Are there Motels in the area up there? If so, they will be a LOT cheaper to sleep overnight at.
I have slept in my van 2/4 weekends past...
I park in a 24 hours Timmies lot ( not too close to the store).
Sleeping bag or a good down filled comforter works for me so far... The one night the temp got down to -3 and my head got a bit cool... but hey,,, as soon as I covered it up with my spare jacket, I was fine again.
I am also considering a bed in the back of one of my work vans for fishing....
here are a couple of good links to check out "van dwelling" ideas >>
