I have owned many as well. Just sold my 7.3 crew cab 4x4 short bed.. Been a mechanic most of my adult life. I respect your opinion, but in my first hand experience I think they are all crap now. None of them will ever live up to the longevity of the 7.3 PSD or the 5.9 12 valve without putting a lot of money into repairs.
Now that part is true. Just as anything else, the more parts and systems, the more there is to go wrong at some point.
