I had a different experience buying at a RV show. We did go the last day, and took our time looking around. We walked the whole show, and found a TT that we liked, with some changes. We also didn't go for "show price" just because it was listed as such. We sat in the rig, and wheeled and dealed with the salesman, and then the factory rep. They were shutting off the lights in the show closing up, and we still hadn't signed. Finally the salesman came back in with the price we wanted, and the changes we wanted. It worked out great, and we picked up the coach about 4 weeks later, right off of the assembly line.
It can work for you, as long as you keep your wits about you and don't buy the salesman rush job.
