awesome, im really getting attached to the idea of living in a van myself, i dont have any dependents to take care of other than my dog so i think a van would be a great option for me, and personally i dont see why it would have to be a poverty thing as you stated, as for van farming, ive been considering potentially a roof garden if applicable to the situation and perhaps some vines along the sides to help with thermal retention in winter and cooling in the summer, plus a potential food crop
if you dont mind i may post up a question if one pops into my mind on specifics of life in a van, however the only potential downside ive seen so far (as far as how it works for me at this point in my life) is that i might not have an address of my own to have things sent to, but that is of
course possible to work around:)
