RV parks in the bay area range from 40 to 80 bucks a night. One night.
My guess is if you are downsizing to an RV and you are the least bit clever you are parking on quiet streets and moving often enough to not bother anyone.
A friend has a habitual RV dweller on her street who occasionally gets hassled by the neighbours when he stays for to long at a time.
I have a friend who has been living in a trailer
towed by his truck for years. Sometimes he finds a cheap
place to park for say 250 a month, but often he is shifting around. He likes to park near parks so he can run and enjoy being outdoors.
Himself lives aboard alot, usually 5 or 6 nights a week. But we have 2 boats so with 3 days each he is ok.
