This is killing me. It killed me 6 months ago when I first tried (and 2017s were maybe not quite hitting dealerships and the new 3.5 Eco was further from the dealerships). I can't find a way, during the process to add the Max Tow package. I am specifically looking at a Lariat Screw 3.5 Eco, but I tried all kinds of bed size, trim level, and cab options, but all I get is the basic tow package. Before, I just thought it was that the 2017 was so new, or that 3.5 Ecos weren't even close, but still?
Thanks,

Scroll down and pick the 3.55 rear end first and then scroll back up and the max tow package will appear.

 

Likewise, to make HDP appear, pick 3.73 rear end. (has to also have 6.5' bed)
