Please Ken, I don't think that anyone is going to argue that the KDC-10's that were bought over 24 years ago second hand from an airline are "better" than the MRTT or KC-46 that are still fresh from the factory.
I never said nor remotely suggested that anyone was going to argue that the KDC-10's "are better than the MRTT or KC-46". Indeed I stated the opposite.
....no need to bash the KDC-10....
I would never dream of bashing the KDC-10. I worked for Douglas back in the day and was part of the KC-10 program as well as the program to mod the Martinair DC-10s into KDC-10s. And as an aside, the KDC-10 was the first tanker ever to use a remote aerial refueling operator (RARO) station with a 3D camera system. The KC-10 used an aerial refueling operator station with a huge window in the belly, the world's largest pressurized window.
