When we bought our current trailer we ordered it through a dealer that was about 2 hours away. We had seen the model we wanted weeks before while camping in the area when we stopped by the dealer to get a part for our awning. We were just looking at the time but a couple of weeks later we went to a large RV show. Two dealers at the show were ready to order the model we wanted, we got quotes from them and then called the dealer we had visited while camping. They were willing to beat the show prices by $2000.
Maybe you could pit the far dealer price against the local dealer and get them to lower the price.
By the way--- when our new trailer arrived at the dealer we picked it up and drove to a nearby full hook up campground to stay for a weekend and try everything out plus load it with our stuff. It was a great weekend in the new RV.
