Niche question, I realize, but I'm going to lend a bit more weight to responses here than elsewhere.

This winter did not go as planned, and as such, I find myself still in Texas, which is bad enough, but I live in a tool van, and even with 2" insulation, it's a metal box exposed to the sun. The forecast for the weekend is 97 all three days, so that reminded me of a friend's suggestion to look into this site.

Ultimately, what I'd like to know is whether it's worth the annual upfront cost to provide a service (unexpected), as while it could get me in air conditioning before leaving this hellhole, it would also be pretty badass to be able to travel the country with indoor plumbing and appliances as my anchors.
