I keep thinking RV's and the Tiny Homes "revolution" will be a way to help the homeless problem. Tents are difficult to live in, and lack privacy.
The issue will be where to park them, and how much service needs to be available for them. Space is available, but away from the cities.
There are certainly enough of them already built, used, but, new ones are not any where as expensive as our area's ridiculous housing phenomenon.
