The facts are what they are. There are more domestic trucks sold than import ones, domestic vehicles use more domestic parts and labor than import ones, and domestic manufacturers employ more US workers and keep more money on our own soil. Believing otherwise is a matter of being uninformed.
In terms of quality, the Big 3 have been building trucks for 100 years, they know what they are doing. Personally, I think its yet to be proven if the import companies can do the same over the course of time. I suspect they can to some extent, although their trucks seem more like passenger cars than actual trucks to me. Either way, there will be people who like their features and people who buy into their hype, but that doesnt mean the domestics arent making excellent trucks too.
