Go over to the dieselstop.com website, click on the forums, click on 6.0 and see how well they have the problems worked out!
Some folks never learn! I was also leaning toward a new Ford 7 months ago, based on good performance from my dad's 2002 7.3. A little reading took care of that! I bought the 2003 Dodge/Cummins and have been very happy 12,000 trouble free miles later. There is not that much difference in the trucks anymore. There is a HUGE difference in the powertrain. Please go check it out for yourself, also see how well Ford is backing them. Just my .02. By the way the one thing I HATE about my dad's Ford is the ridiculous turning radius. The Quad Cab works out great for me, to each his own.
