If your dealer didn't keep last year's model on lot long that may help you. I ordered from a small dealer, they never had any new ones on the lot. I think that helped me get scheduled for mid January. Maybe BS but just my guess.
I work at a used car dealer and there a lot of trucks, domestic and foreign that have no provision for a ball or hitch. Ask U-Haul they love to sell them. PS a lot of SUV's have recievers.
