Well, I've got about 700 miles on it, and over all its a pretty darn nice truck, towing AND trailering package not including a trailer receptacle not withstanding.
Drives like a dream. Flip it to 4 high on a dirt road and it handles the curves almost like its on pavement. Not why I wanted a 4wd, but definitely a nice plus.
First fill up at the pump was a bit disappointing at just over 12 MPG, but amazingly the second fillup jumped quite a bit to a little over 14. That included about 90 miles of pulling a 3800 pound boat and trailer.
I launched and loaded the boat on the dirt between the ramps at Fisher's due to low water conditions, and it handled it just fine. Never spun a tire. THAT was why I wanted 4wd. It's just enough. In fact I think I'll be able to stick with the stock tires indefinitely.
The factory CD/MP3 stereo is one of the best I have heard in a new vehicle. I hear sounds in music I was never able to hear in anything but a custom car stereo before. I haven't played with the On-Star, but I imagine it works pretty much like the On-Star in the Avalanche we just sold.
There is one little annoyance though, and its not very consistant. I hear an r r r r r r r r r r r sound every once in a while. Lasts for about 1-4 seconds and then stops. Sounds almost like a motor and pump kicking on and off for a couple seconds. If it was a motorhome I'ld think it might be an autoleveling motor. I've usually only noticed it cruising at steady speeds, but I did notice it once backing up at a slow speed. Its not very loud. In fact the first couple times I heard it I wasn't sure it wasn't just some kind of road noise. I know. I know. Brand new truck, just take it to the dealer, but I also know its almost impossible to get a mechanic (at least here) to ever duplicate an intermittant noise. If I could figure out what it is then I could tell them what to check. I have had much better luck getting things fixed that way.
