There is something up with BB website - the heated batteries are normally ~ $1000 not $2000. The other batteries don't need a switch - they only heat when it is both cold and they are charging, any of them will work in the situation you describe.

You can also just mount regular lithium batteries inside the camper and use your furnace to warm them up. Or add a cheap heating pad to the batteries. This is not the unsolvable problem that folks make it out to be.

So at -20 to 0F I can use the batteries to run the furnace to heat the batteries? Apparently I got some really crappy info from Battleborn last winter.

Then there's the price. Even $1,000 for a heated Battleborn is too much for only 100 ah's.

I'm good for now with 260 ah's of SiO2 batteries, but just want to give accurate advice to friends. I'm currently adding three 100 watt Renogy panels to the existing 170 watt panel on the roof. We have a site in a great campground on the Root River. It seems I'm spending just as much time explaining what/why to neighbors as time spent adding more solar to the roof.

Enjoy,

Yes you can.

It sounds like your batteries are within the heated space, then you don't need heated batteries, which brings the price down to ~$500 per 100Ah. Or you can add an adhesive heater (about $25) to a regular battery to make it a heated battery if you want.
