Condensation Under Mattress

Well, we'll leave tomorrow for the weekend. Temps for Thursday (Thanksgiving) and Friday Morning are forecasted to be low to mid 30's.

• Ceramic space heater is ready
• Furnace has been tested
• 'space blankets' to put under the mattresses
• Popup gizmos for on top of the bunk ends
• Reflectix inserts to put in the bunk end windows
  

I'm about as prepared as I think I can be to keep the condensation at bay

We'll have 4 adults and 2 small children sleeping in the camper so I'll make sure I get plenty of air circulation going at night.

Thanks for everyone's suggestions. I'll report back after the trip.

Happy Thanksgiving everyone!!!

Air mattresses are chilly in an HTT.
We used to always elevate the mattress during the day to dry the condensation. Our solution was found with a proper 10" pillow top mattress. Comfortable, warm, and no more condensation.

This may be my next option. Thanks for the link

if you buy some, please leave a review here on if it works.

Hi,

The solution is to keep the temperature of the material above the dew point.

OK...so I'm going to get a couple of these to see if they help:
Solar Blanket

Now..here's a question. Silver side to the mattress or to the deck?
I'm guessing it's silver (reflective) side to the mattress so as to keep the temperature differential away from the deck.

I know..I have a 50% chance of getting it right.. :)

these are the generic versions of Popup Gizmos. many use them instead.
i've tried both sides on mine with limited success.
i still get condensation but i think with the silver side down, you get it between the bunk door platform and the solar blanket. and silver side up gets condensation between the solar blanket and the mattress bottom.
but i'm not sure since i now just use a wool blanket instead. problem is that the solar blanket doesn't allow for air to move, it traps it. while the wool blanket does allow for some.

I tried air mattresses and found that the air in the matress is as cold as the bunk end. So we froze the weekend we had the air mattress in use. This was a weekend the temp was right around freezing at night. I couldn't believe that mattress never warmed up, the following night we tried an extra sleeping bag between us and the air mattress which helped a wee bit. Ended up coming home a day early

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.
