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.

4dr Crew Cab SLE Rwd SB (6.0L 8cyl 4A)
Truly a masterpiece of "poor" engineering. 2004 sierra 2500 with a duramax diesel and Alison transmission. Had to replace the intermediate steering shaft the first year. The vehicle constantly looses prime and shuts down. Here's the kicker . The oil pressure gauge flutters and the annoying chime rings constantly indicating low oil pressure. The cluster panel has been changed twice, the oil pressure sending unit has been changed three times. They even changed the oil pump? Still, no fix. This truck has been a nightmare from day one!

This vehicle became a nightmare after about 10,000 miles. First the steering shaft failed ... ? That's right, the steering shaft! Next the instrument cluster had to be replaced since the low oil pressure warning kept chiming. It still chimes uncontrollably after replacing the oil pressure sending unit three times, the oil and filter five times (when it didn't need it), and get this ... they changed the oil pump and the thing still chimes at will! The truck rides like a tank. Now the steering gear box needs to be replaced. There are less than 85,000 miles on this pig!

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.
