LSU vs Florida Tailgate

Posted about this a month or so ago with little response so figured I would post again. Bringing an RV up to Gainsville for the first time, and I am looking for some advice. I know it is first come first serve lot, but I have heard conflicting stories for WHEN they open the lot. University says 6 PM Friday, but others have said they let people in ealier and it fills fast. Anyone familiar with Gainsville tailgate scene?
