There is a very nice and new State Forest cg off SR 337 in between Bronson and Newberry. Dry but has water on site. $10/night but I think you can get a pass online at the Florida State Forest site. The sites are all pull thru with lots of room in between sites and a fire ring and picnic table at each one. They are in open shade. It's in the Goethe State Forest. I have never seen anyone camping in it and only occasional horse trailers parked while they use the equestrian trails. There are trailheads leading to about 10 miles of good hiking trails. Newberry is about 10 minutes away and has a supermarket and hardware stores. Gainesville is about 30 minutes.
The National Forest around Ocala right now is heavily infested with snowbirds so I doubt you'll find much solitude around there. Not until the snow storms stop up north which they show no sign of doing right now.
