The 8.1L, Allison Trans, this vehicle is beyond awesome, lousy milage but that is what was expected. Pull or tow anything, fast as hell, acceleration is neck snaping, stable anywhere you take it. So far no problems like my last GMC (ABS pump went out), the dealer is lousy, can't trust a thing they say. Time will tell.

Drove this GMC across the country, many mountain roads and off highway. One of the most fun vehicles I have driven and I absolutely love the Turbodiesel and Allison transmission combination. I have had zero problems with this truck, you would think it was made in Japan for the quality.
