Condensation Under Mattress

Yep, we did just what bikendan mentioned. The product we used was Hypervent, but looking at the above-mentioned product site, it seems very similar. Our ROO was an '07 and IIRC, we bought the Hypervent after going through the first fall with our HTT. The cost for one bunk at that time was $106.00 incl shipping. We also had the high wind PUGs but did not use reflectix in the windows. DH was pretty adamant about opening a window or ventflap when it was freezing outside and we were trying to get the inside comfortably warm. We had that discussion several times and I lost each time. So.....I did find that turning on the fan only on the furnace helped circulate the air, therefore helped a bit. We had heated mattresses and they were wonderful, but just increased the temp difference between inside and outside on the bunkend. The Hypervent, although it appeared to be the perfect solution, only helped in keeping the mattress above the moisture on the deck, so it stayed dry. We still had a morning routine of lifting the mattress to check for moisture and just wiped it dry if needed. We never tried this, but have wondered if some sort of temporary skirting that would surround the bunkend - like I've seen for storage under the front of a 5er - would be of any benefit. Might help to control the temp difference a bit. We moved from our HTT to a TT this past May and love our new camper, but miss the ROO. This subject is one you can count on several times during the fall and spring when there is so much temp variance. Good luck all, wish I had the magic solution.
