Residential frig below freezing in very cold weather?

I agree with DrewE, I'd load up the fridge just before you pull out. What's the worst that could happen? Things in there get seriously "chilled". :B

Once you get rolling your going to need some kind of heat, the temp inside should rise at least a little unless of course you kick the heat on while rolling making it a moot point.

Good luck, enjoy your adventure!
