One blogger I know who is a full-time RVer was staying a lengthy period of time on a camping site on a lake managed by the Corps of Engineers (COE) during the shutdown of campgrounds in 2020 because of the high infection rate of Covid at that time. The Corps did not make them leave when the Corps was asked if they could stay, and they were even allowed to extend their reservation. Full-timers had a bad time during that period because they live on the road, have no "sticks and bricks" home to go to, and the campgrounds were shutting down during that high infectious period.
