@toedtoes: It doesn't necessarily have to be streets. I created the post with an open-ended destination, seeing if people on this forum had experience with this sort of situation.
How long? As long as we live in the Bay Area.
If the RV breaks down, Airbnb time until we get it back from the shop.
We have one other car at the moment.
@udidwht: That shouldn't be a problem. We can always the move the RV after 96 hours.
It's looking like I should just put an ad up on Craigslist seeking someone who would let us camp out on their property in exchange for a daily or monthly fee.
Does anyone else have any more advice?
