I have never purchased from a RV show and would not unless I knew exactly what I wanted and what I was willing to pay. I would think you would be able to go the dealer shortly there after and get the same price. There are at least 4 rv show in WI spread out over the winter months offering "best prices of the year". A salesman at the show did say they get rebates from the manufacturer on trailers they bring to the show and that is how they can discount them. He also said there was more room for negation on price listed at the show.
