If you haven't already, I suggest printing out the PDI list and taking it with you when you pick up your new trailer and check off each item. And, insist on dealer doing a walkthrough. The last dealer I dealt with, Robbins RV in Idabell, OK, wouldn't do squat in the way of a walkthrough. He pretty much just gave us the keys and then disappeared into the shop.
The crazy thing was that there were upgrades I wanted to do when buying the unit and he had zero interest in upselling us anything. The only upselling they seemed interested in doing (which we didn't do) was the dealer's wife tried to sell us an extended warranty.
