I don’t think there’s a real stigma for people who can afford to rent an apartment but live in an RV... it’s almost hip at this point. However I don’t think it’s as practical as you think. Addresses are very important.
Well, I should have been more up front that for the record, I lived and surfed for 8 months out of campervan I built myself in Australia. It was pretty great. I didn't really have any major issues, it seemed really practical to me? But I didn't really have a day job then.
