I was reading a post on this board and I read something that contradicted what I understood my warranty coverage to be. The way I read it from the dealer lot you get 3yr/36K bumper to bumper, 5yr/60K powertrain, and if you have a diesel 5yr/100K on the engine only. In other words if you put in excess of 60K on your truck within the initial 5 years of ownership the diesel engine is still covered. I read my warranty book again and that is still the way that I understand it.... I may however be reading this incorrectly.
