I have the 2500HD 6.6L Diesel 4x4 Crew Cab SB. This is my third GM 4x4 truck, but first diesel. I tow an RV and put dirt bikes in the back and it drives like I have nothing attached and nothing in the back. I can accelerate going up hills on the freeway fully loaded towing the RV. The interior noise is quieter than my wife's Chevy Blazer. The stereo absolutely rocks, and the seat heaters are so nice - even in San Diego CA! This is the best truck ever made.

Great truck, still getting used to the
new front end grill( I liked 99-02 best)
I previously owned a 2000 z71 sierra
slt. Just bought 2004 SLT 2500 crew
cab 4x4. They dont include under the
hood courtesy light, they eliminated
one of the cigarette lighter power
input. the 2004 has 6l vortec which is
a huge pig compared to 5.3 vortec in my
old 2000. the new computer stuff is
pretty cool. I am getting on average
10mpg on the 6 liter, I used to get 18-
19 on the 5.3 motor. The first thing to
go will be the air cleaner swap with an
Air aid or K&N type of element.
dramatic horsepower and fuel economy
increases should be expected.
