From July '12 to March '13 I lived out of my van in Utah. The winter was cold, however with kind friends allowing me to park in their front yard and plug into some electricity I survived with a space heater. It wasn't bad. I made some insulation for the windows out of some thin insulation sewn into fleece fabric squares cut to fit the windows on the van. It kept me much warmer, the addition of a front cab divider also made it extremely stealthy, and nearly impossible to tell anyone was in the van with lights blazing watching a movie.
It was extremely dry running a heater all the time. I purchased a personal space humidifier to restore balance to my environment. Cold winter with lots of great powder days.
