Any reason why? We've had power strokes around here for a while (a live in a rural town...everyone has a diesel....but mainly farmers) and we haven't had any problems.
Also, I don't think there are many stock parts left in that engine
i was kinda curious about that too. i don't thinnk ford built a 6.0 deisel. it was a 6.9, and dependable. a torque monster.
the 7.3L powerstroke turbodeisel, has no mechanical problems, although they tend to have some electronics problems here and there.
i've been towing on and off for about 15 years. the guy i tow for has fords, and they have powerstrokes in em....never had a problem.
