There is a post on Cumminsforum.com about a 2011 Ram that has racked up 1/2 million miles in less than 3 years. THAT is a lot of time behind the wheel.
I would think most Cummins and Duramax equipped trucks would be capable of running up and down the highway for 500k miles in 2 - 3 years. What about the new Fords? I find the trucks that make the million mile mark over a 15 year period more impressive.
