More like 17 tops is what i would believe there.

Oh,I don't believe it,either,but you better get all the fact straight before doubting someone. The fact is,he has a 6.2 diesel...check his signature.
I know one thing,I get my best mileage at 65 mph...2-3 MPG better. Once I get up to 70-75 it drops off and that's with taller tires spinning lower RPMs and on the hiway that's an advantage. I'm at about 1800 RPM and that's the sweet spot.
