I wound up buying an '06 for that reason, I did not want the next generation engine with the loss in fuel efficiency. Could have made a couple of excellent deals if I had been willing to accept the 6.7 for my limited trailer hauling.
Have had my 5.9 up to 25.2 MPG on a 600 mile trip with much construction and traffic delays that took 4 hours to do a 2 hour drive, and lost over a 1/2 hour in construction, for a 2.5 hour stop and go fuel eater!
