You can't really beat a mild 350 with overdrive for mileage in one of these trucks. My 350 with Vortec heads, a 700R4, and 3.73's gets 14mpg, and that's with me cruising fast and 28" tires. If you got a nice mild 350, with either a 700R4 or a 5-speed, and a rear in the 3.42 / 3.73 range, you could probably do that pretty easily as well.
