What is the best way to determine what manufacturer makes America's most durable, dependable, toughest truck?  What do you think?

After watching the newest episode of "Top Gear", where the guys test three trucks to come up with "America's Toughest Truck".  I am looking to my fellow truck nuts to help me answer this question.  What would be the best way to test for the most dependable, durable, toughest, American made truck?
