That article has been reported on in the recent past. Yes, it's true that more cities are banning people from living in their vehicles. I'm guessing it will get worse before things get better.
From what I can tell, cities are particularly extra interested in banning "over-sized" vehicles that fit a certain height and length criteria. That pretty much means any Class A or Class C RV vehicle due to their extra size.
When I was first searching for a van, I thought maybe I made a mistake in not getting a taller hightop model. But now I'm actually glad I got a low top vehicle instead, because that means city officials don't consider my vehicle an "oversized RV", which it isn't anyway. Plus my van is standard length instead of extended, so that also is in my favor.
For those who have a Class A or Class C RV and do city dwelling, I feel bad for you. It's only going to get harder and harder to park in city streets.
I feel that with all the "bad press" from RV dwellers being in the news in a negative light, that can't help but to spill over to affect me as well. Makes my life that much harder too. So far I've been dealing with it and making it work.
