Sorry for the delay in reply guy's, haven't checked this thread till now. Anyhow, I see 2000rpm at 75mph, 1900 at 70mph, 1800 at 65mph. My mileage around town driving with winter fuel and winter conditions it can drop as low as 13.5mpg and go as high as 17 on the highway. With summer fuel and warmer conditions everything goes up, around town 15-16 and highway 18 and even 20 on rare ocassion. Around these parts it's hard to get the trucks T-stat to open in winter, my usual coolant temps are around 166F and ocassionally 174F if we tow, that effects mileage the most, not being able to get up to operating temps. I have thought about getting a winter front for the trucks grill, or at least a piece of cardboard stuck in there.
