Hope you get it fixed and back on the road again! We had a leak that I chased for almost a year until I finally found it....turns out it was where the aluminum roof meets the fiberglass end cap....the seal had broken, but not visibly. After applying Dicor self-leveling to the suspect area as well as resealing EVERY joint regardless of how it looked, I seem to have cured the leaks. We found the leak after it had gotten bad enough to cause the carpet to get wet underneath the bed and around the edges of the storage box underneath the bed. Spent the entire winter after that pulling EVERYTHING out, (bed, furniture, cabinets,...EVERYTHING that was slightly less than permanent) pulled all the carpet/padding....THAT was a job....and spent several weeks applying clorox to the wood flooring beneath to kill any potential mold/mildew. Kept several fans blowing inside to dry everything out and then installed FLOR brand floating carpet squares. That way we can remove a single carpet square and replace it if necessary instead of having to pull an entire section of laminate boards or tile. We're happy with the end result, but really hated all the work that went into getting it done.
To your question on running the A/C year round? No, we don't, but we DO keep a floor fan running and the roof vents open to ensure circulation throughout. A dehumidifier is a good idea too.
