F350 Super Duty vs 3500 Denali vs The Ike Pulling 30k lbs

After watching the video I'm a surprised that the GM didn't stick closer to the Ford's time because the GM ran between 25 and 28 hundred rpm all the way up where as the Ford was running in the 21 to 25 hundred rpm range. When the Ford would loose a gear the engine would rev to 2500 rpm which should have given enough of a power boost to allow the truck to accelerate a bit, yet it never did. With the Powerstroke running as low in its rpm range as it did, it maybe left room on the table for the Cummins to compete. I think the Chevy under performed.
