Ram HD 1000 lb-ft MPG loop
Towing 29k. Nice to see they have a gauge that tells you how "full" the DPF is now. That's handy.... VIDEO Almost 9mpg pulling 29k, which means about 37,000 GCW. Pretty incredible. Interesti...

Cummins doesn't configure these engines according to some hypothetical make believe situation where everything is "constant". They configure these engines and change their power output for real world applications and uses for these engines. Again, we are debating why Cummins has different power levels for medium duty trucks, not some made up unicorn make believe scenario that doesn't apply to any medium duty truck in the real world that Cummins would never tune these engines for.
An RV, fire apparatus, box van, small city bus (where ISBs are used), are all "MD" trucks. Yet I clearly showed the hp rating goes up when the expected service life goes down (Fire/RV), and vice versa (city bus running day in day out).
Your original statement was once emissions certified, an engine's hp level has no correlation to expected service life. The power ratings I linked showed otherwise, despite identical emissions certification.
Cummins does not make a 200hp expecting you to "floor it all the time", then make a 300hp expecting you to 66% throttle it, then make a 400hp expecting you to use half the power.
