According to cars.com, the 2010 Dodge Ram Trucks are "Most American" in build content.
Ford & Chevrolet are not even in the top 10. It seems Ford only has 55% build content.
So much for the American built Ford aurgument, it may be assembled here, but not with American supplied parts.
Ford held the highest B/C for years. Its easy to be number one when you are the cheapest truck built.
