I get the idea they are going to test all three trucks again. Both the Ford and GM should have just enough power to tow 23000 lbs up the hill at the 60 mph speed limit. With 3.73 gears the Ford would be running about 2600 rpm in 4th gear at 60 mph. The Chevy would only be turning about 2275 so maybe the Ford will have the advantage. If it ends up that both trucks drop to third gear the advantage will be in GM's favor.....
If the Ford can't manage 60 mph it might have to drop to third and rev to 3000 rpm where it's only able to do about 52 mph. If the Chevy drops to 3rd and revs to 3000 rpm it will be making 57 mph.
I'm going to guess 8 minutes 40 seconds for the winner.

2017 Ford F-350 diesel dually doesn't come with a 3.73 gear.

Nice. I like the idea of a 3.55 in the new dually. I don't actually know how but I totally screwed those numbers up. The Powerstroke with 3.55 gears will turn 2616 rpm in 4th gear at 60 mph and the Duramax shouldl be running 2365 rpm in 4th gear at 60 mph. So the Ford might make a little more HP at the speed limit. If the trucks drop down to 3rd gear and rev toward the red line the Duramax will travel about 56 mph @ 3100 rpm and the Ford at 3100 rpm would be going about 54 mph. (assuming they can rev to 3100 rpm... I don't know how fast the power drops off over 2800 rpm.) It really should be close.
