I have enjoyed this vehicle greatly. My biggest negative was the average in- town gas mileage of 12.5mpg with the 5.3liter engine. Had I known that ahead of time I would have bought the 2500 model with the 8.1 liter which gets almost the same mileage with 50% more horsepower and tons more torque. The body integrity is about what you expect from Chevrolet. When it falls off you can put it back on, if you can find it. I don't know of any other truck in the maketplace I'd rather have so when I buy again I look at the Avalanche first.
Looks, practicality, and reliablity
Tighter and quieter chasis, improve body integrity.
