Building a park from scratch, opinions welcomed!!!

We are full-timers and I can tell you we would never pay $47.50 per night. If we did, that would mean we pay $17,337 in a year for campground fees. Maybe others are different but we are not willing to pay that much to park for a night. For those wondering -- NO we do not usually park at Walmart but seek out Corp of Engineer, forestry parks, city and county parks and parks that give camping clubs discounts. We usually pay $8 to $20 per night with many being full-hook up pull thru sites.
