I Actually did this for a few years several years ago after my wife passed. It helped me heal among other things. Off grid, freedom, teaches you to be very resourceful. I traveled all over the western US, Mexico and Canada. My rig at the time was a built S-10 Blazer. I did work though, as a kayaking and backpacking guide (which I still do part time) I would travel around...live out of my rig...offer my guide services...even spent a summer in Australia living in a tent and working as a kayak guide for 3 months, couldn't afford to take my rig though.
