You have it correct, the higher number is better for towing and the lower number is for better fuel mileage.
Surely you meant numerically lower...or higher gears.As a rule of thumb numerically higher gears will provide better fuel economy...
Surely you meant "a low gear ratio", right?Sometimes modern trucks will skimp on the size of the diff carrier to keep costs down and mileage up, at the cost of reliability. With a small carrier and a high gear ratio (4:11 eg), the pinion diameter gets quite small and the contact patch is also small. You need a bigger carrier so your ring gear can be bigger and also your pinion diameter. But, they cost more and take more HP to turn those bigger bearings etc.
