I have the 3.21s with 315/70/17 MTs. They're not "too" bad.
I do notice a lack of passing power on the highway, but I can still go 70+ in 6th. If I need to pass 5th works just fine.
As for mileage, i'm getting 15-17 city, 20-22 highway (yes i corrected the speedo/mpg ad have confirmed with miles/tank/fill-up)
I have a set of factory 4.10s I'm going to install, they'll keep me mileage happy and get back some of the power I lost.
Keep in mind, this is lifted, locked and MTed.
It was great when it was stock, 6th was plenty and 24mpg.
