I would think most Cummins and Duramax equipped trucks would be capable of running up and down the highway for 500k miles in 2 - 3 years. What about the new Fords? I find the trucks that make the million mile mark over a 15 year period more impressive.
The Duramax has the shortest design life, which was reduced to a B10 of 215,000 with the last revision. Powerstroke also went down to 225k with the 6.7L (it was 250k with the 6.0/6.4 but B10 clearly did not meet the actual experience which is called "L10"). The "10" stands for a 10% catastrophic engine failure. B=design, L=actual.
The Cummins 6.7L B10 is 385,000. Note those are all rating for cab-chassis configurations. Pickups ratings may be lower. The B10 ratings are published annually in "Fleet Owner" magazine.
I'm pretty sure the B10 ratings are why Ford doesn't put their diesel in the MDTs. It's probably also why you can't order the higher HP levels in the Cummins unless its for RV or Emergency vehicle use.
