Is this generally ok to do? Just bought my tiny trailer and I'm curious about all the ways I could be using it. I'm not talking about camping in parking lots, just sleeping. Just pulling into a grocery store parking lot to use the restroom and sleep for the night. I'm thinking I'd want to do this on long road trips, where I wouldn't know exactly where I'll be stopping for the night. Or just heading out to the beach late at night for an early start the next day.
Maybe laws regarding this vary from state to state? I'm in Portland, OR so I'd be doing most of my camping in Oregon and Washington.
