Re-gear to 3.73 or 4.10 and get a tune. $500 gears, $300 tune and you're not only increasing your capacity but driveability. You can also go to 3.90 but it's not a GM ratio, rather aftermarket. The only difference between your 5400lbs capacity and the next higher given all the other variables are the same is gearing.
