"other than the injector problems witht the LB7 (GM covered upto 200,000mi) its a great fuel effient full size truck with style, i get 24mpg on mine! thats awesome for a 6.6, it gets the same fuel mileage as most imports BUT when i need to haul or pull something i got the extra power. i know have 270,000mi on my wonderul truck and still looks almost as good as it did when it came off the showroom floor, ive replaced the fuel injector pump and the transfer case, GM replaced the injectors"
"This is an excellent truck. Have owned for 3 yrs, bought used and have never had an issue with it. It has never been in the shopr for other than routine maintenence and has never let me down. Will pull anything I have hooked up to it. I have a 5th wheel TT that wieghs in at 12,000 lbs and it pulls it without hesitation."
"I bought my truck new in 2003 and i still have it today. I would not trade it for the world. I pull a 30ft livestock trailer 275 days out of the year. I have replaced the water pump and the batteries. The truck has over 365,000 miles. It has tons of power. The automatic allison tranny is ultra smooth. The truck is still running as good as it did in 03. Sorry it's not for sale."
"This is my third truck I have owned. First Truck was a Dodge and only kept it for a year because it wsa falling apart. Second Truck was a Silverado 1/2 ton. Great truck. Now I got a 3/4 ton with the Duramax. By far blows every other truck out of the water. Great power for towing. Very reliable. I have had it for 3 years now and at 76000 miles no probelms."
