    2015 2500 St Tradesman 4x4 Quad Cab, Camper shell, 6 speed manual G56 stick, K&N air filter. Bought used Omaha, drove to Los Angeles 24.1 mpg. Up & down California 6 times in 5 weeks. 10,000 miles (27k to 37k). 8800lbs stock chrome 18" steel rims, 275-70-18 Firestone tires. Avg city 17-21mpg. Freeway 22-28mpg. Is something wrong? I been driving stick since 1970s.
    Drove 2hrs + 6hrs + 2hts off road in 1st & 2nd 4H in California’s Kern mountains 3000-8500 ft. Elevation & got 15-16mpg? Something was wrong per my landlord neighbors! Great ride in Air Con shopping land & mountain cabins. Changed all filters and all fluids except power steering and radiator and Brake fluids and clutch fluid. Kern County, Bakersfield Dealer said 1% of all trucks get a G56 6 speed manual. He said this trans is the same as the Dodge Viper! Fleet mgr said that the 24mpg is normal & that the automatic transmission sucks 5mpg to run correctly.

    viper has a Tremec TR-6060 (newer version of T56), not a G56. So that guy is a ding bat.

    They are basically polar opposites.

    I have a G56 and 3:42 ( highway gears ).15-16 is average around town. 16-20 highway, hand calculated actual mileage. No way you are getting over 24 on a stock truck... If you are I wouldn't change a thing. And like SilverSurfer15 stated Viper runs a very different trans. Yours is much heavier duty and built totally different.
