The 6.0 had tons of problems, common knowledge. The 6.4 (which I have) has had very few catastrophic failures, so if your bar is so low that the lack of widespread catastrophic failures is a testament to success, then yeah, it has been great.
The fuel economy is piss poor pitiful. The power (while adequate and I am not complaining) is NOT on par with the Dmax.
Let's not compare performance with mods -- amongst those who do such things it has been known for some time that the Dmax is very mod friendly, with tons of power to be added fairly cheaply.
The Dmax, especially when combined with the Alli, is a better powertrain combo.
Even knowing this I chose a 2008 King Ranch. If it were not for the consistent 9-12mpg, mixed, that I get (when my 05 Dodge consistently got 18-20 doing the same driving), I would love my truck. As it is, I recognize its flaws.
