2004 GMC Sierra 2500HD 4dr Crew Cab SLT 4WD SB (6.0L 8cyl 4A)


I purchased my truck about 3 weeks
ago, and have put 1800 miles on it. I
absolutely love the Duramax/Allison
combo. Anything with this setup will
drive like a dream. The Duramax
doesn't hesitate with anything, and
the allison smartly downshifts when
slowing down to reduce brake wear.
This truck is also the quietest diesel
I've tested, when comparing the "BIG
3". At anything above 50mph you can't
even notice you're running a
diesel. ...every time I drive it...I
like it even more...nuff' said.

Best Features

Duramax/Allison combo.; heated, folding, dimming, and turn signal outside rearview mirrors; Excellent fuel economy for such a large truck (16/21)

Worst Features

..add propellers on roof to make it fly vertically too; Better fuel economy always helps, but already class leading for this truck. Must add steps for entrance/exit (running boards..nerf bars, etc.)!!
