Ponchus Pilot,
Not true. Makes no difference in what the load is made of. Be it people or cargo. MTOW is MTOW. Already spoke with the design boys in Everett and it's already in the works.
As far as all you boys that seem to think any US politician or the US military would ever spend the money to upgrade the tanker fleet outside of the USA is crazy, stupid or retarded. 767 or 7E7 or another US built aircraft is all that really has a chance. They will make it look good for the EU politicains so they don't trade sanction the US, but that is it.
With how the US economy is right now sending jobs overseas would be political suicide. It will never happen. There are very few foreign built aircraft in the US military.
