That's why I initially bought my beast. No emissions on the 5.9, so I can get 22mpg city, but drops significantly on highway due to 4.10 gears. I would take off emissions stuff if I bought a new diesel. I have read that the EGR kills the long term reliability due to soot build up.
Looks like the titan or ecodiesel from ram are managing 18-25 without modification.
