Very Powerful. Very Comfortable

I have been driving my truck for about a year & a half. I was excited at first because it was new. Now I am still excited! The Duramax/Allison is a just a great design. There is so much power for towing. This truck should come with a warning light reminding you that a trailer is attached because you will forget that it's there! No more "white knuckle" driving while towing, built in brake controller works really well. This is just flat out awesome! The seats are like flying 1st class, interior is much improved. SLT has all the goodies, more like a luxury car, except it's a truck. Why have a car anymore?

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.

The Best I've Seen

I have put 70,000 miles on this truck, and it is by far one of the best vehicles I have ever owned. Any negatives I have seen on here were in reference to the SLE interiors or the Gas Engine and its transmission. The truck handles very well and can pull anything you can imagine. The 6.6L Diesel and its transmission get excellent mileage for a truck this size. I get 22mpg on a 55mph highway and 19mpg on 70mph highway. City mileage is around 14mpg(with lots of stoplights). I don't think you could find a quieter diesel thats more comfortable, more powerful, and tougher than this truck. The seats do have good lumbar support in the SLT package. I really highly recommend this truck.

I love this truck so much! more quiet then a Dodge or Ford Diesel. This truck could pull a battleship with it's strong Allison transmission!

In "07 I needed a truck to tow a 7000lb 14x9x9 box trailer in western PA. I test drove 'em all and fell in love with a Ford until I learned GM had the most torque, hp & mpg. Found a GMC L82 with all towing packages. I tow 5 days a week and avg 9.5mpg city and 15 on the hwy at 62mph or 2k rpm, above 65 mph the aero drag zaps the mileage to 10.5. The PA hills takes another mpg. Without my trailer I get 15 city and 21.5 hwy. I love the performance and the bucket style seats, it feels like a Camaro on steroids. Get compliments every where I go and with 30K miles I've been everywhere.
