I live on a canal boat in London (http://everythinginthesky.com/tagged/boatlyfe) that I'm looking to do up in a similar fashion. It's a long road, though - I installed solar panels and a basic 3G wifi setup, but it's all been delayed while I have it stripped back to bare metal and rebuilt. The nice part about the boat is that the arrangements for moving it / living on it are a bit more formalised than I imagine this is and are part of the lifestyle. Still, this seems like a much more mobile solution. Good post!
