Used 2008 GMC Sierra 2500HD Consumer Reviews
This is the 6.6L with the Duramax/Allison combination, not the 6.0L. I previously had an 05' with similar features but wasn't worth the buyout at the end of the lease. There are things I liked about the 05 that the 08 lacks but most of all, I'm very pleased with the truck. Towing is great. Crewcab 8' bed is a long truck though. Park it at home if you intend to go into a city.
This truck is by far the worst riding vehicle i have ever owned. I understand it is a HD, but come on GM, you're not always towing with it 100% of the time. I cannot believe the research and development guys at GM designed it that way. The rear end bounces 60% the time when empty or partially empty. tryed changing shocks and tire pressure adjustment. helped out about 5%. The new 6 speed tranmission in my truck needs work. There is a delay in shifting between 2nd and 3rd gear. This happen 10% to 20% of the time but is annoying.When the delay happens engine racing anywhere from 200 rpm to 1000 before the shift takes place.Tranmission engages harshly when shift happens. Look elsewhere.
I am just approaching its first 1000 miles, so 13.8 ave. mpg of the 6.0L gas engine in wet to snowy suburban/hwy driving may improve in milder/dry weather as it gets broken in. The SLE1 interior trim is a step up from your average work truck with comfortable seats and leather wrapped steering wheel. A smooth quiet ride for a heavy duty truck under most conditions. Feels heavy, but stable and turns on a dime when you want it to. The 26 gal tank may seem limiting, but that is still good for mid-300 mile range, farther than most people would drive without taking a break. Overall it would be hard to find a better truck.
This truck drives awesome! Holds the road great and very powerful (duramax). Current gas mileage is only 15.5-16.7 still breaking in. Truck only has 600 miles. Color is sonoma red.
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.
