Brian Parker just bought a 199,000 mile 6.7 says I drives like a brand new truck. Its a dually and from the sounds of it its been hooked to a trailer a good amount of its life. I'll be interested to see how it works out for him.
As soon as I see him again I'll get a picture
Standard work year is 2080 hours and its not uncommon for guys to drive 10 - 14 hours a day as an owner operator.
Especially if you get paid by the mile.
For a 6.7 to have that many miles you would have to average about 66 mph and be in the truck 8 hours a day for the last there years. I just based that basically on a standard work year for hours. 2000 hours a year.
I find that story to be a lite far fetched but I guess its possible if he bought a 2011 in early 2010
