Best place to but a new rv? RV shows, dealer, rallies?

I like the "sale" price at the shows. It gives me a better idea where to start with negotiations. But when we bought ours last time, there was too much going on at the show, we were able to get started on negotiations but I had to walk away. We went to the dealer the next weekend and were able to talk one on one without all the distractions. At the show the dealers were too busy to hash out the details and besides they always will honor the "sale price" next weekend.
