  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.

  Keep Looking - 2005 GMC Sierra 2500HD

  I have the Duramax/Allison combination. It is a very sloppy running engine. Sloppy in that it is not efficient at burning the $3 plus/gallon fuel it takes to run her. She smokes and run your finger on the inside of the tailpipe and youll see what I mean. My guess is that in the hoursepower wars, GM spared no expense in trying to get ahead of the competition. They should have left the 0-60 nad quarter mile bragging rights to a more appropriate vehicle like the Camaro or Corvette. Im looking for a new owner for this one.

  Love this truck as well as the past 3 Gmc trucks this truck is very comfortable and reliable. we have had even a Ford mechanic admit that the quality of gmc far exceeds Ford.

  Its OK, but check out the Dodge too - 2005 GMC Sierra 2500HD
  By gmc driver guy - November 3 - 9:43 am

  The 05 replaced my 03, both Duramax, and I have to say that I liked my 03 better. I dont know what GMC did between then and now, but whatever it was, I dont like it. I test drove a Dodge both times and thought that they rode too hard and the back seat was too small. On the other hand, is it worth $10 grand to get a GMC that also rides hard and has a slightly larger rear seat that Im never going to ride in? To be sure, its a nice car, but Im starting to wonder if I shouldnt have bought the Dodge and put the $10 grand into my future Cessna fund. Come on GMC, for fifty grand you guys can do better! If you dont believe me look at your last 3 quarters sales numbers.

  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.

  Great truck - 2005 GMC Sierra 2500HD
  By terry - June 17 - 9:46 am

  I purchased this truck in April 2010. My first gmc. I love it. It has the duramax & Allison combo. Very powerful. It pulls beyond what I expected. I got this truck used with 81 thousand miles. Everyone tells me its just getting broke in. So far I like everything about this truck.

  Camper caper - 2005 GMC Sierra 2500HD
  By thomas - May 14 - 10:20 am

  This GMC drives nice and handles very well on the highway. it has ample interior room for the grandkids and 3 adults, along with enough space for camping gear. When pulling a 28ft camper, its pretty bouncy when empty. The back seat is split, and you can fold one completely down, or both, leaving a lot of space in the back and still room for 3 people in front with the fold down console. It has auto 4wheel drive to take over when roads are snowy, and plenty of power to drive next to the big boys. My wife even likes to drive it. I replaced the muffler with one that makes more noise.That was a mistake. At slower speeds that sound is evident in the cab. I like the truck, but it needs better gas mileage to really make it one to brag about!
