24.7 is impressive. I wouldn't have expected that high.

I have driven that route many times. I will make the same comment that I did when they tested the EB. 65 MPH on that stretch is SLOW. Would like to see what the difference is at 75.

I would like them to stretch these tests out to 100-150 miles or so. That's why the computer is off a little. Also my truck at 75 does as good if not a little better @ 75 if traffic will allow as apposed to 65. With the 3.42 gears @ 65 the motor is well below the torque band. 75 is the sweet spot for mine. I've seen 27 at that speed on the lie-o-meter for a couple hundred mile trip.

I had 3:42's in my last Dually and there is no way I would get better mileage at 75 then 65! Not calling you a liar but NO WAY!
