Traveling I-20 in AL and looking for an overnighter site? This is the place. Pull-in, park, walk to the drop box and pay for your site. All sites are FHU (30 & 50 amps) The CATV is basic and all channels (about 20) are clear. We always get in there early, so I can do some fishing. Never got a big one but always catch one or two nice ones. Never have tried to stay there during a NASCAR racing weekend but have asked and all say it’s always full-up all week.
We've used this RV Park about 6 times. It's easy to use and most sites are level or close to it.
Here a couple of pictures of the overnight section. The link is active and has more detailed information.
