As I tell my HD friends often, the buy American arguement is over, Things with American names like Ford, Harley, etc. are no longer totally made here. It is hard to tell what is made here and what is not.
Very true, that Chevy Avalanche featured in the article is made in Silao,(central) Mexico .
The toyota Tacoma is made in Mexico as well. So we have an American truck and Japanese truck both made outside the mother country. Where are Mexican trucks made??

From the Wikipedia article on the Tacoma:
http://en.wikipedia.org/wiki/Toyota_TacomaIn 2010 all Tacoma production will be moved to Toyota's Texas plant in San Antonio. The Tacoma will be built alongside the Tundra, its bigger brother. By doing this, Toyota has moved all of its NA truck production to one plant. This will bring a total 1,000 new jobs to San Antonio.
