Obviously there are some smarter people than me posting to this thread with good and valuable info.

My $0.02, although apples and oranges.
'98 Chev crew 4x4 short bed, Vortec 5.7, auto, 285/75-16 AT tires. Best I ever did was just over 15mpg, but never did anything extreme to get better mileage, just tried to not do anything too stupid while paying attention on a road trip or two.
'00 Chev crew 4x4 short bed ('88-98 body style), Vortec 7.4, auto, 285/75-16 AT tires. Best I ever did was around 13.5mpg, but never did anything extreme to get better mileage, just tried to not do anything too stupid while paying attention on a road trip or two.

Yes the 5.7 did marginaly better MPG wise, but the 7.4 was just better to drive.
YMMV... literally!
