I've seen them at a few college games I went to. I went to East Carolina at West Virginia a few years back, and saw several then. It looked like the people got there the day before the game (I was there waaaaay early, and they were already there set up and with full trash cans). They probably had a few beers the night before, slept there and got an early start on game day. If you find a place that'll let you park overnight, I can't see way you WOULDN'T want to take your RV. Sounds like a blast to me!
