I have a 2001 Chevy K2500HD with the 6.0 litre, 4-sp auto, and 4:10 gears.
The tires are a bit larger than stock, but no lift kit- 285/75/16.
Highway cruising while empty gets about 14 mpg, prolly 12 around town. Loading it up pretty heavy doesn't affect milage as much as one would think.
The only time I would rather have 3:73 is during my semi-regular run down to the Portland area, when I don't need to carry much, and I-5 is pretty flat along that route. Whenever I have a load, or am towing, I'm glad I have the 4:10 axles.
The race car set-up is pretty light, as I have a 1500lb flatbed trailer, and my car is an ITS class 944.
