Another thing to look at to get the true numbers is if you ask they are suposed to show you the full invoice not just the first page but also the secound page... and at the bottom of the secound page you will see a line that says something like a/z or a/z plan then a number that is the a/z plan price then D and that is the d-plan price and then the X or x-plan and a price if your ordering look at a full invoice for a truck close to what your ordering.
My dealer freely showed all this to me without asking, but i know i have the oddball dealer, that also just sells at invoice no haggling. also if you ordered out and are doing x-plan all the AXZD plans will print out on the 'order confirmation' (not the DORA) atleast they did on mine.
