I traded in my 02 Dodge about 1500 miles ago and I could not be happier. The truck performs great and will haul the snowmobile trailer much better than the Ram did. I am averaging roughly 15mpg which is 3mpg better than the Dodge.

I traded my 2001 GMC 1/2 ton 2WD with 195K miles (it still was strong as heck)for this truck and love it. I have always had good luck and good service from GM trucks. I bought this one with only 25K miles on it. The 8cyl to 4cyl fuel management was a little awkward at first but it is systematic now. On the open interstate at 75mph I have averaged 18mpg+. I was surprised. I have towed a 27ft camper with it with ease. The seating is comfortable even on long drives. Two thumbs up !

To JUNK!!!! Too many problems with check engine light coming on constantly. For some reason, the gas cap constantly comes loose. GM should provide better stock tires. Had a flat from a piece of limestone gravel. Dealer told me I should drive on better roads! (It's a truck, isn't it?) Should have stayed with Ford. Big mistake to buy this truck. Dealer isn't interested in helping very often. It takes multiple visits to fix one problem. Maybe if the service manager got off his lazy [violative content deleted] of his chair, it could be fixed. Last GM product EVER!

Gas mleage is remarkable for a large truck with the 5.3 l engine. I typically average 18.9 combined driving and 20.2 on long interstate trips and have measured it numerous times. I test drove all the trucks on the market and this is hands down he best on the market. The quietness, comfort, handling, audio system is just simply the best on the market.

I test drove every make of truck and this one got my money. Sharp truck and a real headturner with my Black Z-71. Power is great and off road ability is only topped by a Wrangler (I'm an avid Jeeper). Can't say enough about the ride comfort and quiet demeanor, very nice interior. I was looking for a truck, not a Prius or Cadillac. This is the perfect truck.
