It’s pretty much impossible to go to a public campground these days and just tent camp, without being sandwiched between giant RVs. They block views and also, often, the sun itself, and they are constantly running their generators so they can watch TV or whatever they do in there. Brightly lit strings of poorly aimed 5000K LEDs are common at night, so if you wanted to enjoy your flickering campfire or watch the stars, good luck. Often they have a whole living room set up outside with artificial turf, a huge canopy, chairs, etc.
If I wanted to camp in a semi truck parking lot I’d go pitch a tent in a truck stop. Camping as many of us knew it growing up, is pretty much gone.
Public parks love these types of campers for some reason, so nothing will ever be done about it. You would think they would designate part of their campgrounds as tent only but very few do.
Can’t speak to private campgrounds, I assume it’s even worse.
There are some, and also dispersed camping, so there are options yeah. But official campgrounds used to be a nice place for families to tent camp, with easy access to restrooms and potable water, no longer really. I mean obviously you can go off-peak seasons and stuff.
