I just think that some need to spend a little more time in the medium and heavy duty industry before they start talking about what is or isn't medium duty. I have worked in this industry since I was 16 working after school cleaning dairy tankers and performing oil changes on Peterbilts for a local dairy transport company.
It is very common in this industry for truck makes that also made engines to use their own engines and not sell them to anyone else. MACK was the first to make their own engine in 1938. Today you have PACCAR, Volvo/Mack, Diamler Truck, and Navistar who all make their own engines that are not sold in any other vehicles that they don't manufacture.
It is also very common for engine manufacturers like CAT, Cummins and Detroit Diesel back in the day to sell the same engine to many different truck manufacturers. Basically the same 3406B CAT, Big Cam III Cummins, or Detroit Series 60 that was available in a Peterbilt, was also available in a Kenworth, International, Freightliner, and so on.
There is a big difference between a truck manufacturer and engine manufacturer. Generally a truck manufacturer that makes their own engines will not sell that engine to be put in a competitors chassis while an engine manufacturer will sell their engines to every truck manufacturer. It has been that way for over half a century.
As far as the Cummins in the previous Ford medium duties is concerned, there is a reason why the Powerstroke was not available for so many years and it had more to do with contract obligation than anything else. For a long time, the only engines available in a F-650/750 was a CAT or Cummins. Since Navistar made the Powerstroke and the F650/750 for Ford, Navistar did not let Ford put the Powerstroke in the F-650/750 because that would be a competitor to Navistar's own medium duty truck with their own version of the Powerstroke engine.
When Ford dumped Navistar and started to make the 6.7L they still had another few years on contract for Cummins to make the engines and with Navistar to make the F-650/750 trucks. Once that contract was up with both Navistar and Cummins, then Ford started to make the F-650/750 themselves and started putting their own diesel engine in the truck which allowed them to make more money by not having to purchase the diesels from Cummins. It had nothing to do with one engine being better over the other, and was all due to money like most business decisions are.
