I've driven around a lot with my scanner attached to the truck and on the data stream you can watch the engine load on most vehicles. A hard headwind does make the load a lot worse. It goes up almost exponentially at any speed over 55. I think I'm running abut 1800 at 55 with my power stroke. The truck weighs about 3 tons so around here that's enough. Those low gears I have just run the RPM up way too much.
I feel sorry for the guy that bought my last truck. I do miss it but the gas mileage sucked. I had big mud tires on it and a C-6 transmission. NO overdrive.
It got 8 MPG no matter what it was doing.
