P.S. I knew what he meant to say about the 02' but he didn't say it, and it was 03' that offered both 7.3 and 6.0 as others have said.
I get over 20mpg with my F-250 6.0 (stock motor) crew cab 4x4 as long as I keep it under 70 on the highway, and I'm running 38's and 3.73 gears. I can't immagine it would be any different in an excursion as long as the driver has a light foot and keeps the speeds below 70.
