"According to our Bonnaroo dictionary, an RV is defined as any vehicle equal of, or larger either in length, width or height than an average 15-passenger van (230.8″ x 79.3″ x 82.3″). This means any oversized vehicle, trailer, towed camper or bus is considered to be an RV. (Important: A box truck is not an RV. It is a box truck and box trucks are not allowed.)
To gain entry, your RV must fit into a 20′ X 50′ space (including slides or awnings)."
Something tells me you might have issues with that... Calling someone might be easier when it gets closer. They're not always quick about emails, if they even answer at all.
