“Consider also that the 5.9 (and now 6.7) Cummins B motor is used extensively in pickup and medium duty trucks. A pickup driving at 70mph on a highway trip unladen typically gets 20mpg (3.5gph) and runs around 1500rpm. That's about 65hp. These engines are rated at around 300hp-350hp so highway cruising is nowhere near 80%. Even lower load putt-putting around town. Known to run easily to 500k miles, which at an average speed of 40mph, that's 12,500hrs.”

Huge difference Ski. Those truck engines accelerate, decelerate and most importantly climb HILLS.
