I agree. We spent thirty years in motorhomes without a thought to reservations and the last few years have just not been as much fun because of planning required and certainty of time and place. Most of those years were spent in Class Bs which gave us much more flexibility than our PC (which we love). We prefer national parks and forests. Recreation.gov is a game to get a spot that I really don't enjoy playing but of course I do it anyway because we have little choice.
It will be interesting to see when the COVID crisis is in the rear view mirror in a couple of years if the current RV craze continues without abatement or correction.
