I traveled from the Texas City / La Marque area to Austin Texas for a few days and drove around Austin while I was there and traveled back yesterday on the same tank of gas and averaged 23.6 mpg average of city/hwy driving and had construction detours as well as some 75 mph speed zones. This also includes the whole back cab area filled with luggage and the wife's shopping items. See the picture below of the gas mileage.
