Shows are for looking at, sitting in, and checking out what is where so you can decide what make and model you want. Once you have the make and model you can do a lot on the internet. Search for that make and model. It doesn't even matter if it is half way across the country. The money you save will be more than the cost of having it delivered. You can save thousands over "show special" prices. And by going to a one year old leftover you can save even more.
In 2010 we went to the Hershey show to look at Open Range 5th wheels. The show special on a 2010 385RLS was $60,000. I did an internet search and found a 2009 new in Indiana for $36,000. I gave the dealer I was working with at the show a call. I wanted to give them a chance. I knew they didn't have a 2009 and was willing to pay a little more for the 2010. The best they could do was $48,000. Yes that is $12,000 better than the show special price. And still $12,000 more than the one in Indiana. Delivery from Indiana cost me $600.
I have recently seen the same 2009 trailer advertised used for the price I paid for it new in 2010.
