My wife and I just purchased a 73 Argosy 24' that will become our "cabin" in the mountains of the Blue Ridge in NC.
We plan to gut and make our own green little home away from home on the weekends.
The plan is Solar for the lights and vent fans, a self contained H2o system that needs no black or grey water tanks. We use and love sun showers. We have a 12 x 12 shelter on the property now and cook with a coleman stove, grill and campfire. We have and use a cassette potty that we empty on the way home at a truck stop. More or less it will be a comfortable bunk house for bad weather. His name is Gus. More pics and details as the renovation begins.
