I bought this truck 3 years ago with 120000 miles on it and it just purrs. Smooth, quiet, comfortable and even with all those miles it still doesn't burn or leak any oil. I haul a 260 gallon water tank in the back and it doesn't even phase the old girl. Just a great truck!
great truck good at hauling. very spacious and comtorble. gas mileage is good for a truck. had this truck from new to 180000 miles now original motor still runs very smooth as does tranny, and everything else. the only repairs i had to do so far on this truck was o2 sensors about 40bucks each a crank angle sensor about 50dollar and a output shaft seal on the transfer case, i did the work myself. other then that routine maintance and she'll run strong for a long time. i would diffently buy another in the future if needed.
The Sierra has a comfortable ride with tons of room in the front seat and also in the back. I like the short box. It was just enough for everything I was hauling and kept the vehicle length shorter. The 8 cyl give the Sierra great pick up. However the gas mileage is quite low. I have owned it for three years (48,000 miles) and have not had one problem with it.
Everything about this truck is amazing, from the way it drives, to all of its abilities, towing, hauling, etc. The most impressive thing is the Autotrac 4WD system, I have off roaded with it in the snow, and never slipped a tire, even in over a foot of snow!
GM could do better at designing this vehicle to ride smooth without a load. When loaded in the back it rides great, but with an empty bed, is is very choppy on the least uneven road. Only about 30 lbs in the rear makes all the difference, perhaps a tailgate weight or something. All in all, this is a great vehicle. A little less room than my Avalanche, but still very comfortable for 4 normal sized people. Looks great (mine's black). Gotta have the leather!
