  Duramax Rules - 2007 GMC Sierra 2500HD
  By mARK - December 10 - 12:33 pm

  I love this truck so much! more quiet then a Dodge or Ford Diesel. This truck could pull a battleship with its strong Allison transmission!

  Clean GMC - 2007 GMC Sierra 2500HD
  By Jack - October 2 - 6:23 pm

  Bought the 6.0ltr WT version two weeks before leaving Maryland. Installed cruise control and hauled 5500 lbs on a 16ft tandem trailer and 1000 lbs in the bed. Averaged 16mpg on Hwy after tuning with the Diablo Predator using 87 octane gas. I have the 4:10 HD posi-lock rear. I average 12-13 mph in town. I would have liked the 6spd Allison transmission.

  The good, the bad and the ugly - 2007 GMC Sierra 2500HD
  By carlotat - September 18 - 6:03 am

  The GMC is a replacement for my stolen 03 Ford F-250 Powerstroke. I bought the GMC Sierra on the recommendations of others who had purchased it, against my better judgment. The Sierra has some nice features, particularly the interior arrangement. Everything is within easy reach and well laid out. The Duramax and Allison are a great duo, and can easily haul my horse trailer up any hill with ease. My biggest problem with the Sierra is the puny O.E. Bridgestone tires. Why GMC chose to put highway tires on a HD truck is beyond me, but after slipping and sliding my way through a snowy and muddy New Mexico winter, and with only 6200 miles on the tires, I replaced them with Michelin M/S. Huge difference.
