My BIL found himself living in the front seat of his truck (not by choice). He has a health issue which requires him to sleep on his back with his feet elevated - not something he can do in the driver's seat. I picked up a 5 x 8 enclosed trailer, and with the support of his family and a large collection of things left over from previous builds, I put together something that he can live in for quite a while if he chooses to. He lives in northern Louisiana where there is not a lot of BLM land, but I did find 4 free campgrounds he can stay in for 14 days at a time. They have restrooms (no showers) and drinking water available. Right now, a contractor he does work for is allowing him to park on a job site, so he has a very short commute and access to shore power. Building this has me thinking about building more of these (on a lesser "amenities" scale if I can figure out how to finance them. Thought some might find it interesting.
