If the same situation would have happened towing something along the lines of a Billfisher....
It would be a very stressful situation that's for sure!!!
They ran diagnostics (I don't know what that really means) and the service guy said that everything except the injector was fine so he really couldn't explain the complete shut down.
I guess I will just have to consider that a mystery hopefully never to be revisited. This event made me realize that I need to learn something about my diesel motor. Thanks again to you guys!
Now to find an Outerbanks to tow with the truck.....
