Where do you imagine you're going to park it? It's 2 hour parking in resdidential areas unless you have a resident permit (not that there'd be any available), no overnight parking in commercial areas.

A paid parking space will run you the price of a 1-bedroom in a sane region.

Then use an autonomous RV. As long as it keeps moving around, you don't have to pay for parking :)

Some Walmart stores allow RV parking -- not sure if there is a limit, or what the quality-of-life is like.

Mountain View's Walmart does not, according to this: http://www.walmartlocator.com/no-park-walmarts-in-california...

i don't know the Bay area, but can you maybe get a job at a company that has some parking spaces?

People have lived in an RV in Google's parking lot. Being on the campus all the time, they could save almost all of their salary.
