The other issue here is one of available housing. Most california cities are under extreme pressure to increase housing supply, an RV lot isn't going to house as many people as a condo/apartment building. (I honestly don't even know if an RV park counts towards overall housing supply) Though the stacks idea is interesting ;-) There's a few buildings going up in the Oakland Temescal by Rad Urban which are modular its been cool seeing units with kitchens etc already installed getting stacked up into a larger complex. https://radurban.com/ https://radurban.com/
