on this truck(3.92) having regretted not getting the 4.10(I think that was the tall gear option) on my '08 2500 Cummins. I got the 3.73 on that truck thinking it would have plenty of torque to do whatever I threw at it and the 3.73s are just long enough to have it guessing gears a lot at ~65mph with some 35" tires on it. Towed ok but had to go back to a 33" to keep it from hunting all the time.
