Just an FYI: I asked Escape about these heaters yesterday, and the response I got back today is that they're 10A each. So, 20A/240W for the pair of them, while they're running.

That is exactly why they should only be used while plugged in, so that your 55 amp converter can supply the power otherwise 5 hours will kill a set of 6 volts!

Also FYI, the single 12v battery is rated for 98Ah, and the dual 6v is rated for 232Ah. Not sure how that "rating" corresponds with real world use, though -- is that the amount you can safely get out of them before recharging, or is that the total capacity before you run them right down (and ruin them? I know these are deep cycle batteries, but how deep is deep?)

On a sunny day in good exposure, your solar might give you ~80Ah per day. Running your 20A worth of heating pads for 4 hours is enough to use all that up. Add in the power you bring with you (232Ah in your dual 6v batteries) and if you need to run the heating pads for 8h/day to keep things warm enough, you've got about 2 or 3 days off grid before the numbers catch up to you. Obviously if it's colder to run out of power sooner, and if it's warmer you last longer.

How cold does it have to be before you need to run the heating pads for 4 hours/day? I have no idea...

For what it's worth, I've decided that for our camping style (occasionally getting caught below freezing when camping at high altitude in the shoulder season, but never planning on camping in the dead of winter) we don't need the heating pads. And, without the heating pads, we don't have any large power draws so we don't need the dual 6v batteries either.

I'm not so certain about the need for the dual 6v batteries, but they're easy to retrofit after the fact. The heating pads would be rather difficult to add in after the insulation is blown underneath...

Here is a good source to understand your 12v system and batteries
The 12volt Side of Life (Part 1)
http://www.marxrv.com/12volt/12volta.htm
you only have available 40% of your capacity, thus with 6 volts around 100 a/h of use
I'd only use maybe one hour off grid, just enough to melt. With the foam, I have camped down to 10-15 degree(F) without the need of tank heaters, but I have them in case I ever need them. They only come on at 32 degrees maybe less since they are foam covered, not sure where the thermostat is located on them.

I was under the impression that the little optional window above the sink does not open if thermal. Does anyone have an opening thermal version above the sink?

The sprayfoam option ( underneath insulation ) is applied in a manner that any parts that need to be accessed are available."

I can only answer for our 2012 15B. We added two small windows--both are thermal and both open.

The opening window is not thermal on the Escape 19, the fixed one, non opening is thermal. I'd rather have the opening one, works great in the rain, it is an awning style window. Can you verify it is thermal in the 15?

Hmmm... Just picked our 15B and all windows are thermal according to Reace EXCEPT the small swing out by the kitchen. He told me it is the same size as the one in the door but the door is thermal because it does not open.

Yes, that is the one weak spot in the insulation, a themapane window in an uninsulated door. I'm working on installing some spray foam inside the door's 2 skins, as soon as I can find foam that does not expand, I do not want to crack the door skin.
