As you know the Cummings is a beast ad has a towing capacity of 16,500 lb the highly sought after manual transmission gives you total control . Truck consistently gets 21 mpg except when towing. I just towed an 11,000 lb trailer and old car to upstate NY and could not only maintain speed limit but could accelerate and pass others. I am second owner, purchased in Aug , 2004. Truck has been well maintained . I have replaced many parts over the years keeping the truck in top notch condition. Comes with extra tires and amounted set of 4 snow tires. Having maintained this truck myself I have acquired many spare and new parts over the years, they ar3 all included.
