Not free anymore, they charge $10 to park now. I knew something was up when we rolled in and there were no RVs or vans parked in the lot. You have to check in with security in the casino.
Very quiet, flat, and seems pretty safe. Signs say to check in with security before staying the night. Many other vans / rvs parked and bad window tags from checking in - security didn’t give me one but I didn’t have any issues.
