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.

Ok let's 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 don't 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

Was considering the Dodge Cummins for it's tough reputation but couldn't swallow the tight back seat for a growing family. A friend had the Chevy Duramax and I haven't looked back since. The GMC Duramax and 6 speed Allison tranny are incredible. Quiet ride, plenty of room in the back seat, power a plenty to pull the bass boat with a camper on top. With or without a load, city and hgwy driving we still average 18 mpg, and at least temporarily diesel is cheaper than unleaded in my neck of the woods. Absolutely no buyers remorse with this truck. Two thumbs up all around.

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 it's competition.

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 that's 6,800lbs like a dream. There all expensive and I don't 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 Update: 85,000 mile now....still 100% satisfied. Many want to buy it from me. Not for sale! Great truck.

I have bought GMC or Chevy my entire life excpet for 2 Fords I bought that were cheaply made, broke down with either engine or A/C problems. The Fords were cheaper with certain truck models but with the truck workmanship and problems with dealers fixing warranted items. I stayed or went back to GMC. The 2500 H/D 4WD Crew Cab I bought is the best GMC or Chevy had to offer. They are over priced but working with the right dealer you might find one you can live with.Some of the Dodges looked nice, but the way they are priced and the overall sales depts over the country are not customer friendly, nor will they work with you on the price.Its thier price or you walk out. Forgien trucks or just that .

The GMC HD Duramax is by far the best diesels you can buy on the market. I recently compared the duramax to other cummins and powerstroke diesels and it out performs them from towing to payload to the comfortablility of the ride. I recently compared the duramax 2500HD to the Ford f-450 and I compared everything and the thing that stood out to me was that the GMC maxed out at 16000 pounds and the Ford pulled only 14000 and the ford was twice its size and still the duramax was the best. So weather you are a ford, GMC, or Dodge guy duramax is the diesel to buy.

It's a love/hate relationship between me and this truck. I first fell in love with the outside design. The front view has the same appearance as the Denali. It rides high and has a very aggressive look. It has plenty of power and has yet to be challenged by any load have had. The 6.0L is one of my prized possessions. Most of the of the negative comments here should have been expected, I understand. It sucks gas. I'm averaging around 14 MPG. It offers a bumpy ride. The dash board seems cheaply made, with thin plastic. The rear end can get loose quickly on wet surfaces. The power steering box went out twice. 17 inch rims on a truck of this size is an injustice.

The new Duramax engine is better than I hoped for. It has tremendous acceleration, quieter than ever and reminds one of a sports car. The 6 speed Allison has smoothed the shifting much better than the 5 speed Allison. Cruising at high speeds is unbelievable for a heavy duty truck. This is my third Duramax 4WD 2500HD and they keep getting better.

Better fuel mileage, reliability and smoother suspension than the comparable Ford. However, position of side view mirrors creates dangerous blind spots. Cup holders in front difficult to access. Front middle seat very uncomfortable. Front passenger seat lack of foot/leg room r/t air box, this lack of space is even worse when there are passengers in back seat and you have to move front seat forward to allow more space for them. Lack of leg space for back row and you have to turn your foot sideways to get in/out of vehicle due to the lack of space between the seat and exterior section of vehicle where door attaches. There's more. Overall this is NOT a vehicle for a crew. This is no CrewCab.

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.

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 you'll 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. I'm looking for a new owner for this one.

This diesel was an upgrade from a gas Dodge RAM1500. Pulling a 7,000lb trailer now seems effortless. Turbocharger takes a long time to engage and gas mileage wasn't as good as I'd expected for a diesel- about 12.5 pulling trailer which is disappointing since over 20 without. Just had 3 injectors replaced under 100K Duramax warranty which I believe was a known problem in all GM diesels from 2002-2006. No recall, of course! No significant change in power or mileage with the new injectors. I hate that GM always adds a $95+ "diagnostic fee" for the computer hookup with any service. Also- computer's trip timer hasn't worked since purchase and the stereo speaker sound is absolutely awful.

Fuel mileage is poor at best. Engine surge and hesitation. Driveability is very eratic. Vehicle runs hot, fan runs excessively. Tranny and engine temp gauges always show 210 or better. All this while running vehicle empty. When towing all of the above is off the charts. GM answer is that all is normal.

I have always wanted to own a new vehicle so last fall I decided to purchase my all time favorite vehicle, the GMC Sierra. I bought it over the internet because I knew what I wanted, I picked up the vehicle and drove it home. I was amazed at the lack of HP and gas mileage. Since this was my first new vehicle I didn't know all about the break in process. It took 2 weeks for the HP to show up and the fuel economy to increase. In the meantime I was entertained by the XM Radio that will be an option in every vehicle I purchase from now on. The interior of GM vehicles still have the working man's look to it, but it is hiding an amazing array of features.

