Howdy. Are you familiar with RVPARKREVIEWS.COM? There's lots of great info there. We haven't been to Tunica, but we like the Hollywood Casino RV Park in Bay St.Louis, MS. The campground is very nice, paved and level sites, with a clean bathhouse. Sites are not too close for comfort, with picnic tables and BBQ grills. They also pick up garbage at the sites twice daily and there is a shuttle that runs to the casino throughout the day and evening. (Though the casino is in easy walking distance across a huge parking lot.) We like the casino buffet, too.
