I did opt out, went with Stern Law. The main reason I did is because I already purchased the extended factory warranty 8/100,000 ($3,600) so the extended warranty FCA is offering does me no good. I have 36K on my 2016. I also feel because of this my truck has devaluated more than the $3,075 FCA if offering let alone what I paid for the extended warranty. I have to admit I do love the truck, however I wish it had the Cummins. Might have to upgrade, have had many Cummins before and they are outstanding!
