Nomadland the book documents this for a lot of Americans surviving in the brink in the aftermath of the 2008 crash, turning to living in vans and RVs, a less glamorous version of van life, barely scraping by and eventually bad luck or circumstance of some kind of another just crushes individuals. Even in Silicon Valley just a few streets from Google HQ in Mountain View on Longhorn and other streets there are several blocks filled with RVs of folks I assume like the ones in Nomadland. https://maps.app.goo.gl/KQY2AWL2sNfGem44A
