3/4 ton gasser gas mileage?
Monday we are going to try out a 3/4 ton gas Silverado 3/4 ton, 4.1 axle ratio, 4WD. Going from a Tundra because we've run out of GVWR on the truck (because we take too much stuff). We get 8-9 MP...

I was concerned about gas mileage because the 3/4 ton itself weighs 1200 lbs more than the tundra, has less HP (360 vs my 381), and has a taller gear ratio (4.1 vs 4.3 in the Tundra). All of those numbers are going in the wrong direction for power and gas mileage.
Don't be concerned with the rear axle ratio too much. It's been a while since I looked up the ratios, but IIRC the Tundra has unusually tall (numerically low) transmission ratios which necessitates a lower (numerically high) rear axle ratio. Overall gearing should be comparable, as should performance and mileage, although you might be a little slower.
