Just thought I would post a good thing about the 6.0l. I bought my 05 with just over 200k on it and I have not been happier. Sure, I had to fix the FICM, but that cost me 1hr (I suck at soldering) and I had to check alot of stuff over before I bought it, but it was worth it.
I do plan on bullet proofing it eventually, but for now I am just going to keep an eye on things, and drive it.
Just thought with all the bad things and horror stories on here, I thought I would post a good experience.