So far this vehicle has exceded my expectations as to power and towing ability. I could not believe I was passing other vehicles as I was going up hill pulling a 20' trailer with a car inside the trailer. The gas mileage continues to improve as the vehicle breaks in. I love driving this vehicle and I am confident in its reliability.

I drove them all. GMC still offers the 'work truck' and although it might be too spartan for some, I found it to be the right balance of form and function. Also, if price is an object (isn't it always)this baby rocks. I use my trucks like, well, trucks. And if I had had to spend $40,000+ on something else, I might be guilty of babying my truck. Then why by a truck? I had a bedliner sprayed in, and now it sees full duty as my primary working, boat pulling, camping, wheeling vehicle. Fit and finish are very nice. Plenty of power with the 6.0L. Even the cloth 'bench' seats are comfy.

I had an '04 2500 HD and liked it enough that I traded it for an '06 equipped the same. The employee discount was the reason for the switch. It does have a stiff ride, but then, it is a HD instead of a softer pulling 1500. I can pull my 3,000 lb steel horse trailer with 2 horses with an average weight of 1,000 lbs each, and I do not know it is behind the truck. No matter what type of terrain or road condition, as long as it isn't ice covered. We havn't had snow or ice so I havn't had a chance to put it to the real test as yet, other than pulling the horse trailer.

I am a farmer and I use my truck very hard. But I do take very good care of it. I like the feeling that I know I can rely on my truck. I also hunt with my truck and I couldnt ask for a better, more dependable truck. I never yet have gotten stuck with it or ever had a problem with it stalling or anything like that. Ocassionally I take trips to northern Maine. I live in Southern Connecticut so it is quite the ride. Although with my Duramax deisel engine I can go there and back and have enough fuel to drive around. I like the chrome on the front bumper ecspecially it really makes the truck look solid. I know people that own Dodge trucks and Ford trucks and my truck definetly more dependable.

Purchased this truck on 5/26/05. Had it only three days and had to put it in the shop for automatic transmission repair. It was in the shop for four days. First gear went bad after only 500 miles. It doesn't turn as close as my old Yukon but it is a larger vehicle. The engine is powerful. I can't even feel my trailer. I like the looks. For an XLT it doesn't have some of the options I thought it would have. ie. lumbar seat, rear A/C. I really like the truck. I'm just disappointed with the transmission problem and the lask of service from the dealer. I'm just waiting for something else to break. It also is a little bumpy. Maybe that's normal.

The '05 replaced my '03, both Duramax, and I have to say that I liked my '03 better. I don't know what GMC did between then and now, but whatever it was, I don't 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 I'm never going to ride in? To be sure, it's a nice car, but I'm starting to wonder if I shouldn't 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 don't believe me look at your last 3 quarters sales numbers.

I purchased my GMC 2500HD SLT 4x4 with the 6.0 engine and locking rear differential to haul my new 8.5 foot slide-in camper. I picked the camper up at the factory and proceeded on a 4500 mile test run. Encountering heavy cross winds in the Dakotas and steep passes in the Rockies had little or no effect on the draiveability of the truck or it's performance. The camper weighs 2370 pounds dry and yet the truck responded with little difference than with an empty bed! Mileage on the way to the camper factory in the midwest ran between 14-16,at speed limit empty and 11-14 with the camper loaded.

Replaced my 2001 8.2 L Silverado HD crew cab with this truck. Basically the same vehicle, but with a 6-speed Allison tranny and a Duramax diesel. Compared to the older truck, it has a little better build quality, (not quite up to Japanese standards, but very good--not enough to really matter) vigorous acceleration, and incredible torque. Diesel is surprisingly quiet, and GM is less "trucky," compared to Dodge and Ford. Mileage averages around 16-19 mpg, with 12 mpg towing a 35ft. 5th wheel. Rugged enough for big truck jobs, but civilized enough to use as an everyday vehicle. Nice balance. Reliable, handsome. Quantum improvement over diesels even from a few years back.

I bought my Duramax Diesel 2500 Hd crew cab to pull a 36 foot fifth wheel. There is plenty of power; however, have had a few problems. The speedometer failed at about 60000 miles and had to be replaced. I have read that this is a common problem but there is a class action lawsuit and I plan to turn in my 478.00 receipt and hopefully get reimbutsed from GM. The engine light came on and paid to have the code read which was relatively meaningless but haven't had any more problems with that. I added a Superchip which is amazing how much perfromance improvement. Have heard that some people have burned up transmission with Superchip but I always reset to towsafe prior to pulling anything.

