We are a big rig, a 44' fifth wheel and longer with a hydraulic motorcycle lift on the back.  We were able to fit into the state park.  In our two years of full-timing, it's the first time we've even tried.  Yes, some of the roads are tight, but I'm confident we'll be able to get out just as easily. 

Staff was very friendly.  The gift shop has some really cute / neat stuff in it.  They even have a little museum to walk through (for a small cost), which we haven't done yet.  (Arrived about 4, closes at 5pm (at least on Sunday.))

Site has a firepit, and it's a large pull through(those side pull throughs off the main road). Great water pressure. AT&T connection, 68ms ping, 18.46 down, 5.81 up. Good enough for my work.

Highly recommend Fish Tales restaurant, which you'll pass on the way in.  There's a Publix just a few miles away for groceries.  Pretty good wine selection!  Even a small, but sufficient, liquor store next door.
