12 volt electric blanket

Don't cut down the 12 volt electric blanket until you've tried it. We have one and it comes with a built in timer for 20 minutes or 40 minutes no way to leave it on and drain your battery. It is great, you can plug it in to preheat your regular or flannel sheets for 20 minutes or if truly cold set it for 40 minutes and drift off into dream land and it goes off automatically. We also have a Memory Foam Mattress topper from Camping World that we placed under our Sleep Number bed and it makes a great insulator under the air bed. We camp in cold country a lot and we are nice and comfy. I have wired in a switch for running the 12 volt Electric Blanket.

Happy Campers

That's what we use in colder weather. We have two that zip together to form one huge bag.

No need to go hi-tech or hi-$$. Get 2 "camp bags", not interested in how small they compress for carrying. In very cold temps, throw a heavy blanket over the bags.

I have tried a memory foam mattress in the past, they go hard as a rock below freezing, I mean very hard, and they are very cold until your body heats up the mattress, and that takes a while.

Or how about getting a memory foam mattress/topper and you won't need a 12v blanket. (speaking from experience, they sleep too warm for me)

lay on top of a down and cover w/ one and ad additional comforter if necessary .... grey tank open, black and fresh never more than half. use 12V tank heat pads every so often. worlds great and no worries

I bought a 110 volt AC double bed heat pad that uses a converter to produce 18 Volt DC. The pad uses very small wires, you do not feel it, and using DC current is supposed to be less danger than a 110 AC. I tought it would work directly plugged in 12 volt, while producing less heat, but it did not. The controler just tip off.

So I bought a converter to up the power from 12 volt DC to 18 Volt DC. It works, I think it uses less power to go from 12 DC to 18 DC. Otherwise, I have to use an inverter to produce 110, then plug in the converter provided that convert 110 to 18 volt DC.

Why not use an inverter to operate a 110v. queen ?

or as suggested, use two 48's with individual heat control.

3rd option is to use two 36x60 12 v mattress pads. avl from tractor trailer supply companies .

Our solution: 110v queen mattress pad off an inverter to warm things up . Once that's done, our King size double sleeping bag takes care of business better than anything we have ever used. Most of the time its too hot and it uses no power. We bought two king size top sheets and had them sewn together as a washable liner.
We found the king size to offer lots of wiggle room on top of a queen mattress. http://www.rei.com/product/828229/the-north-face-dolomite-3s-sleeping-bag-double

Just get two of them - problem solved... Better yet just get two twin size 12VDC electric blankets...

You also need to know how many DC AMPS does the 12VDC TWIN SIZE electric blanket draws from your 12VDC battery...

You will need some pretty substantial batteries if these draw 15-20AMPS each in addition to a very good 12VDC socket setup..

I am not a good fan of 12VDC appliances due to the high DC currents involved.
