>>2383125The only problem with Wagons is your back is fucked after a while from being in them. Even my Toyota Hiace 2012 fully kitted out fucked up my back.
BUT if you’re just sleeping in it, ask yourself do you REALLY need the rear seats and passenger seat? If no, almost ANY car will do.
Apparently the best car for cold asf climates (minus the 4x4 capability) is a Prius since it sips fuel and can run the heater off the batteries.
As for 4x4, just get the total measurements from front (feet go here) to back of the car (head goes there) and anything will do imo.
I had a Mazda Speed 3 I camped in the USA and it was fine.
