Bought my 2500HD 4x4 back in August. 8500 miles later, I still love the performance, comfort, and looks of it. I've made one 900+ mile trip towing a 4,000 lb. trailer, and it drove like there was nothing attached to it. The interior comfort is excellent. The seats are very comfy, and the quality is outstanding. I have not had any problems to speak of. I'm real impressed with this truck. The only downside is the gas mileage (to be expected). I average 12/13 in the city, 16-18 highway (depending on speed) and 12.5 towing a trailer on the interstate. Reckon the 6-speed auto helps the MPG a bit.

A Decent Truck With a Poor Drivetrain

This is a decent truck, but NOT with the 6.0 and GM 6 speed. You HAVE to get the Duramax if you need a 3/4 ton truck. The gas motor with fly by wire throttle, and GM 6 speed, is a horrible combination. It is a death trap when trying to merge with traffic, especially in conditions when you are on and off the throttle. There is up to a 3-4 second lag where absolutely no throttle input is given to the engine, no matter how hard you press on the accelerator. I believe GM implemented this so their tranny wouldn't explode. The engine and tranny computer work together, and the tranny computer tells the engine computer to not give any throttle until the tranny is ready (it never is).
Happy I switched to diesel

I traded in a 2004 F150 4.6L with 25,000 miles to get a 2008 GMC 2500 6.6L diesel. The performance is unreal. I am getting over 13 mpg, which is the same as the 150 on Premium and I get 3 times the power. The ride, fit and finish are as good or better and the information center is a real boon. The shakedown will continue for another six months but for the first 30 days I could not be more pleased.

First off, after researching diesel trucks for over a year, it was clear that the Duramax/Allison power train was the "gold standard". I recently installed a Banks air intake, programmer, and exhaust system ($2500) and the performance is startling. Stock, average fuel economy was 16.2 (70 mph+ freeway); I hope the Banks package increases that up to 2 mpg. I stopped to watch a local, weeknight rodeo event in Paso Robles, CA and there were eventually 40+ trucks with 20-30' trailers, all diesels: 1 Chev, 3 Fords, the rest GMCs.
