I have had 4.10 gears on all my trucks until the current one which is a diesel with 3.73 gears. I had the same or better gas mileage as anyone using taller gears and that was with 4-speed transmissions. Current pickups have 6-speed transmissions and 5th and 6th are overdrive gears.
I would want the 4.10 to have the best possible acceleration when merging with traffic on a freeway and for passing slow moving semi's on steep grades. The 4.10 gears put the engine more readily into the peak torque area of 4200 RPM.
With a very heavy 8,000 lb. truck hauling a 4,000 lb. payload fuel economy is not worth talking about. It is what it is and the gears are not going to make a difference in the real world. The taller gears help with the EPA CAFE figures for the truck manufactures but that is about it.
