Based on the way the Duramax wasted the Powestroke last time I'm not sure 40 more ponies at 2900 rpm is going to be enough to give the Ford a victory if the trailer weight and hill are the same this time. A hill and trailer weight combination can be chosen that will expose a weak shift point in a truck. An eight speed transmission would make it tougher and an infinely variable would be the ultimate. I wonder how long till we'll see diesel electric trucks recharging their batteries on the down grades so they can be drained again on the big climb.
I'll go Ford first Chevy second and Ram third.
