i suppose it would entirely depend on how long you keep a vehicle. The factory warranty the truck comes with is pretty darn good. 5 yr 100k on the truck and 5 yr or 160k on the cummins. For us, even with this 22 on the way i only forsee keeping it for 3 ish years, will definatly be gone before 100k on the clock to get best value. If i was anticipating keeping a truck longer term, id re-consider extra warranty after the factory warranty ran out. Who knows if youll want to get rid of it in that time frame, and while some may see the extended warranty as a selling feature, it generally doesn't amount to much when you go to sell a vehicle privately, or especially a trade in, dealers love getting vehicles in with extended warranties, but they sure wont compensate YOU for it.
