What is the average mpg you guy's get on a 6.0L? What modifications have gained you better mileage? I probably am wasting my time with my truck considering it has a Harbor Truck Body Workmaster box on it. Not the most aerodynamic.

worst i've gotten was 12 pulling a 5,500 pound trailer across the US at 70mph the best was empty 40-45 mph and got 22 mpg

Welcome Radar!
I get around 18 in my '05 with the Predator in 65hp mode.........USUALLY because I sometimes have a hard time keeping my foot out of her.

My work truck only gets 10 mpg. It weighs approx 11,000lbs. Looking to do something to increase the mpg. Diesel is aroung $3.29/gal.

You could try a tuner I guess - most seem to boast they'll give ya about a 2MPG increase in the economy tune. If we don't have one already I think I'll start a thread in General Discussion on everyone's tips and tricks to better fuel economy.
