4.8 V8 is tough, just as good as the 5.3 minus the extra torque. I test drove the V6 and found it to be poor. Wish I had a back cab at times, but the tonneau cover does fine when i strap things in. Bought this truck used with 20K on it. Haven't done much to it except air and oil filters/oil. The previous owner installed performance exhaust which roars and gives extra HP. I put on 17" 2007 avalanche wheels and 265 70 R A/T tires. Put on rear air lift suspension (airbags) and have been hauling anything from dirt, rock, stone, furniture, appliances, and tow a 5250lb boat/trailer. Its a half ton but with the bags i can easily load 1750 as i have scaled it at landscape vehicle scale.
RELIABILITY!!! Takes a beating, very quick, good on gas for its rated HP/Torque, shines nice when its clean when im out on the town
I wish the truck had sliding back window and the optional fold down middle seat organizer. In winter, about 6-12 times i wish i have 4 wheel drive but found it wouldn't be worth it. I load it with salt and it does fine.
