Overnight spot around Dyersburg, Tn to Jackson, Tn

Here in Jackson, we see a lot of people overnighting at Sams club next to Walmart. Not enough room to stay at Cracker Barrel. At the Sams, there is a big lighted parking lot on the right end of the store, easy in, level parking, and enough overhang so putting a slide out is no problem. It is usually empty except for the RVs overnighting there.
