Note that the engine and trans are spec'd from CAT and Allison respectively. There's a lot more global manufacturing integration these days, to the point it's difficult to determine country of origin for a product as complex as this due to globally sourced components. Country of final assembly is about the only easy thing to determine.
Being a huge gearhead, I've seen over the past 40 years that auto manufacturers tend to ebb and flow on market appeal, based on the cyclical nature of product development. If they make a misstep when creating a new cycle, it can be disastrous to sales for years to come. Even the best of them occasionally succumb to the short term profitability of coasting on their reputation and brand image alone. Very few manufacturers spend the cash and energy to continually be at the forefront over long periods of time.
What if this whole crusade's a charade?
And behind it all there's a price to be paid
For the blood which we dine
Justified in the name of the holy and the divine…
