With a GVW of 22,170 I got 14 mpg.
Love the power of this Duramax, and still able to pass people.
No temp issues. The tow/haul feature performed flawlessly.
I still can't stop grining
Especially with a 6yd dump trailer loaded with about 7yd of wet pit run gravel. Yes, I got the scale tickets and the guy at the scale was shocked.
Especially after my 8th trip.
