That is pretty good mpg. I know regen burns a lot of fuel with those trucks.

I towed a waggy through Ohio and got 10.3 mpg with cruise set at 65 mph in tow/haul mode with gentle acceleration. With a Fiero on the trailer coming back the same roads at the same speeds, I got 15.4 mpg.

The 6.4 isn't bad, but if I were ever to buy a new truck I would probably wait for the 4.4-liter diesel to see what kind of mpgs it pulls. My understanding of the new diesel is it will be tuned for mpg, not big power like the 6.4. I don't need a lot of power, my IDI is actually fine, I would like a new truck with IDI-like mileage. I'm afraid that's not possible with the new emissions regs. Not to mention how much all those emissions regs cost.
