I finally got to take my NT 21FBS for a decent highway trip and I have to say I am very happy with the 6.4. I know most people like the diesel. I understand as I used to own one. but if you can't afford the $8K markup for the oil burner, the 6.4L Hemi makes a great tow vehicle.
Before this trip I kept thinking I wanted to change the gears from 3.73 to 4.10. Now I don't believe it is needed for the weight I tow. The truck did not seem to care. It easily maintained highway speed even on grades. Overall very happy with it.
