  GMC 2500 HD/ Durmax Diesel - 2004 GMC Sierra 2500HD
  By tabinmn - March 24 - 10:00 am

  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

  Dons Review - 2004 GMC Sierra 2500HD

  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.

  BUY ONE!!! - 2004 GMC Sierra 2500HD
  By LUV my Duramax - October 25 - 2:00 am

  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 doesnt hesitate with anything, and the allison smartly downshifts when slowing down to reduce brake wear. This truck is also the quietest diesel Ive tested, when comparing the "BIG 3". At anything above 50mph you cant even notice youre running a diesel. ...every time I drive it...I like it even more...nuff said.

  This truck is awesome. We pull a 5th wheel camper and it pulls it like there is nothing there at all. Great truck.

  Bought Brand New 3 months ago and now have just under 10K miles. The Duramax is all that and more. Excellent Truck!! Not one problem so far!! Ride Quality is awesome for a 2500HD Truck!

  Diesel is wonderful - 2004 GMC Sierra 2500HD
  By E. Daniel Shoemaker - October 31 - 10:00 am

  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.

  4dr Crew Cab SLT 4WD SB Duramax/Allison - 2004 GMC Sierra 2500HD
  By Michigan Mike - January 17 - 10:00 am

  This is my first pickup. Used to own a 93 Suburban. Traded an Acura CL Type S for this truck. Surprisingly good build quality. After 1500 miles, no problems at all. In the Acura I had to replace the front seat and the sunroof after this many miles. Wish that the OnStar GPS system could be hooked into a 3rd party navigation system with a screen and DVD. Performance (acceleration, braking) is great, though Ive not yet towed anything. Heated seats are better/warmer than those in Acura. No complaints!
