I bought my 2006 new and have had it 9 years. Other than a bad wiring harness and a few sensor codes I have had no problems with it. I too have heard all the blah about the 6.0. The only definite is to do the EGR delete. I have 92,000 miles on mine and just did a week long trip to the mountains and she did great! My mechanic has said most of the problems occur with people toying them up improperly. My only problem is I don't drive her enough since my work vehicle is in the yard!
