I have a 2011 GMC Sierra 2500HD 4wd 6.0/6 sp/3.73 and wish I had gotten the 4.10 for several reasons.
1) better pulling power
2) better mpg
3) and the biggest reason, enough rpms at normal towing speeds to stay in lower gear. with my 3.73, the rpms are too low to handle much hill or wind without shifting down. A few hundred more rpms would help.
Folks have to realize that in the old days, top gear in the transmission resulted in much higher rpms at highway speeds, but now with double over drive on these 6 speeds, you have plenty of gears to run 70 plus at decent rpms.
