I should have paid more attention to this site before I actually picked up my truck.
Just purchased my 2020 Longhorn a month ago. Bought an extended warranty from the dealer.
I only put about 7k miles per year on my truck, so bought a 7 year/60k mile "bumper to bumper" warranty for $1800. (talked him down $700 from his first quote.) However, now that I actually pay better attention, I realize it is a 3rd party warranty and not mopar. And, the "payinfull" code still works on the ziegler site - so I can get the same coverage, with a true Mopar warranty - for $900!
Looks like I will need to be calling the dealer and cancel that warranty.
