I am a local and have not stayed here in my travel trailer, but have confirmed with the casino that people are allowed to overnight in RVs in their lot for free. At this time there is no limit on how long you can stay.
Dry camping only. No RV park on the premises. No water faucet or dump station. Easy access to and from I-75 but far enough away to cut road noise a little. Closest dump station is at the Cabela's off Liberty Way exit a few miles to the south on I-75.
