It is certainly possible that Ford will leverage technology between models but as someone who owns a fleet of these trucks I can tell you that the “platform” is not nearly as unified as you might think it is across model numbers.

Cosmetic details such as in the interior or the cab are shared between models but when it comes to the frame, drive train, suspension, etc. (The things that really matter when you buy a truck.) the models are completely different. Below the surface an F150 has little in common with the F650 or even an F450
