I have noticed that also, people living in campers.
Just a couple of years ago, trailer parks had just single and double wides. Now I see a lot of smaller, weekend type trailers that are someone’s permanent home.
Other locations have noticed— rental storage units. At one point transiting from one location and picking up furniture, noticed a guy every night coming in at midnight, parking his car in front of an outside unit and locking himself inside— to spend the night. Saw him next morning early AM taking off to whatever work he was doing. This is the reality of those who may be living off EBT and welfare to some extent— or are proud and working and trying hard to live, but an alternate hidden economy.
