The perfect gear ratio for stock sized tires (235/75 R15's) is 3.42, good fuel economy.

For pulling 5k regularly, I'd suggest 3.73 gears, which will still grant decent fuel economy running empty.

2.73's really won't allow you to pull a stump out of the ground, or 5k at highway speeds with a tail wind

GM geared a LOT of these 6.2's will TALL gears, mainly cause the target was maximum fuel economy, later on, they wouldn't pull well and the owner usually suspected the poor diesel engine under the hood. It's the gears.
