Fiat builds these for 7 or 8 companies globally as far as I know. All are built with the basic chassis and design changes are implemented regionally and per manufacturer specifications. If Dodge chooses a crappy power train to market to North American buyers, that’s too bad. The diesel version with standard transmission is even used here widely as cargo vans for supermarkets and the majority of our ambulances. The ambulances are usually Peugeot branded though.
The Ford Ranger here is a rugged and reliable 4x4’s and has been for years. In the US it’d be hard to find anyone that say a Ford Ranger is a reliable everyday use work vehicle. Again, we get a Ranger with a turbo diesel and a manual tranny. Turn the key and roll. They just built different.
