I would also "second" the 4:10 gears.
I've got 2014 Ram 3500 dually/Cummins/Aisin w/3:73 gears.
From talking on here, appears the shift points (in Tow/Haul mode) for sixth gear are at different speeds, depending on rear axle ratio.
3:42's shift at about 65 MPH
3:73's shift at about 58 MPH
4:10's shift at about 54 MPH.
Or really close to those speeds for each vehicle.
I find mine will sometimes gear hunt when running in the low 60-62 MPH speed range, as it seems it is just not far enough into sixth gear to hold it there. So back and forth between 5th and 6th it goes, until I get tired of it and lock 6th gear out.
I do prefer to drive somewhat slowly, and the 62-64 MPH speed range is favorite to me. I am thinking that perhaps the 4:10's would have been better for that speed range, and others here with that axle ratio have been getting similar fuel mileage compared to what I get with the 3:73"s.
So something worth considering.
