It's been a great truck. There are times where I wish I had the 4.7 instead of the 5.9, but other than that, I can't complain. The only major problem I've had with it was the transmission went out at around 60K. I took it to Powertrain Development and they told me it was most likely not assembled correctly at the factory because of the way it failed.
Don't know that there is any one favorite. It's the whole package. Maybe the 4x4 shift lever since this is the only year the QuadCab had it.
