3.21 Vs. 3.92 gear, worth the money?

17 limited 3.92 great
19 limited 3.21 hate
21 limited 3.92 great sound, I see zero benefit to 3.21, unless you never tow, stay on interstate, or are bothered by a great sounding engine. however on interstate I did get 22mpg with 3.21. I can get over 20 mpg on 3.92 if I try but letting it rev is just too much fun, plus much better for the engine, ok, imo.

I’ve pretty much come to the conclusion the Hemi’s with the higher gears are for those who care an awful lot about fuel mileage and didn’t really buy a truck to be a truck and the Hemi’s that come with the lower gears are for those who just simply know they bought a truck and didn’t buy something with gas mileage in mind and want their truck’s full potential.
