I have the tendency to use tow/haul most of the time. Can't tell you why. Just a little better engine braking I guess. It doesn't seem to affect mileage as I would think it would. We run best at about 1900 RPM which is about 67 MPH. I let it do its own shifting on hills but pull it down a gear or two out of overdrive on the downside. Being diesel it will drive a little different than the big V10s
