Hiya mndemohead!
Don't be put off by a small, high profile, vocal minority. Yes the 6.0 has had some growing pains but I guarantee that there is one heck of a lot of happy 6.0 owners out there. People love to squawk. Relax, work out the minor glitches in your truck and thank God every time you start up that you didn't buy a Chevy Duramax!!
