Oh no, I made a point to miss the 6.0L debacle. I was the first (I think) to get a 6.4L though. I hope the surprise that I read into your post, Duane, was that of trading a 2008 model truck for an '09, and not that you have second thoughts about your recommendations. I normally would not have traded this quickly, but actually I had my 6.4L for 2.25 years (I usually keep 3-4 years, unless I really like a vehicle, or unless someone offers me a king's ransom for it). I really like my wife's Acura and we have kept it about 5 years, and likely will run it another 1-2, so I really do not trade THAT often. So far, I have really liked my GMC. It has been a good choice seemingly for me and my current needs, which seem to be ever-changing. I have not put enough miles obviously on it yet to tell about its durability and longevity, but I have put enough on it to have some impression of its features and performance. I will also say that my dealer service person said one of his reps told him there had been some running programmer changes to eak out a few more ponies and some more pound feet of torque. I cannot attest to the validity of this, but I can say my truck feels quite a bit stronger than my friend's 2007.5 model (he is not happy about this finding), even though they share the same rear axle ratios and running hardware; his truck has but 21,000 miles on it. I am also getting better mileage than I expected with DPF in place. So far, so good.
