  GMC 2500HD Diesel-Automatic Crew LB - 2005 GMC Sierra 2500HD
  By Steve - January 21 - 9:00 pm

  WOW....What a fantastic Truck! I have a 1995 FORD 250 Gas (70K Miles), and a 1994 GMC Gas (113K Miles). The 2005 GMC is comfortable enough and even with the longbed easy enough to drive and park that I leave the car in the garage and use the truck for work and play. When it comes to the work portion it is one powerful, competent truck. I wish the side mirrors were the size of Fords. All the manufacturers need to install a tie down hook in the front middle of the truck bed. Metal around rear wheels in truck bed is too thin in the GMC. GMC needs a radio mute button on the steering wheel. Needs additional LARGE cup holder for the driver in center consol. Cup holders too close together.

  One Sweet Truck! - 2005 GMC Sierra 2500HD

  This is a wonderful truck. It rides so smooth you think you are in a Cadillac. This is the second GMC I have owned and I dont think that I would own any other truck!

  Very nice truck. Lots of power for pulling my 35 foot race trailer. Good on fuel about 21 highway 18 in town. I put the banks 6 gun chip in it. Very fast. Sounds good and has lots of power

  Better than expected - 2005 GMC Sierra 2500HD
  By Car Guy - May 5 - 10:00 am

  So far this vehicle has exceded my expectations as to power and towing ability. I could not believe I was passing other vehicles as I was going up hill pulling a 20 trailer with a car inside the trailer. The gas mileage continues to improve as the vehicle breaks in. I love driving this vehicle and I am confident in its reliability.

  What a fun beast! - 2005 GMC Sierra 2500HD
  By Stuart Schotte - February 23 - 5:03 pm

  Bought it new last month. I had a problem with the overflow tank leaking into the wiring harness and ruining a control module. 10 days in the shop and then the radio had to be replaced. Some gremlins in the electronics. If it is all fixed this will be my dream truck! I have the diesel. I am getting about 17mpg at 70-75 on the highway vs 14 for my 2002 Chevy K1500 w/ the 5.3 ltr. This thing will go straight up mountains without downshifting! What a beast! I was towing about 9k lbs behind the Chevy. I cant wait to hook "Max" up to the trailer! XM is nice for trips too. I have the buckets in front and the console encroaches on my leg when driving (Im 64"), but you get used to it!

  Hi Oh Silver - 2005 GMC Sierra 2500HD
  By dkwalker25 - August 9 - 7:10 am

  i love my pickup, hauls my 40HP massey with bucket and brush hog like its not even there. with banks big hoss bundle it hauls balls and doesnt think twice. awesome truck wouldnt give anything for it. its dependable, and with all the mods it catches eyes everywhere i go. as of now, until ford puts out the 6.7L would only recommend a duramax. cummins is good but everything around it is crap and rides like a semi. duramax is king right now. i just cant say how much i love my pickup.

  Love this truck - 2005 GMC Sierra 2500HD
  By Gordon - August 22 - 10:56 pm

  Love everything about this truck. Build quality is the best I have seen in years. Will pull a heavy trailer all day and it is easy to forget it is even behind you. Mine has the Duramax diesel and Allison transmission.

  Excellent truck for me. - 2005 GMC Sierra 2500HD
  By William M. Lynch - July 28 - 12:50 pm

  This is by far, one of the best, if not the best truck Ive ever purchased or driven. The interior (seats) are a little stiff (leather), but not an issue overall. The gas mileage is a little rough, but hey...I knew that going into the purchase. I love my truck!!!

  Duramax Diesel Love IT - 2005 GMC Sierra 2500HD
  By Jim Bewley - July 6 - 9:36 am

  This is the Duramax Diesel 2500 HD and I absolutely love this truck. I wouldnt trade it for any vehicle in the world. It pulls my 30 1990 very heavy camper like a dream, even in the mountains. I cant say enough positive about this truck.
