  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!

  This truck is by far the best combination of utility, comfort, and performance I have experienced. I love the truck and highly recommend it to anyone in the market for a new pickup.

  Very Powerful. Very Comfortable - 2007 GMC Sierra 2500HD
  By Dennymax - January 21 - 10:23 pm

  I have been driving my truck for about a year & a half. I was excited at first because it was new. Now I am still excited! The Duramax/Allison is a just a great design. There is so much power for towing. This truck should come with a warning light reminding you that a trailer is attached because you will forget that its there! No more "white knuckle" driving while towing, built in brake controller works really well. This is just flat out awesome! The seats are like flying 1st class, interior is much improved. SLT has all the goodies, more like a luxury car, except its a truck. Why have a car anymore?

  GMC Duramax - 2007 GMC Sierra 2500HD
  By glenn helms - August 26 - 10:43 am

  I purchased my GMC a few weeks ago so far so good. I had a Ford F-350 powerstroke with 7.3. The GMC is small in the inside compared to the Ford. The GMC has a lot better fuel mileage but seems to be too light to handle heavy trailers. Its not short of power it will smoke my Ford easily. My biggest complaint is lack of interior room. GM still needs to do their homework on that. The quality is not matched by Ford or Dodge in the interior and standard accessories, but I think Ford is heavier duty than GM for all out abuse on the farm or on construction sites. In about a year i can tell the truth because I know Ford can hold up. Curious to see if GMC can.

  Awesome 2500 HD - 2007 GMC Sierra 2500HD
  By Eric - October 26 - 8:50 am

  Was driving a 2006 2500 HD SLT and loved it. Just traded and picked up my 2007 2500 HD SLT. Wow, what a huge change. Feels like I am driving a luxury large SUV. Totally updated inside and out. Inside much better and up to date. Quiet ride. Feels larger than 2006 when driving. Smooth. Recommend this one!

  Professional Work Truck - 2007 GMC Sierra 2500HD
  By Ralex - October 5 - 10:50 am

  In "07 I needed a truck to tow a 7000lb 14x9x9 box trailer in western PA. I test drove em all and fell in love with a Ford until I learned GM had the most torque, hp & mpg. Found a GMC L82 with all towing packages. I tow 5 days a week and avg 9.5mpg city and 15 on the hwy at 62mph or 2k rpm, above 65 mph the aero drag zaps the mileage to 10.5. The PA hills takes another mpg. Without my trailer I get 15 city and 21.5 hwy. I love the performance and the bucket style seats, it feels like a Camaro on steroids. Get compliments every where I go and with 30K miles Ive been everywhere.

  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.

  GM has lowered its standards! - 2007 GMC Sierra 2500HD
  By RPS Inc. - August 17 - 8:43 am

  This truck has wasted tons of my time and hard earned money. It seems the only things that have not failed yet are the engine/tranny. I also own a 2002 of the same model that I find to be 100X better quality. These are just a fraction of my complaints/problems I have dealt with on my 2007 sierra 2500hd (these issues surfaces with under 40k on unit)>>Exhaust failure, idler/pitman arm failure, hvac problems, bad factory rim, leaking oil/tranny cooler lines, cruise control works when it wants to, thin flimsy body panels, 4wd disengagement issues, tailgate handle failure, bad airbag wiring harness, door hinge failure......I have always considered GM the best that the USA can offer..Not anymore!

  Love it - 2007 GMC Sierra 2500HD
  By DM - October 10 - 7:10 am

  One of the best trucks Ive owned. Was looking at another brand until someone told me how good the fuel mileage was with this truck. Somewhere around 18 to 20 mpg highway driving. The 6.6 Duramax diesel/6speed Allision trans is one awesome drive train. Plenty of power to spare. Shifting is very smooth. Interior comfort is excellent. The dual zone auto temp. control, leather power bucket seats keeps comfort at the front in this vehicle.I would highly recommend this truck to anyone wanting muscle and comfort.

  I really like the bigger roomier cab on this truck. It tows my camper with ease and has lots of power to spare in the 6.0L engine. I do wish it got just a little better gas mileage but with power comes consumption. I would buy it again I like it so much.
