years ago is suddenly getting lots of condensation along the ceiling/walls and one of the walls on the inside of the trailer is now bubbled (like hard little rocks under the the wallpaper). Anyone else experience this? I'm hoping Jayco doesn't pull the "you are 5 months out of your warranty" game. It's headed to my dealer in a few weeks for a looksee. I looked at the roof adn it seems fine; it's like one big rubber blanket and the cauk around the vents/etc see fine.
Thoughts? Comments? Suggestions?
Thanks!!!

That sounds ominous. Ask your dealer if they have a Sealtech Manufacturing Inc. - RV leaks bubbles recreational vehicles
Sealtech machine. I suggest you have a water leak somewhere; the Sealtech machine pressurizes your RV to about 2-3 psi. This is just enough to detect leaks. They spray the outside with a soap/water solution after starting the machine. Ours had a water leak upon delivery. Using the machine my dealer's service dept. located 4 leaks, the one I complained about, and 3 others I didn't find. The one I found inside_ the entry point was about 14' from there.
