Raw Fuel Odor.

From time to time while driving long distances on the highway I smell diesel. Sometimes it gets so bad that I have to crack the windows and let it flush out. Does this sound normal?

Normal, no. But others have experienced a similar problem. They were getting exhaust smell in the cab. Ended up usually being a leaking exhaust gasket on the back of the EGR cooler.
