I have the extra cab, 4x4, step-side model, with 3.4 litre V-6 engine. This truck has a lot of pep and is extremely dependable. I bought it used 4 years ago and the only things I've had to replace are one u-joint, one brake caliper and two front brake rotors. I love the look of the step-side and still get comments to this day, even though it's pushing 10 years old. Highly recommended for purchase.
