I bit the bullet and ordered one today. Laramie megacab shortbox dually with the 6.7, AISIN, 3.73’s, airbags and more. The wait is gonna suck though.
I highly advise changing to 3.42's if combined will be 29K or less. If over that get the 4.10's.
The lower starting gears of the AISIN make the 3.42's work VERY well. Towing in 5th at 60 at 1,750rpm is perfect. Now unhitch and the 6th gear makes for great solo mileage. 4.10's in 6th have the same 1,750rpm's at 60.
Look at the chart! Compare the bottom three lines.
