I took the truck in for service just before it was out of warranty. It has 100,300 but was taken in to log the mileage before I went over. It felt down on power and had a few days that it started hard.....this is what is being covered under warranty
EGR Cooler (coolant flush obviously)
Oil Cooler (oil change obviously)
Rear Main Seal
Glad I took it in as I was not going to. When I get it back I will be able to mod it the way I want to. BTW this truck has hauled a 17,000lb trailer at least once a month for the past 30,000 miles with no issues.
