Why not buy a nice trailer? Its already set up for electricity and water etc.
If you have to move its on wheels.
If your stuck herding reindeer buy a yurt.
I actually signed a contract with the Obama government to herd reindeer so I'm SOL already just wanted to be comfortable. A trailer was another option we've been discussing but Yurt's are just what we've been leaning towards. We're going for the Genghis Khan look.
