Here's a daily driver that averages 2,500 miles a month towing a Mirage gooseneck toy hauler trailer around the Intermountain West. This 2014 Ram 3500 has the H.O. 6.7L Cummins and Aisin 6-speed automatic transmission. We've since added a billet leveling kit from jackit.com, Bilstien shocks front and rear, AMP Research PowerSteps, Retrax Pro MX bed cover, BedTread bed liner, Fuel Hostage wheels and 35x10.50R20 Toyo Open Country R/T tires. We've also added a Bully Dog GT tuner with ECM unlock. Nothing to brag about on fuel economy, with 16mpg empty on the highway and 8 to 10mpg with the trailer.
