Stayed at the TA outside of denver after me and the dog started getting altitudes sickness up at Camp Dick ~11,000ish? feet. they had 2 lots, 1 for campers and 1 for trucks. I ended up talking story with my “neighbor” and most of the cars and campers were locals living there. it was loud but i got my nap and then on my way. I have stayed at a couple rest stops for a quick over night nap. I’m not dick and set up camp… Just pop the top and go to bed. Nobody has bothered me.
This has been somewhat useful:
