I know I am late to the party, but was doing a search and came across the post. We also have a reserved spot at UF for the Florida games which allows us to arrive on Friday and stay til Sunday. "sweet" I have been to NFL football games in some big rigs, Jags, TB, Miami, Dallas, Atlanta of the all those I would only have concerns with Atlanta and Jacksonville. Doable, but tight...
Having only visited Texans (HRG) stadium in a car I would say "MAYBE".. really depends on where they put you, but I think its possible. Do some homework, drive it a before if you can and go for it..
Now if you were talking Texas stadium, aka ATT, aka Jerry's World!! No problem..... **** they might have inside RV parking in that place!
