I have had this truck for a month now and have about 1100 miles on it. No problems so far. Getting 15.9mpg average and most is city driving. Great power, great looking, and great fit and finish sold me. I keep my vehicles about 10yrs and after the last silverado I owned(2002) turned 132000 miles(trouble free) I decided to trade up to the crew cab with all-star package. This truck is a huge step up in performance and features. Especially like the bluetooth feature and the updated interior quality. You really can't go wrong as these trucks hold their value and are very capable vehicles.
I do not have the LTZ, I have an LT Z71 4x4 with the 5.3 L and 6-speed tranny (3.08 rear end).
I have had the truck just under two months and have 6200 miles on it and am very pleased so far.
All of these miles have come with a 900-1000# payload in the back (permanent vet box) and the truck gets 15.5-16 mpg with this setup (I do not drive very conservatively).
The truck will downshift into 5th and 4th on steep grades.
With the z71 suspension and the 1000# payload, I have not had to add any suspension reinforcement.
The rear end sits down a bit, but not even to level, let alone noticeably squatting.
Towing heavy trailers with the payload does cause trailer sway, but I don't tow much.
This is my first Silverado and it exceeds all of my expectations.
The ride and handling is far superior to the mid-size pickup I traded in on it.
The interior is comfortable and very roomy- I can fit six adults easily.
Power with the 5.3L and 6 speed is plentiful and makes this truck fun to drive.
It gets identical fuel mileage to my former mid-size too.
The frequent shifting of the 6 speed took some getting used to but the shifts are mostly unnoticeable and power is always on tap.
The autotrac 4wd is fantastic in the snow.
Overall I'm very impressed with the truck.

I put a good 10,000 miles on it while in Alabama and it performed well.
The real test was to come - I had it shipped to Alaska, upon moving, and have put 6,000 Alaska miles on it since being up here during one of the worst winters in history.
I have to say, this truck performed flawlessly.
Although, per the dealership here, it is suggested to not use AUTO 4x4 as it will eventually ruin the 4x4 - Just keep it in 4 High in inclement conditions.
Ice, Snow, Mud, Slush, not a problem for the Silverado.
Ya, the interior sucks compared to Ford, but I dont care to much.
Love the huge center console/elbow rest.
Gas mileage in AL and AK have been consistent at 15.4 on cruise, all HWY miles.
Have had truck for 5 months. First truck I have owned but won't be my last as this truck is everything and more than I expected.
The ride/comfort is equal to luxury cars I have owned and currently own. The best MPG I have been able to attain is just shy of 20 going 72 MPH for long stretches- but I'm not complaining; I didn't buy the truck for MPG reasons.
