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

Review

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)

Favorite Features

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

Suggested Improvements

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!!!

GMC 2500 HD/ Durmax Diesel

Review

I appreciate the diverse choices when purchasing vehicles but choose to pick GM d/t the ability to find anything from fast sports cars, Corvette, to tough Durmax Diesel. The current Vehicle of choice is as described above and I wouldnt tow w/out the performance of the GMC Sierra 2500 HD Durmax Diesel. Not only does the beautifully engineered design look great driving down the highway but also performs outstanding w/absolutely no problems. This is my 3rd Duramax and would recommend it to any serious driver that needs a truck w/towing capacity. Not to mention gas milege...what truck of this capacity can get

Favorite Features

Tough Duramax diesel. Great gas mileage. Good design both inside and out. Options are endless

Review

Traded in my 96' GMC 3/4 ton Suburban, w/ 454 Vortec engine for this new crew cab, Duramax w/ Allison transmission. Wow what a difference in towing power. Previously driving over mountins into Prescott and Payson, from the Phoenix area, we were lucky to keep up 35mph. Now, wow, 65mph over the same roads and mountains, towing the same trailer. Diesel milage is better than the gas by about 5 to 6 mpg. Wish the Suburban had this engine/trans.

Favorite Features

All good. Love the controls on the steering wheel.

Suggested Improvements

Add in GPS. Could really use it for work. $47,000 truck ought to have one ... don't you think?

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

Review

The experience of getting better gas milage with the 6.0 motor in the GMC as opposed to the 4.8 in my Chev, makes me wish I had bought the Chev with the 6.o instead of the 4.8. Factor in the added pulling power, makes it far better. I highly reccomend getting the 6.0 in either model truck.

Favorite Features

In one word, the motor.

Suggested Improvements

It will be hard to improve, other than add more cushion to the seats to compensate for the harder ride in the HD series.

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

Review

I am pleased with my purchase at this time. It tows as is expected for a truck with its power- it is capable in the woods and farm as well as on the highway-- though the fuel economy is a jolt. But then again it is alot of weight to move.

Favorite Features

xm radio- front bucket seats and espically all of the computer business and personal functions that are on the display.

Suggested Improvements

maybe offer a quadrasteer on the 2500 HD models, larger and more aggressive stock tires-maybe 285's

Review

Thus far it's proven to be what was expected. I do like the pick up power and acceleration power, the turning radius needs to be inproved. Another plus would be to install a rear window that is fuctional. Heat controls for the rear needs installed. Overall the performance, handling, and appearance are what I' expected. I've named it the HULK, it's big, it's green and it's powerful!

Favorite Features

Color, handling, braking, power and fuel milage. Quite, warms up fast, dural max motor!

Suggested Improvements

Improve turning radius, rear window fuctionality (split or roll down), need anti theft system installed from GMC, Stylish wheels, option on step boards without increase in price. More colors to chose from. Dura max cost to high.

Review

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.

Favorite Features

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

Suggested Improvements

..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.)!!
