I've only full timed through a winter in Alabama, so you might just discredit my opinion...
I have an 80s 34' sovereign
and a non functioning furnace. I managed to negotiate a lot in a rural park on a river bank for about $250 a month with 30amp electricity included. My trailers power was wired to where I could run the electric heater element in my roof AC, an electric ceramic heater in the front of the trailer, and another ceramic heater in the bedroom area and have them on individual circuits running full tilt without even warming up the wiring.
I'd hate to see what sort of electric bill I ran up for that poor lady, but running just the roof heater kept it at ~65* with high 30s outside while I was at work all day and running all 3 heaters combined kept me and my dog warm through a few single digit nights. No humidity issues to speak of with that dry heat, and I kept standard 30lb propane tanks for about two weeks per tank running the 6 gal water heater for 10 mins before each shower and doing all my cooking on the stove.
The neighbors in the park were fantastic and I even paid one lady's $30 a month cell bill to have her come walk and play with my hyperactive dogo-Dalmatian mutant dog everyday, finished my schooling, and saved up money to throw down on a nice Duramax 2500 with a 0% APR deal.
Now I have a house while the airstream gets a restoration, but I'm considering flipping the house and moving back into the airstream full time in a year or two.
I think the wood stove is a great dry heat source idea, but I've never stocked one continuously so it may be a hassle. I think a wood stove and a natures head might be a great recipe for sitting still through a winter, but i dont have any airstream experience that far north in the winter and neither do you. Make sure you're listening to the experienced ones here instead of just reading or probing for the answers you WANT to hear. Speaking about ideals is great but taking actions based on ideals instead of reality gets you in trouble fast. Just look at our government
