At Hershey, dealers will look at your coach and work numbers as a trade. They also sell the coaches they bring to the show; they place "sold" tags on them when purchased. These units do however remain at the show for others to look at and walk through. I personally wouldn't want thousands of people walking through my unit, but that's just me and my OCD problem maybe. Purchases other than these end up getting shipped to the dealerships themselves wherever they are from. They do not allow units to sit for sale in the lot for the duration of the show.
All units there are new. Dealers bring no used with them and there is no used section for the gen public to offer for sale. It would be awesome if that could be done but I'd be hurting their sales I'm sure.
it is a great show though but plan on 2 days if you want to go through all the units. Wife and I only looked at haulers, if it wasn't, we kept walking.
