Hmmm.
I think I've already met this guy, or several dozen or more like him.
Stealth camping wears out real soon for a full timer, as it requires moving constantly, concern with dead batteries, full or empty tanks that require dumping and charging. Particularly in a small unit with limited capacity.
Wheres the cost saving or the lifestyle freedom when so much of that life is restricted by those concerns?
Off grid living still requires fresh and waste water, debris handling. Those are not free. Hunting down free dump stations can cost more in time and fuel than a campsite.
For the OPs wishes, As a financially independent person certainly he can afford the time. Jack Kerouacs 'On The Road' could be a fine read
