My dad has a 2001 1/2 ton extended cab with the gasser and a long bed. That thing gets awsome mileage. I used it a few times. I'd fill the tank with plus and it would get right at 24mpg in the cascades going from Salem to Bend. A few good hills to climb.
If I didn't pull the heavier loads then I would have looked for something closer to that.
