If you want a 2500+ chassis, you wil probably end up with a 4.10 gear.
I guess you would have to ask yourself why do you want that heavy a chassis. Most of the time is is for payload/towing capacity, then the 4.10 helps a great deal.

On that truck, the difference in MPG between the 4.10 and 3.73 won't be that much.
