Correct me if I am wrong the difference between 777-300ER and 777-300 is additional fuel tanks and an uprated engine = extra range...

I think the wing, too.
Thus the bigger wing to carry more weight, bigger engine for the same (is there any change in landing gear?) - those distinguish -300ER from -300 and -200LR from -200ER.
One wonders how the Boeing 747-800 is to be competitive with 777-300ER?
Or perhaps it is not... no one wants Intercontinental, months after "launch".
Anyway, Boeing tried, and failed, to design a 747 trijet after DC-10 and Tristar turned out to be in some respect cheaper to fly than 747. The upper deck bump disturbed airflow into the inlet, so they had to keep 4 engines on the SP. How exactly does the fuel burn of SP compare with DC-10?
Since 747-800 does not extend the upper deck all the way to tail, centre engine is out of question. Or perhaps it would be better to fly 747 as a twinjet, like 777? The engines seem almost big enough...
