Yes they have an RV lot!
They have a small RV lot with power, we have stayed several times in the last 3 months. Check in at the gift shop. cost at the time was 20 dollars per night You can call ahead and reserve as well. I have never seen it full when we have stayed there. Close to the casino entrance. Food is decent. they have a night club with live music and occasional shows in their bigger venue. Overall a good place to stay.
