Not that I see long periods of -40, but the plan is to be able to drive it anywhere/everywhere, and I do see -40 at least 3 times per winter.
I've got a lot of questions so I think I'll read a bunch more before asking them, but if people know of good builds to read through for winterized skoolies I'd love to be pointed in the right direction. Right now my thoughts are for a bus without shore power, and I'm open to suggestions regarding heat, insulation, windows, roof-raising, basically everything.
Y'all have been fun to read, hopefully you're just as fun to interact with
Oh a little bit about me: 29 y/o auto mechanic/landscaper/university student (it took me 10 years after Highschool to realize I should get some higher education). I play drums, and like being eco friendly.
Welcome to the forum.
At -40 (I won't put F or C, because they are the same), you have some very specific problems.
Insulation, insulation, insulation, then heat.
You will need to insulate the crap out of it. Roof, walls, floor then delete as many windows as possible, then get everything possible inside the bus.
If I were doing this I'd be looking for a rear-engined bus with pass-through storage bays. I'd put the tanks and plumbing in the bays and insulate all around the bays.
Then I'd want a big-ass diesel-fueled heater or two (Eber, Webasto, Tapan), and I'd run one of the hot-air outlets right into the storage area. If you have two units, the other three outlets would heat the bus.
I'd want foam-board fillers for all the windows you keep, for overnight and days you don't move. A large battery bank and a generator to charge them when shore-power wasn't available. Keep them in the storage bays too, and keep them above zero.
There isn't an RV made that is designed to live in at those temperatures (not even the 4-season ones), but I guess we have the advantage because we can spec to our own needs.
This would not be a cheap build, simply because your life could depend on doing it right, and I've only scratched the surface.
