I know this is a serious topic, but if you are open to the possibilities it is not too hard, out here in the empty lands, to find a place that will not likely ever be competed for. For example, I would be quite surprised if this reliable spot of ours is ever filled up, or even if anyone would ever go there at all: 38.55592, -117.2275
If people need infrastructure of any sort, then the competition and dumb behavior will always be there. It really boils down to avoiding popular places at popular times. On our most recent trip we thought about dropping into Goblin Valley State Park -- it was not surprisingly full up. However we drove on a bit to a lesser known BLM campground and of the thirty-odd sites only two others were occupied. This is the campground where we noted, on our walk around, two husky bearded young men in their late 20s or early 30s camped across from the upper pit toilet bathroom. Later, we observed with some surprise, the same two fellows DROVE about 100 yards to the lower bathroom which had flush toilets, presumably did their business, then drove back to their campsite. We had occasion to use both facilities while camped there and can't say the pit toilet was anything other than clean and well supplied.
Well, happy camping y'all. The reason you have a camper is to get away from the maddening crowds.
