That whole area is pretty sleazy. Don't know about Tom Sawyer, but it does get good reviews. We broke down last week in West Memphis and limped up to the Memphis Area KOA. It's at Exit 14 off I-55 just north of I-40. Since we didn't have a reservation and it was an emergency, we stayed two nights in a W/E only site with 30A service, in the front, close to the interstate. Surprisingly quiet, even with the traffic noise. Very clean, nice folks running the place. Full hookup sites are in the back and closer together but still pretty good for the price.
