I pulled a 2006 Colorado over 75,000 miles and loved it. I'd still have it today except that the cargo area kept shrinking!! (LOL) We're now pulling a 2011 Silverado. Cargo area is fine but the full size chest freezer we take to Alaska for salmon seems to be growing too. Along with the outboard, boat stuff, 12 fish poles, etc, etc, etc.
Just remember that you need 4WD to pull the auto transmission, but setting it up to tow takes holding one switch about 15 seconds to set it up. A great toad.
