Duramax

I think it is a very good truck. But I can tell you I think a tin can has more thickness than the sheet metal used on this truck from past years. It is so thin I am amazed it is holding. I also noticed a lot of the quality is gone everything is cheaply built and poorly attached. Other than that the duramax and allison combination is by far better than Ford and Dodge.

This car is simply amazing in every single regard. Just looking at it with its chrome and black paint give me butterflies. Everything's Perfect: Exceptional Ride Quality, Excellent handling, sharp and handsome interior, macho exterior, insane towing capacities, almost unheard of amounts of torque, heated and cooled seats,-I could go on all day. This vehicle is also a charm off-road, capable of passing going through anything although Front, Center, and Rear locking differentials would help contribute to its off-roading prowess. Towing is also done in comfort and ease as the engine does not even begin to strain even under the heaviest loads. I would not think twice about buying another one.

Was missing my truck and the GMC 2500HD was the fit for what was ailing me.I looked at fords dodges and toyotas and the GMC just looked and felt like it meant business. Ride is good for a HD and the acceleration is great.I seam to be able to achieve approx 18-20 mpg with mixed driving,However this goes down quick when you feel the need to drive spirited.Seats are plenty big enough for 6 foot tall 260pnd man.Sits up higher than most in class and on a wt comes with quite a good bunch of features,XM,Onstar PWR,WIN,LOCK. Mine has heavy duty everything and is pretty much a rolling mountain of solid steel.

A Disgrace

2011 GMC Sierra 2500HD SLE 2dr Regular Cab 4WD LB (6.0L 8cyl 6A)
4 of 5 people found this review helpful

This is a diesel, always garaged w/69K miles. Also washed routinely including winter,superior maintainence. The list of repairs goes on forever: computer reflashes, glow plugs, fuel injectors, throttle body, steering column, all parts of the diesel exhaust system. It needs a new air conditioning compressor, and now the ultimate insult - rust above both rear wheel wells. Body panel rust problems went out in 1977 when manufacturers went to galvinized body panels. GM is so incompetent they don't put decent rust proofing on their trucks (serious rust also under the hood on the hood latch). Big mistake buying this truck, poorly engineered,QC and manufacturing below par. Tells you what GM thinks of its customers

Great Truck

Have my new 2500HD 4W for a month now and very pleased. Overall truck is superb and beats the heck out of my older Dodge. Pulls my boat like it's not there. Ride is good and mileage is running avg of 17 mpg. I got the split buckets with console and love it. Ditto the comment that tires could be a bit larger. Really very happy with the purchase.

15 months later, still a great truck

2008 GMC Sierra 2500HD SLE1 4dr Extended Cab 4WD SB (6.0L 8cyl 6A)

This is definitely a Cowboy Cadillac. Performance wise, the gas V8 has all the power you'd need and tows my 7K # trailer with ease. The tranny shifts smooth but as another reviewer said, make sure you get the TCM flash for better kickdown response. The 2500HD 'pure pick up' interior on the SLE not only looks great, it's durable and functional as well. The front seats are great for long road trips. I'm getting about 12 mpg around town and up to 17.5 mpg highway at speeds up to 65. Above that, it nosedives into the 12-14 range. Overall, I'm completely happy with my truck after 15 months. I've had no problems and plan to keep this for a long time.

Best truck I have seen, tested all

I use to own a 2008 Dodge ram 1500 5.7 hemi, and put 40,000 miles on it in less than 2 years. Fairly happy with that truck, and I have not encounter not even one single issue. Looking for more power, and better style, more options/better comfort/better quality, so I've tested all of them out there. The only one which satisfied my demands was the gms based on manufacture options that was installed like on board info system, back-up camera and sensors, on star system, teptronic 6 speed, auto-lights, shift turn-signal on the mirrors and more cabin space. So far after 9 months I'm very very satisfied with the quality and performance. I highly recommend to anyone this brand name gmc.

Duramax/Allison combo is a beast!

This vehicle was a replacement for a 2005 2500HD Duramax SLE and the engines are nothing alike. The new Duramax and six speed Allison is quieter, smoother and the towing power is incredible. We are towing a 35 foot travel trailer and it is like there's nothing behind you. The Z71 package does increase the stiffness but the ride is excellent. The interior rivals my '07 Denali. If you gotta tow, this is the one to buy.

Sharp comfortable work truck

I am just approaching its first 1000 miles, so 13.8 ave. mpg of the 6.0L gas engine in wet to snowy suburban/hwy driving may improve in milder/dry weather as it gets broken in. The SLE1 interior trim is a step up from your average work truck with comfortable seats and leather wrapped steering wheel. A smooth quiet ride for a heavy duty truck under most conditions. Feels heavy, but stable and turns on a dime when you want it to. The 26 gal tank may seem limiting, but that is still good for mid-300 mile range, farther than most people would drive without taking a break. Overall it would be hard to find a better truck.
