> I'd like to see an investigation, however, why a perfectly working truck was shipped overseas and left the American market.

There is a massive amount of used cars in the US, and historically a large demand for these types of vehicles in Africa and the Middle East, where import taxes are lax and it's far easier to register a gray market vehicle than it is in the States. Trucks like this can fetch a much greater premium in those areas, and it is profitable for import/export companies to ship them there.
