I just finished a 3300 mile round trip from Southern Calif to Eastern Idaho. I've made this trip in the past with my 2001 DRW CTD with the NV5600. This 09 with the 6 speed auto is a pleasure to drive. Most of the time I would just let the trans do it's thing. Trans temp never got over about 160 on any of the hills. I drove at about 65mph( about 1750 RPM ) and my calculated MPG was in the 9-10 range.
The MaxBrake is the only way to go if you want smooth brakeing. And the factory exhaust brake works as advertised. My old 01 was a good running truck but this 09 is the best.
