Even with destination campgrounds filling up, people need a reason to stay at your location. I choose my locations on three priorities:
1) If I am going to stay for a while, the place has something for me to do. Lakes, fishing, small amusement parks have been draws. I.E., you are creating your own little Disney World. These places can be off the beaten path.
2) The place is convenient for an overnight stop and has the facilities a traveler needs. These include power, water, sewer hookups, LPG sales, showers, and a convenience store stocking also RV needs. A small restaurant, on premises or nearby, is a plus. Location is preferably within a few miles of the highway I'm traveling (not necessarily an Interstate, but most of RV traffic in the most densely populated parts of the country will be on Interstates).
3) The place happens to be on the highway I'm traveling, about the time I need to stop, and there is no place else within a couple of hours of additional travel. I am still looking for the basic amenities, but with no alternatives will do without the showers, restaurant, and store. I've parked behind gas stations or motels, offering hookups, on such occasions.
You can build the greatest RV park in the country, with respect to services and amenities, but if it is not convenient to travelers, or has vacation destination drawing power, you will not have many visitors.
