New 2012 HO 800

[RonD]

Hard to believe the HO and 4 wheel drive extract that much of a mileage penalty. My pore ole 350/650 4x2 in my signature gets 16-17 on the highway unloaded and 10. 2 pulling our 16K GVWR 5th wheel (13"2" tall, 102" wide) at 65 MPH on the interstate. That's about the same as my 2002 3500 4x2 HO/6-speed with 4. 10s, DD2 injectors and Edge EZ (347/762 @ rear wheels).

My 2012 H. O. is the same truck as Rusty has, I get the very same mileage, 10. 2 towing, 16-17 empty on the road, my 5th wheel is a little lighter, and I tow at 60-62 most of the time, but were close, I have 5000 miles so far, it should improve a little with more miles added.
