I love wood heat, but more and more I'm thinking that an inexpensive vevor diesel heaters and a 12 volt battery might be a nice alternative option, save space and effort and you could run it all night if you wanted to.
Can't beat wood heat. If you run into real bad weather and have to stay put for a while you may very well run out of fuel / battery power. I'd never rely on something like that for my primary heat source. makes for a cold stay when you run out of fuel or run into electrical /mechanical issues at -20, -30 & -40C!
Likelihood of running out of solid fuel to burn is slim unless you're above the arctic circle.
