Yes. You put 2 nuclear blast furnaces under your RV, and wall up the undercarriage with electrified depleted uranium armor.

I lived there for 9 years, getting ready to go back. I found this because I am considering the same idea. My friend in Anchorage, who used to work for me at Eielson, said he heard someone who had done this, but he thinks they 'cheated', i.e. winterized the RV and used it as a dry cabin in winter.
Anyhow, I would love to hear any experiences the OP or anyone else had trying this.
EDIT:
Still not thinking this is the best idea, but just thinking out loud. The USACE Chena Lakes Recreation Area is open year round. The fees are waived in the Winter, which is, needlessly say, most of the year. Also, disabled vets get a free camping pass.
I would still love to hear from anyone on ingenious ideas for keeping pipes from freezing. My Anchorage friend, whose RV I stayed in last winter, had to wrap heat tape around his pipe after his washing machine created a lake in his carpet...but I don't think even the tape would work at 50 below.
