Usually around 70, which is hard for me because my last pickup liked 62, and got the best mileage there. If I try that with this one, the transmission is constantly shifting. If I drive 70, that gets me 2000 rpm, and it doesn't shift nearly as much as driving slower.
One time driving across the state, there was almost no wind. I told the DW that I was going to do a mileage test and didn't use the cruise control, which I usually do. I stuck it at 55 and held my foot steady, and let the speed drop uphill and raise on downhills. When we got to our destination 335 miles later, we got 9 mpg.
Next time I tried with similar circumstances on the same route, I put the cruise at 69 and we got 9 mpg. That does not compute in my mind, but I have repeated the test, and it is correct for my rig. If we have a side wind, I can be as low as 7 mpg only going 55. And unfortunately, this is repeatable. It hurts only getting 200 miles out of a tank on a bad day.
When we retire, I won't have to drive on the really windy days.
