Lake of the Ozarks in Missouri.
My in-laws bought 14 acres for $2,500 at a Sheriff's auction and put three full-hook-up sites on it. We have been there a few times and just went again over the 4th of July holiday. The great thing is, we don't have to make a reservation six months ahead of time and we stay for free!
This land is across the road from a cove on the lake and they have a boat and a jet ski. They also built a barn with a washer and dryer, so it is pretty much the perfect campsite.
Deer, coyotes, and raccoons are frequent guests.
They have the Windjammer and our trailer is the other one, a 2013 Rockwood 2703WS. The area that is fenced off is their garden. Farther up the hill, they grow watermelon and cantaloupe.
