Sharp comfortable work truck

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

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.
I am a Diesel guy!!

If you are looking for a tough, dependable truck with a long life expectancy, this is what you are looking for.......... Let's start with the only negative. This truck is a two wheel drive and it does create some issues. If you hookup a trailer, you can get stuck on level ground in the grass, if it is wet. I am running high quality street tires, and they are great tires, but the low end torque is so good that it is difficult to get it moving on a wet, non-paved surface. Once it is moving, you are good. I am running a Bully Dog BDX programmer. It doesn't provide as much HP as my Triple Dog in my 2004 truck, but it still has plenty of get up and go. I have triple gauges on my pillow. With the BDX, I run a consent 5 psi of boost at cruising speeds, but when you need to go, it drops a gear and JUMPS to 30 to 35 psi. It's NOT an "out of the hole" dragster, but it will perform when you need it too. SLT package means all the creature comforts, and they are accommodating. They ride is firm to say the least, and it can be rough depending on the condition of the road. I have a rear air brag suspension (after-market), and it's probably time for new shocks. And there is the typical GM issues, cracks in the dash from the sun,etc. I am averaging 18mpg with the BDX chip. I can get that up to around 24mpg for just highway driving. I have added an auxillary full tank in the bed of the truck that let's me go about 1200 miles between fill ups, which is about 71 gallons of fuel between both tanks. And finally safety. I am weighing in around 7300lbs, which puts me at double the weight of most vehicles on the road today. Law of physics are on my side with regards to accidents.

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.
Happy I switched to diesel

I traded in a 2004 F150 4.6L with 25,000 miles to get a 2008 GMC 2500 6.6L diesel. The performance is unreal. I am getting over 13 mpg, which is the same as the 150 on Premium and I get 3 times the power. The ride, fit and finish are as good or better and the information center is a real boon. The shakedown will continue for another six months but for the first 30 days I could not be more pleased.
A Decent Truck With a Poor Drivetrain

This is a decent truck, but NOT with the 6.0 and GM 6 speed. You HAVE to get the Duramax if you need a 3/4 ton truck. The gas motor with fly by wire throttle, and GM 6 speed, is a horrible combination. It is a death trap when trying to merge with traffic, especially in conditions when you are on and off the throttle. There is up to a 3-4 second lag where absolutely no throttle input is given to the engine, no matter how hard you press on the accelerator. I believe GM implemented this so their tranny wouldn't explode. The engine and tranny computer work together, and the tranny computer tells the engine computer to not give any throttle until the tranny is ready (it never is).
Well-built truck

I recently purchased a 2010 2500hd 6l gas truck with 6 speed tranny, i am very pleased with the towing and ride quality of the truck, it pulls the 7000 pound trailer with ease, i would recommend this truck for anyone looking for a cheaper alternative rather than diesel.it has 200 km but i am sure fueld milage will improve, currently said 14 mpg highway towing 10 mpg, but not broke in yet.
Great Truck

This my first 3/4 ton truck. Now have 9000 miles on the clock. I have owned about ten 1/2 ton trucks over the last 40 years. I have owned mostly Ford trucks. GMC has really done well with this truck. It is the 6.0 gasser. I haul a travel trailer and perform routine around the house hauling. The powertrain and load performance difference between the GMC 1500 5.3 and 2500HD is huge. I get better gas mileage pulling a trailer with this truck vs. my 2008 GM 1500 5.3 gasser. I have been getting 17mpg on the highway without a load. 11 mpg pulling a 7000lb trailer on the highway. I believe the GM HD trucks are the way to go with either 6.0 gasser or the Duramax / Allison combination.

First off, after researching diesel trucks for over a year, it was clear that the Duramax/Allison power train was the "gold standard". I recently installed a Banks air intake, programmer, and exhaust system ($2500) and the performance is startling. Stock, average fuel economy was 16.2 (70 mph+ freeway); I hope the Banks package increases that up to 2 mpg. I stopped to watch a local, weeknight rodeo event in Paso Robles, CA and there were eventually 40+ trucks with 20-30' trailers, all diesels: 1 Chev, 3 Fords, the rest GMCs.

I owned an early 2001 HD 2500 with an 8.1/Allison. While solid, fuel consumption, oil use, and piston slap made ownership less than desirable. After several years of Toyota and Nissan ownership, I ordered a 2011 GMC Duramax SLT Crew. The 2001 and 2011 are similar in ride and appearance, but power from the 2011 is considerably greater. The Duramax is quiet and interior noise is low. It has impressive electronics, and fit and finish appear excellent. Interior is nice but lacks appointments. Other than the large center console, there is limited storage for small items such as sunglasses. The exterior lacks tie downs and storage. This is my sixth GMC and first one in ten years. I'm back!

I previously owned a 1999 Silverado 1500 4X4 Extended Cab Standard Bed and a 2007 Sierra 1500 4X4 Extended Cab Standard Bed I wanted to upgrade to something more powerful with more room. While I really don't need it for towing at this point, I can only imagine how great of a towing vehicle this will be. I am very impressed with the power of the Duramax diesel, as well as how quiet it is compared to the Ford Power Stroke and the Cummins in the Dodge. I test drove all 3 brands, and what won me over was the performance and power of the Duramax, as well as how much smoother the Allison Tranny shifted over the transmissions in the Dodge and Ford. The interior is the best of the 3.
