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


Absolutely the best truck I have ever
owned. During it's maiden break-in
run I got 23.8 mpg. When engine is
broken in mileage should be even
better. I drive between 55-65 mph and
this seems to be the "sweet spot" for
performance. Got it to haul our slide
in camper and this will be no problem
now. (Not like our 91 Silverado which
on it's best day with only one person
got 20 mpg)

Best Features

Roomy cab, comfortable seats, fine instrumentation. AWESOME diesel engine! Terrific mileage for a vehicle of this size and power. Lots of amenities.

Worst Features

Would be nice to have more switched power outlets under the dash for accessories. (Have tested with power meter and only found one). Watch out on washboard roads - vehicle suspension will let you know immediately that it is a 3/4 ton. Only complaint - pricey!!!
