My first diesel

Review

I never had a diesel before but my prior experience with gas trucks was tainted with getting 13-15 mpg. So I opted for the diesel with the allison. Wow. I get 19mpg average and on highway trips I average 21.5. I put about 31000 on it so far in 10 months of ownership and I have no complaints. The true genius of this whole setup is the transmission. In tow/haul mode it downshifts for you when you brake while matching revs. Really saves the brakes and instills total confidence in pulling heavy loads - skid steers, tractors, trailers full of blocks, etc. I get about 15-16mpg while towing on the highway. Great truck!

Favorite Features

Allison transmission is awesome and limitless power from the diesel. Very quiet on the road.

Suggested Improvements

Smaller tailpipe. People think I am trying to make a statement...

Review

At first I didn't like the styling, because it looks like a Ford. I chose the 6L gasoline engine in the 2500HD to avoid active fuel management in the 5.3L engine. With only occasional towing, the gasoline motor is a good choice for acceleration with less maintainence. The gas mileage is only slightly worse than I am used to with my Jeep Wrangler. The brakes are really powerful once broken in. Comfort on the open road is great. I bought the vehicle on the internet at great price, but it came without cruise control. I asked the local dealer if he could add it and they said "no". On my Wrangler, it was no problem because the wiring is already there, but GM doesn't do this.

Favorite Features

The brakes are real treat after my Jeep Wrangler, which had underpowered brakes and front rotors that warped consistently. The truck gets a lot of looks.

Suggested Improvements

Perhaps it is GM's policy to prevent upgrading items like cruise control and fog lamps - but for customers like me who buy a unit off the lot, I would pay a reasonable price to get the factory equipment installed by my local dealer.

GMC Duramax

Review

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. It's 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.

Favorite Features

6.6 Duramax and Allison is great combo very strong. Fuel mileage excellent, 15.8 in town 19.6 on highway.

Suggested Improvements

More interior room and rear air vents. No room for larger tires on front.

Review

Great truck! The Duramax towed my 31ft Airstream on a 5000 mile trip without any problems. The truck was very stable and had lots of power to spare in all situations. Gas mileage was around 12.5 mpg towing and 17 alone. I hope for better mileage after the diesel gets broken in. I expected at least some problem to show up on the brand new truck but am pleased to say everything is working perfectly.

Favorite Features

Power of the Duramax and the Allison transmission - perfect for towing.

Suggested Improvements

The one bad feature in my view is that the 2500 crew cab with short box only comes with a 26 gallon fuel tank. Not nearly enough fuel capacity for a big truck with a diesel engine especially when towing.

Review

One of the best trucks I've 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.

Favorite Features

6.6 Duramax engine,6 speed Allision trans. Interior comfort, and fuel mileage.

Suggested Improvements

Cab handle on drivers side would help.

Review

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.

Favorite Features

Suggested Improvements

A better console area that has a lid that closes. The console with no lid makes letting the 3rd passenger ride pretty inconvenient.

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.

Favorite Features

6 speed transmission and the electric sliding rear window.

Suggested Improvements

Trailering wiring harness should come with adaptors for various configurations. Floor mats should be heavy duty

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!

New dash, everything

Review

Traded in Ford, Bought the new 2500HD. The first thing I noticed was the awesome interior, The stock 6.0 with the auto 6 speed was next to put a grin on my face, the big block power out of that little motor is amazing. I say to all who are interested, The new GMC Sierra is an awesome truck, with plenty of power to do what ever you would like!

Favorite Features

The whole truck!

I haven't come across anything I didn't like.

The good, the bad and the ugly

Review

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.

Favorite Features

The back seats fold down for an incredible amount of room for either my 2 German Shepherds, groceries, horse feed or whatever. The Duramax is great. Lots of power and quick acceleration making it a great towing truck.

Suggested Improvements

Exterior design needs updating. It is seriously ugly. The low profile seems very dated, and clearly GMC has not kept up with the others in style. Put the correct tires on a HD truck! Needs hand grips on the driver's side-a serious omission. Redesign seats to include lumbar support.
