This has been going on for 20 years. El Camino in Palo Alto was lined with people living in RVs and working in tech. Same with Shoreline in Mountain View and many other major thoroughfares. Palo Alto and Mountain View cracked down and made most of them move on. Now there are lots along 237 in the Alviso area.
Yes, I have driven past the rows of RV’s near the Stanford campus. I would be happier with the situation if they zoned for more parks with hookups.
My wife and I joined the adventurous retirees and hit the road in a 34’ Travel trailer for 4 wonderful years. The time we were on the road gave our savings time to grow in the market and it did, thanks to no monthly payments. And many places do not charge very much for a four week stay. (And Elks freq;uently allow visiting Elks to stay at their places for free.)
