    Just received 2 "World's Safest Warming Mattress Pads" from Cozy Winters. The claim is that 12-volt heating coils are safer than 120-volt. (It still plugs into the 120-volt outlet, then converts to 12-volt). I'll try them out tonight (down to 28-degrees) and see if they produce enough heat to warm the sleeping bag.

    Anyone else using these?

    Let us know how they work!

    We have our winter campout with Indian Princess in January and although it's not nearly the winter most of you experience, it can be cold at night. A 12 volt heater pad to augment our electric heater might just do the trick!

    I too am interested in knowing how these worked out.

    I haven't tried this particular model, we use a 12v heated mattress pad from Sears and it works great since most of the cold air comes from under the bed.

    it's really not recommended to use the heating pads in conjunction with electric blankets

    at least that's what mine said on the label ;)

    "Driveway" camped last night, temp dropped to 20degrees. Here's my set-up: Holmes "Whisper Quiet Twin Ceramic Heater" (HCH 4953..Walmart $38) pointed right at me.
    12volt mattress pad (Cozywinters.com) on high.
    10-year-old Kelty "Ridgeway" (+20f)(Costco) sleeping bag.
    "Popup Gizmo" under the bunk-end mattress, foil side up.

    Inside camper 51 degrees, outside 20 degrees.
    Mattress pad, on hi, worked, but barely kept up, although I made it work hard, as I was in the sleeping bag. Tonight, I'll try a flannel sheet over the pad, and sleep directly on that.
    My nose was very cold, but otherwise, it was more than adequate. If my wife had been with me, I'm sure it would have been better.

    My concern now, though, is folding the camper up in sub-freezing temps. Vinyl windows are rather stiff. Any thoughts? I'll also post the same question elsewhere.

    Sounds like the trip I had a few weeks ago! Didnt have a thermo to see how warm or cold it was in the pup, but my nose and exposed ear were COLD... Also had the heated mattress cranked, an electric 1500w heater aimed at us, and the far bunk curtained off being that nobody else was with us.. It was WARM compared to outside, but the canvas seems to let in some cold... I dont have gizmo's or anything yet, but plan to soon...
    As for folding it up, crank that heater for a while, with the top of the end bunk screen undone, i mean barely undone, so it can vent some, and id think you should be fine to fold it up then. PLUS, it will be somewhat warm due to the heater having been run inside.. Good luck, let us know how it goes!

    Flip the gizmos over. ther silver side will reflect heat into the bedroom, not send whatever heat bouncing off the roof. We have found this out on our own.

    Hey mostlyok,
    Thanks for the input.
    In cold weather, you put the gizmos on the roof of the bunk end, foil side down? I thought it would do more good under the mattress, foil side up.
    Have you ever compared both versions? Anyone else have a thought on this?

    If you build your own gizmos, you can actuall build a "sock" that goes all the way around the bunk end, secured with velcro.
    (gotta take some pix of this. I keep telling me and telling me.)
    the thermostat of a 1500 watt heater will actually shut it off even when the temp's in the single digits and have never needed an electric mattress thingie. As for the canvas/windows being stiff, if you make turing off the heater the last thing before cranking her down... not a problem.

    your mattress and the bunk itself are a lot thicker than the canvas, so I'd definitely use the gizmo over the canvas

    3200 mile trip from VA to TX, temps down to 25f at night. Heated mattress pads, with heated blankets, were extremely successful. Here's what we did.

    Set up camper.
    Fire up propane heater, turn on mattress pads/blankets, 1500-watt space heater.
    Go to c'ground facilities to brush teeth, etc (plumbing in pup remained winterized, except for Thetford).
    By the time we returned to pup (maybe 10 minutes), inside toasty warm, with bunks warm as well.
    Turn off propane heater...not needed after initial warm-up.
    No problems folding pup. The vinyl windows complained a bit, and I was very gentle with them, but never felt threatened.
