Previous Ram was a 5.9 48re with a 3:73. New truck 2012 6.7 68re with max tow ie. 4:10. I have pulled the same fiver over the same hills. Now this may only apply to the Ram which is the truck you are asking about. The 4:10 makes a very positive difference when pulling the hills/mountains etc. On the flats either will work. Put on the tow/haul mode, engage exhaust brake set the cruise and truck on down the road. Mine is a daily driver and no regrets about fuel useage.
