Great truck with Z71 package. I love the pushbutton 4WD. You can have it in auto 4WD for slippery conditions in snow or hit 4wd Hi or Low and have a full time 4WD with locking differentials. All 4 wheels will drive through mud and sand. Out performs Ford 4WD trucks every time. Fold away mirrors are great for car washes. I have black and looks sharp when clean. The 5.3 Vortec V8 has plenty of power and good gas mileage (18.3 mpg) in town.
Good truck

I bought this truck about a year ago. It was previously owned and I was the second owner. I shopped around looking at all of the "big three" offerings, I even checked out the Tundra and new Titan. I drove all of them. The Dodge was fastest (Hemi Powered) The Nissan Seemed to be the most Techie, Ya know gadgets and such. But the best overall was this GMC, Towing power is top shelf even with the baby 4.8 ltr. I still tow nearly 7000 lbs and it's rated for even higher, not too shabby for a 1/2 ton, If you need to tow more, then obviously you'd be 3/4 ton shopping. But all things considered, The GMC has the all around best value, Mabye not the best in all areas, but certainly superior in most.
Almost perfect

I have allways been a GM man, and this truck doesnt disapoint. The heated leather captains seats with two person memory are very comfortable. The steering wheel controls for the Bose stereo are great. Some interior wind noise though, and the suspention is very jumpy on the concrete highways. It is in the shop as I write this having the tranny pulled to find out why it started shifting hard from first to second gear at 15900 miles.

This truck has the potential of being everything I want it a truck. It offers a very smooth ride and the leather seats are some of the most comfortable I've sat in. A friend recently purchased a comparable Ford model. After riding in my truck, he's quick to point out the superior ride and comfort of the GMC. Disappointment: I recently scheduled my 2nd service visit because the outside temp gauge constantly reads in the 90's if the temp is above 38 degrees. There are rattles in the dash. This is the 4th GM truck I have owned and this is the least smooth transmission of any of them.

The comfort of the ride is outstanding. Able to pull trailers with ease. Not bad gas mileage for size of vehicle.

This vehicle is very fun to drive! It's comfortable. I drive a lot and all I have been doing is oil changes. I have 110,000 miles on this vehicle and nothing mechanical has happened to it

Great truck, only 1 issue. With a little over a thousand miles, sounded like loose sheet metal under the truck. Ended up going back to the dealer 6 times before I went to another dealer. Found out it was the A/C compressor. Mechanic stated that it would build up too much pressure. Thank goodness I didn't put it off. Over $2500 in parts & labor. Not a single problem since. For such a big truck, get wonderful gas mileage. Only one thing I would change... get better viewing side mirrors. Lots of blind spots with the OEM mirrors.
Love my truck... so far

In January I bought a 2003 GMC Sierra 1500 SLE with the trailering package and the Z71 off-road package. The truck is quite as a church mouse on the inside and runs beautifully. The ride is firm, like a truck, but not so stiff that you have to visit your dentist and have your fillings put back in weekly. Visability is very good and the inside is extremely comfortable (including the back seat). Transmission shift isn't always smooth as GM silk and there is some growl from the front end in 4WD... time will tell if these are normal or not.
Best GMC Yet ! There is no competition!

I have owned ford, Nissan, and GMC. My last GMC (2001) was a great truck (SLE ext cab 4x4), but it needed a larger engine and a leather interior. The 2003 was what I was hoping for. Plenty of power, great ride, creature comforts, and can still haul two yards of topsoil. I can look good taking my wife out to dinner and still get the rugged use of a truck!

GMC trucks are strong and reliable if maintained properly. The base model, 4.3L V6 I own has 187K miles and still going strong. No drive train problems, economical on gas, and a comfortable work truck.

Bought this truck used in 2010 with 65,000 miles. I now have 144,000 miles and with the exception of replacing the water pump, brakes, a couple of batteries and some minor body work (all of which I view as normal maintenance) I've spent little money on it. As you can see I haven't driven it a lot of miles and since my retirement 10 years ago I only put on about 4000 miles a year. I change motor oil every 2000 miles and transmission fluid and filter every 30000 miles. I plan on keeping it until they take my keys away from me. lol.

Poor Ride with wheel vibration

After about one week of driving, the truck began to vibrate excessivly especially on concrete freeways. Took it in 4 times, each time the wheels were way out of balance. They can't figure it out. They think that maybe the tires are moving on the rim. These are Bridgestones on aluminum wheels. It turns out that you may get Bridgestones or Firestones(same ones recalled by Ford) depending on what they have laying around at GM. It is made worse by a poor suspension design that does not perform well at highway speeds. At this point the tires are still out of balance and the dealer doesn't know what to do or what is happening.
THIS IS THE ONE!!!!!!!!!!!!!!!!!!!!!!!!!

I traded in a 2002 Z71 silverado for this 2003 Z71 Sierra(new). I was suprised to find the same annoying rattles that I had fixed on my 2002. The windshield rattles, which is because of the exterior window trim. The doors sqeaked, which is because GM is to cheap to oil their doors at the fatory. Other than the annoying issues that took one trip to the dealership I couldn't ask for a better looking,riding and performing truck. Hopefully GM doesn't decide to cheapen it up down the road!
