I have been getting around 15 to 16 intown on my daily commute, but lately all I seem to get is 13 to 14 same as Mike. The towing mileage has been down as well. Last weekends haul is a trip we make about every other month and we were down 2 MPG, normally on the 300 mile round trip we would get 12 to 13, last weekend we got 10.
But on the lighter side the V10 Gasser we would have had to put fuel in it to even think about coming home, this one does it easily on 1 tank full. Dang I love this truck.
