Been there three or four times. It's a pretty impressive place. If you are just looking, it's a great resource. If you are buying, you better do your homework beforehand, or you're in danger of getting really screwed. One year we were serious about a specific trailer, and sat down to get a firm price on one, at one of the local mega-dealers who had a big presence there. The salesman proceeded to treat me, (with decades in the hobby, and 6-8 RV purchases already) like a moron who was waiting to be robbed. He started by writing the list price of the unit on the sales order, but quickly wrote a new order up, with a 20% discount, when I questioned if he really thought I was dumb enough to pay list for a travel trailer? Five minutes later we got up and walked, when he asked for a deposit to "hold" a unit that we, #1, hadn't even come close to agreeing on a price for. #2 Had never seen, and #3 they couldn't find, and was "probably, definitely, supposed to be" at their dealership, down the road on I-4. He tried to tell me that we couldn't leave the show, and drive to the dealer to see the trailer, unless we gave him a deposit. He then called me for the next YEAR, hoping to do business.
Bottom line? The show can be a valuable tool as you shop for an RV. In many cases "show discounts" are a joke, and aggressive, even unethical, sales tactics are not unheard of. Have fun ,but be careful.
