Very well said Colleen.
It is definitely not as easy as I am making it sound but you made a very key point, which is, you have to find a way to do it better than your competitors.
Whether that better experience is more privacy, more amenities (sauna, water access, hiking trails, etc) or more uniqueness compared to a basic KOA, there has to be something that will make people choose your site over another.

This is a niche in the camping world. Private campgrounds have existed for a long time. Backwoods camping is available in alot of areas without a campground and there is a huge network of national and state parks you can camp in.
You have to think about what isn't available or you could offer in a better way. Off grid cabins with outhouse, privately owned, not really airbnb material might do well on this. Camping sites near to parks that frequently get overbooked. Offer a better experience with a small number of sites. They would come to you to be more out of the way but not hike a mile to get there.
RVs don't need all hookups if they aren't staying for a long time, most want electric. You do need better road access for RVs. However your tent campers will want to be separated from RVs.