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.

First off, love the truck, got mine with only 75k, pretty much bone stock, and I'm now at 128k. I've ran through most of the standard maintenance items (fluids changed, brakes replaced ect.), and the truck has been entirely dependable through it all. I have no fear of getting stranded as it has always got me where I need to go. Interior is decent, lots of cheap plastic but I get that its an early 00's vehicle and that was common. I dig the looks, just put 33's plus a level kit and it looks/drives great. The 2 things I don't like. Fuel economy is terrible, like 11.5 if I'm being tender footed. Second, with that terrible fuel economy they only give you a 25 gallon tank. So nothing big in terms of how bad things could be, but there's my 2 cents.

This truck was without question the nicest riding, looking and driving truck I have ever owned. Good power for towing or snow plowing with the standard 6.0 gas engine. This truck, despite its terrible fuel economy [avg 10 mpg with 4.10 axles] was always a pleasure to drive. Two days ago I started up the truck to hook up the job trailer it was hard to pull out of park. I noticed the check engine light on and noticed rough running along with a burning smell. I had it towed to the dealer and got a phone call that mice had eaten wiring in the power center under the hood and that all the wiring and the power center would need to be replaced. After seeing in person what a catastrophe it must go.

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, it's 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!

Looked a long time for a new truck and this one was the best. The Dodge MegaCab has a larger interior but the GMC has nicer creature comforts. Tremendous acceleration and quiet ride. I got the rear seat entertainment package with the DVD and the kids are having a great time.

I highly recommend this version of the GMC to those who do not mind a stiff ride that will pull anything a truck is supposed to pull. The 6.0 engine coupled with the 4.10 rearends give it enough power to pull a house off of it's foundation if you wanted to put it to that type of test. I put it to the test using the 4X4 at Ft. Fisher, NC in sand that others were getting stuck up in and had no problems once I dropped the air pressure down to 20 lbs per tire from the origional 60. The fishing was great also. I've had 9 other 4X4's, between Ford and Chevy's and this GMC is by far the

I finally brought my dream truck 2 months ago. Its a GMC 2500 Duramax diesel. Its fun to drive and I like to show it off. It never knows when to quit or never even knows the word. I like the appearance it has it not all chop up it not slanted back in the front end. It a tough truck! I like the 4 doors. Also it has alot of room and looks great. Nothing even compares to it.

WOW....What a fantastic Truck! I have a 1995 FORD 250 Gas (70K Miles), and a 1994 GMC Gas (113K Miles). The 2005 GMC is comfortable enough and even with the longbed easy enough to drive and park that I leave the car in the garage and use the truck for work and play. When it comes to the work portion it is one powerful, competent truck. I wish the side mirrors were the size of Fords. All the manufacturers need to install a tie down hook in the front middle of the truck bed. Metal around rear wheels in truck bed is too thin in the GMC. GMC needs a radio mute button on the steering wheel. Needs additional LARGE cup holder for the driver in center consol. Cup holders too close together.

I have owned 7 GMC/Chevy Trucks over the last 25 years. This truck measures up to the others very well. The only real complaint I have about it is the fact that that it is very light in the rear end. I am a disabled veteran and need to be able to move around in the cab quite a bit in order to stay comfortable and find that this truck gives me the freedom to do so very easily. Riding in friends trucks has shown me that I certainly made the correct decision when I chose this vehicle.

This is by far, one of the best, if not the best truck I've 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 showing 22 to 23 mpg on highway. Very smooth shifting with Allison transmission (even under load). Ride is a little stiff, but expected with 2500HD. Truck is extremely capable.

This is my first GMC truck and so far I'm pretty happy with it. I have to say though I got what I expected from a 3/4 ton truck. Pulls the loaded dump trailer with ease. Fuel economy is rather dismal but it is a full size pick up with a 6.0L V8 so what can you expect. My power steering pump "whines" which the dealer tell's me that its just the way a 2500HD is. That is the one thing that bothers me the most about the truck.

Bought it new last month. I had a problem with the overflow tank leaking into the wiring harness and ruining a control module. 10 days in the shop and then the radio had to be replaced. Some gremlins in the electronics. If it is all fixed this will be my dream truck! I have the diesel. I am getting about 17mpg at 70-75 on the highway vs 14 for my 2002 Chevy K1500 w/ the 5.3 ltr. This thing will go straight up mountains without downshifting! What a beast! I was towing about 9k lbs behind the Chevy. I can't wait to hook "Max" up to the trailer! XM is nice for trips too. I have the buckets in front and the console encroaches on my leg when driving (I'm 6'4"), but you get used to it!

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.
