Cold bed

[gitpicker2009]

We took the AF1150 out to our land in Nacogdoches this past weekend and it got down to 28 degrees. No problem for the coach, but it seemed like cold was literally seeping up from the mattress. I got an extra blanket and was still cold. Then I decided to put the extra blanket beneath us, and noticed a huge improvement.
I have the factory issued mattress with a 1 inch memory foam topper, so it's pretty comfy.
Is it possible that the cold is drawing heat out from beneath us? I figure that it's pretty thin under the bed. Any similar experiences or advice?

Thanks

Yup, heating mattress pads are great if you want to lay there and listen to the drone of the generator all night, or wake up to dead batteries...

You guys think that just running the pad a little bit before bed is going to solve this, but you don't understand that the heat transfer is happening any time there is a hot side and a cold side. The heat will be constantly sucked out of the bed, and will need to be replenished constantly to keep the bed comfortable.

That means the heating pad will need to run all night, which is not practical unless you have power. If I read my TC owner's club membership manual right, we are obligated to look down our noses disparagingly at anyone who would waste such a wonderful resource as a TC by staying in a c... c... c... campground.

The heating pad is on a thermostat and I can run mine for three nights without any problem. If you never used one you need not turn this into pissin contest.

Its all in your head. Try putting an extra pillow between the top of your head and the front of the cabover.

I installed Hyper Vent after discovering some mildew on the bottom side of the mattress, sitting on a fiberglass deck in my Hallmark, after winter camping. No condensation issues since then so the Hyper Vent is doing what it was designed for.
I like to think heated air circulating under the mattress warms it up, but with the blankets/sleeping bag overhanging the mattress not much air actually moves. The topper typically starts out below 40F and stays cold pretty long.
I might try a heated mattress pad under the memory foam topper.

We take an electric blanket. Normally preheat the mattress for 30 minutes or so, then if it is not real cold use it on top. If it is colder, lay on it and use a blanket on top.

When you're up here in snow country that would preclude camping for 8 months of the year. I'm not going to wait that long!:D

We just spent two weeks camping at 9800' in Colorado when the nitetime temp got down to 10 degrees a few nights. We set the RV thermostat at 40 degrees and we were warm.

40 degrees!! It’s at least 60 degrees at night, in the camper, or I will find a nice hotel to stay at. This RV thing is supposed to be about enjoyment and comfort.:B

Insulation under the mattress is good. Yet in really cold weather, convective heat loss in spring mattresses becomes readily apparent, in addition to the condensation of moisture in and under the mattress.

After insulating under the mattress using a foil faced polyisocyante foam, we replaced the original spring mattress with a closed cell latex foam mattress. While a bit heavy, it had no vapor permeability, good support, was much warmer to sleep on and wasn't so high that it interferred with closet doors opening over the bed.

During winter camping when recharging the batteries with the generator in the evening, we also turn on an electric blanket to pre-heat the bed. Makes for a very comfortable night when the outside temperatures are below zero.

An option on the new Northern Lites is a Hyper Vent mattress spacer. I don't know anything about them. Have you any experience with them? GeoBoy seems to like his.

Hypervent under the mattress, cool in the summer, warm in the winter and no mold/moisture problems.

Best advice I can give you gitpicker2009
is that it all comes down to this: the thicker the mattress topper, the hotter it will feel. I own a memory foam mattress topper and i must say that the wife and i love sleeping on it. Never going back to the usual bare spring mattress.

That being said memory foam are more likely to give you heat. On the other side, wool and feather toppers don’t retain the body’s heat. In plain English, in the winter, memory foam provide extra warmth. Which is what I know you need right ? :Z;)

here is a link to a good one. http://tinyurl.com/y7s4ftos
