Excellent family recreation truck
irideharley,06/29/2009
Was considering the Dodge Cummins for it's tough reputation but couldn't swallow the tight back seat for a growing family. A friend had the Chevy Duramax and I haven't looked back since. The GMC Duramax and 6 speed Allison tranny are incredible. Quiet ride, plenty of room in the back seat, power a plenty to pull the bass boat with a camper on top. With or without a load, city and hgwy driving we still average 18 mpg, and at least temporarily diesel is cheaper than unleaded in my neck of the woods. Absolutely no buyers remorse with this truck. Two thumbs up all around.
