What kind of hwy mileage are people getting?

Last week, I got my best to date, and part of it was in some heavy traffic. I got 627 miles with an average of 18.5 from what the computer said. Most of my freeway miles I had the cruise control set at 75. I did put in slightly over 35 gallons when I filled up My truck has about 4500 miles on it now. I love this thing.
