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.
Duramax/Allison combo is a beast!

This vehicle was a replacement for a 2005 2500HD Duramax SLE and the engines are nothing alike. The new Duramax and six speed Allison is quieter, smoother and the towing power is incredible. We are towing a 35 foot travel trailer and it is like there's nothing behind you. The Z71 package does increase the stiffness but the ride is excellent. The interior rivals my '07 Denali. If you gotta tow, this is the one to buy.
15 months later, still a great truck

This is definitely a Cowboy Cadillac. Performance wise, the gas V8 has all the power you'd need and tows my 7K # trailer with ease. The tranny shifts smooth but as another reviewer said, make sure you get the TCM flash for better kickdown response. The 2500HD 'pure pick up' interior on the SLE not only looks great, it's durable and functional as well. The front seats are great for long road trips. I'm getting about 12 mpg around town and up to 17.5 mpg highway at speeds up to 65. Above that, it nosedives into the 12-14 range. Overall, I'm completely happy with my truck after 15 months. I've had no problems and plan to keep this for a long time.
Sharp comfortable work truck

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 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.
