RV living to avoid homelessness
https://coloradosun.com/2023/09/29/can-rvs-help-solve-homelessness/
This talks more about staying in an RV park or similar facility. What I see on my daily walk is a couple campers / RVs that move from time to time up and down a side street in a commercial area.

I will also guess there are far more than the 6K or so this story talks about.
