My first 3/4 Ton Truck & Diesel

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.

I bought my 08 SLT, Diesel on New Year's eve day, 08. I have put on 17,000 miles mixed mostly highway and suburban with a good bit of weekend warrior hunting and camping trips. I commute in this baby and my combined mileage is 15.7 over the last 9 months. That's with a cap on the back,and with 35 miles a day in hardcore SF Bay Area highway traffic hell. I don't tow but it will haul a back end load of hunting equipment, dogs and coolers full of meat. Honestly, I could use a lesser truck for most of what I do, but when I need to step up this truck takes it and keeps going. I can stick 3 dogs in the back of the cab, w. seats folded and they ride in comfort and one of them clocks in at 120lbs

I have owned 6-7 GM products over the last 25 years and I can honestly say that the appointments and driving ability of this vehicle are outstanding. Everything is perfect

9.5 mpg city 10.7 highway. Door handle under armrest is a pain to get to. 5.3 engine would give enough power as I run empty 95% of time Needed 2500 to plow snow. Needs cup holders in dash.

body moulding falling off

My 2008 GMC diesel pickup has 41.000 miles and has been a good truck. However it will be 5 years old in December, and the body moulding on each side is loose and starting to fall off. The dealer said it is a common problem, but since it is out of warranty they would not fix it. I went to a body shop, and the person there said it is a common problem with that body style. He said a solution is to remove the moulding and glue and buff out the paint. His estimate was $240.00. I'm disgusted that this problem should occur on a $40,000 vehicle. I see 25 year old cars and trucks with the body moulding still intact. I'm disappointed GMC won't take care of the problem.

This is a great truck,This truck was used in the oil and gas industry and it has over 188,000 miles that I put on it.The truck has never been put in the shop for any major repairs.just regular service.Avarage 4000 to 5000 miles a month and it never left me on the side of the road.Tows like a beast! Used to pull loads of 7 to 9 thousand pounds over 600 miles @ 70 MPH.In fact I liked the truck so much when we got our new 2011 GMCs I bought this one from the owner.now she is retired but I would'nt hesitate to drive the truck anywhere.

Before buying this truck I owned a F250 V10. This truck was supposed to have 50 more hp and comparable torque but its lack of power is remarkable. My mpg is ok until I hook something behind it then its 5mpg... I have had no less than 20 warranty claims in 1 year. It absolutly can not handle any hitch weight without bottoming out. The sheet metal used to form the body is so thin the smallest bump and you have a dent. I really had high hopes that GM had a great truck but after the trans went out @ 6500 miles and many many other issues I'll admit I was wrong.. This pickup is fine for pulling your boat or cruising around but if you want a HD pickup do not buy this one.

08 single cab work horse 2500hd

I really can't say anything bad about my 08 single cab 2500 HD GMC Sierra. Reason being is bc I've owned it since brand new, the price was more than reasonable and when I test drove it for the first time it really felt like a truck. Its 6.0 gas with torsion bar front suspension so alittle ruff ride but all good bc its tuff and a ton of power out the whole and beyond. Its ten years later now and I still drive it every day for work and pleasure. Through the years I've put bigger tire,rims,tinted the windows,added stereo and leveled the front end. In ten years I've only had to replace one hub bearing other than I've just changed oil regularly,air filter ,3 batteries and 3 sets of tires and she just keeps going with 185.000miles. Also I've never changed brake pads witch blows my mind with all the towing I do. So to anyone that is thinking about purchasing this particular type of truck as long as it looks in decent shape I would highly recommend it.

This is my second GMC HD truck, and the imrpovements are too many to mention. This is by far, the best looking truck on the road. I'm averaging around 15 mpg around town and recently got 19 mpg on the highway going 85 with 2800lbs in the bed. GMC builds the best looking, most reliable, most fun to drive pick up trucks on the road.

It Seems Like a Keeper

I just bought a 2009 GM 2500 with the Duramax/Allison combo. Been with Ford all my driving life. So far, a great truck. Excellent power, very quiet and greater than 20 mpg on highway when unloaded. Seems tightly made. 2008 F250 previously; a great truck but physically too large for my needs. GMC offers similar towing performance, better mileage so far and a better ride in a physically smaller package-- with diesel power. Overall, I think the GMC offering is the top overall in the 2500/250 line for daily use/driving. I was not impressed with Dodge quality; my Ford was great but meant for wide open, all day towing. GMC offered the best package with the fewest comprimises. Very happy so far.
