"I have had this truck for 3 yrs now. It has pulled everything from 5th wheels to other trucks out of the mud. This truck is everything i hoped for when i bought it. 18mpg, 11 while towing. The duramax and allison combo works like no ford or dodge would dream. great power and comfortable on long drives. I won't plan on ever selling it. Think it is a little pricey for most people like myself, but it has proven to be one awesome truck"
"I've owned quite a few vehicles through the years...this has to be the best one ever. You are inside and hear nothing from the outside. Going down the road not a creak or rattle to be heard. And talk about power...I have the Denali with 403 hp...no passing problems here. MPG is not that great, but I have been told by others I seem to have a "lead foot"...."
"I can't say enough great things about this truck. I would buy it all over again. You will not be disappointed. I tow the camper and don't even know it is there. I can put my 700 ATV in the bed with a little room left. Handles great and is very comfortable."
Pros: "Good mileage and power and pick up for a truck"
Cons: "poor door design, hate automatic door locks"
Likely to recommend this car? (1-10): 6
"I own a 2008 SierraK1500 Crew 4WD with 95K miles on it now looking to trade it in so will find out what I can get for it now. Been a great truck, I live in the high country and own a ranch so it has to do several jobs, its worthless to haul even the lightest trailer. Does not feel good as any trailer pushes it around, and then when I put horses in it no way. This truck has been very reliable, just got new rear brakes/drums at about 85K miles; I average about 16 mph in summer here in the mountains and have gotten 22-23 highway, never use the E85, that brought my mileage down worthless fuel if you ask me. The driver side door sagged right off the bat, now it creaks when open, the locking mechanism has a mind of its own and locks immediately upon putting it into drive, making it very hard to feed livestock off the back, in the winter, in the snow, plus it locks randomly so you have to have the keys in your pocket when you get out of the vehicle at all times or roll the window down (like I do) makes it a pain at gates etc. 4 wheel drive has worked consistently great. I just changed the rear seals at about 80K. I use Big O tires which are worthless but the first set of tires I had on it lasted 55K with rotating but now lucky to get 20 out of a set of tires. I love this truck. Looking at Ford and a 2013 Sierra K 1500 too. Time to replace."
