What I have never seen is to like sized engines, same load, same gears, same grade, compare the whoa.

The guys on TFL Truck on youtube have run many tests of comparably equipped trucks and how they perform towing the same load up and DOWN the Eisenhower Pass in Colorado. Going up, they measure the time. Coming DOWN (assuming that's what you are referring to by "whoa"), they measure the number of times they have to touch the brakes to maintain the set speed of descent.

We had a 2001 8.1 gas engine and 3500 2wd dually. We have a 2005 3500 2wd duramax and have driven on I-84 many time with both trucks. Going down the cabbage hill for 6 miles in Oregon there was no difference in being under control towing the same fifth. chevman

Does your 2005 Duramax have an aftermarket exhaust brake.
Exhaust brakes are now standard equipment and make a big difference


No it just has the allison holding back going down a grade. Has worked great on any mountain we have towed on. Heavier fifth wheels should have a truck with the exhaust brake. chevman

TFL Truck did the IKE pulling a 10k lb trailer in the 7.3, while they did it in roughly the same time going up the grade pulling a 30k lbs trailer in a F350 DRW with the 6.7 diesel. That's a HUGE difference in power considering the diesel was pulling an extra 20k lbs. Furthermore the mpg were roughly the same. Finally another noticeable difference was the diesel was far quieter going up the grade without the constant loud droning of the big block gasser. Going down the hill was also much easier with the advantage of the diesel having the exhaust brake.

At the end of the day, the decision seems to come down to whether it's worth it to you to spend roughly $8500 less for the gasser but suffer with more noise and a towing experience that's not as relaxing as the diesel.
