I'd like to see the source of your "B" numbers please. Especially the ridiculous Cummins 50% figure.
I was always under the impression that the Cummins had a B10 rating of 350K, not B50, which makes it a true medium duty engine. The other diesels IIRC have B10 ratings of about 200K, same as their gas engines. However like others have pointed out, there are many other expensive things that can break on any high mileage truck besides engine internals.
I don't have a reference but the Cummins has a duty cycle of 350K GM 250K and Ford either 200 or 250K.
Cummins attached to an Aisin trans you have medium duty in a light duty truck.
