When buying a new TT how do you negotiate

I do the same thing that I do when buying a car. I check around the country on the internet and ask for a price that includes all the options I want. I recently bought a Flagstaff Micro lite from a dealer in California and I live in Sedona, AZ I negotiated the price over the phone and then drove to CA to pickup. IN 2018 I bought a new f150 the same way and went to Peoria IL to pick it up. It saved me about 4K over AZ, CA, TX, OK negotiated prices. The dealer that wants to sell will make the price interesting. IN 2004 I bought a 40' DP in Maine and drove it home to Colorado.
