If I were to buy a 2013 3500 Ram with the 6.7 and Aisin 6 speed it would be the 3:42. The 6.7 has more than enough low rpm torque to handle the 3:42 and you will enjoy the truck at light loads on the freeway with the 3:42. I am sure in the upcoming hill climb tests Ram will supply the 3:42 rear end and should be able to keep up with the Ford and Chevy with that combination. If they supply the 4:10 then I predict they will get their b&*ts kicked again.
The 2013 isnt available yet in the 2500-3500.
You will also get more emissions in the 2013 trucks.
