  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!

  Opinion on recent Used purchase 6.6 Duramax - 2005 GMC Sierra 2500HD
  By randy012796 - July 24 - 9:31 am

  Just bought this truck from my neighbor. 58,000 miles on a 8 year old truck. It is box stock and clean. I cleaned it up even more. I have never owned a diesel before or a GMC. This diesel is Awesome! GMC has a slightly better finish than the Silverado I sold. We tow a 33ft Keystone Ultra lite camper thats 6,800lbs like a dream. There all expensive and I dont know why the comman man would spend the money on a new one. Enjoy shopping and go clean used. Some mods in the future, good deals out there on used perf. parts

  Great - 2005 GMC Sierra 2500HD
  By greg - September 17 - 8:56 am

  I have had several of the old classic 2500 4WDs and this one is by far the best truck I have ever owned. The styling is so much nicer than Chevy. Only one little problem with the transmission so far. All my previous GMCs spent a lot of time in the shop for warranty work, but not this one! Build quality seems so much better now.

  The time tested truth - 2005 GMC Sierra 2500HD
  By dplind - August 23 - 10:00 am

  Ok lets start out that I have owned them all and I have owned a lot of trucks. My business is repairing trucks of all sizes and brands for large and small owners. I drive what I dont have to fix! Period! The GMC gives me power to pull my toy hauler and comfort on the long vacations. looks great and never lets me down

  2005 GMC 2500HD SLE Crew Cab SB 4WD 6.6L - 2005 GMC Sierra 2500HD
  By Larry Sinclair - July 11 - 7:30 am

  This 6.6L turbo with the 5 speed auto trans performs excellently whether driving empty or pulling a 30 RV. Interior is very plush (all the bells and whistles)and extremely quiet and comfortable on the road. The dash layout and field of vision behind the wheel is excellent. Added a bedrug and Pace Arrow bed-locker with power tail gate for security and improved MPG. Added ONKI brush guard for added protection from Colorado wildlife. This is a real truck for all occassions with added luxury and comfort!!! For 06 the manufacture has added 30 hp and 6 speed auto trans to an already outstanding rig.

  GMC SIerra HD Duramax - 2005 GMC Sierra 2500HD
  By Richard - May 9 - 7:43 pm

  This truck pulls a 30 foot RV travel trailer with absolutely no problem. Using the tow button helps slow everything down with ease. This truck is much more quieter than Dodge or Ford. It has lots of power and looks great, unlike its competition.

  Love of my life - 2005 GMC Sierra 2500HD
  By Roger - April 23 - 7:23 am

  Love the truck. Drove the Ford and the GMC and fell in love. Drives sweet. Tow a 10,000 lbs 5th wheel and dont even know it is there. Transmission is great uphill and down. Bose stereo is great. Heated leather seats and dual climate control are sweet. Would recomend this truck to anyone.

  05 GMC 2500HD Duramax/ZF-6 Manual - 2005 GMC Sierra 2500HD
  By ~jc~ - June 24 - 10:50 am

  I enjoy this truck. The diesel has a lot of pep. The manual trans. is nice after getting a feel for it. The build quality for my W/T is less than desired. Handling is excellent for a truck this size. Ride is smooth. It has some design faults (ex: windshield wipers rise only about 3" from glass, pain to work on) and penny pinching faults (ex: no sun tint on top of windshield). All in all, I recommend.
