The only safe heaters for inside the cabin are electrics, period.

Yep, clear and simple.
I'd have to agree on that one. Generators are fine but not at night and most parks have hour limits for good reason.
While I do have a Honda 2000 gen, I don't like to use it as it is noisy etc. I did get a big old 100amp AMG? (whatever they're called) battery and park it under the little side table. I plug it in to a 12v socket and use that for battery power. TD battery is used, as is the propane on TD tongue, as a backup.
The generator, if need be, would be to recharge the big battery during the day so as not to disturb as much.
Still, with long johns, a big thick down comforter and an electric 12v heat pad, I'm not seeing a problem. I've only been down to 13F and while cold outside I was fairly warm inside.
I would NOT use anything combustible inside period.
I couldn't sleep at night while "Brain Noodling" all the ways it could go badly... heheh
Do it the old fashion way, dress warmly...
and the TD heaters???
I look at it like a fire extinguisher...
you don't need it until ya need it.
I have it an use it all the time. Rarely in the middle of the night, maybe 5-10 times in 6 yrs...
