The limit on the MLG is about ground pressure. There is a reason for that bigger frames are adding additional MLG. Thank you, Mjoelnir ! That's a serious hurdle but I think it's still too early to say Boeing cannot find a way of designing a competitive 778-based freighter in the future. Adding a center MLG would do it, opening the way for a serious MTOW increase.

The freighter is just not needed now. Just the optional configuration provisions in the basic 777X. Boeing has the 747 F. As long as it is available, plus plenty of used 777-300ER ready for conversion, no one will need the X freighter yet.

The best that can be said about the 748F is that it is a capable but niche aircraft, with an uncertain future. The 777 F is Boeing's best trump in the freighter market, whereas the prospects of a 77W freighter conversion are hazy. There is presently no freighter conversion programme, the main reason being that the need for floor reinforcement would make the conversion extremely costly.

True is, there is HUGE quantity of 777-300ER aproaching the moment of possible conversion. As always: "we will see"

There are two sort of freighters - mixed "heavy" freight and big volume light freight.....
But who knows.
There were similar doubts about 737-800 and look now - it seems that the conversions are being done in volume.

If I'd be Amazon I'd get dozens of old Emirates 777-300ER for conversion and a second and possibly third lease term.

There were similar doubts about 737-800 and look now - it seems that the conversions are being done in volume. There has been a lot of talk about 777 P2F freighter conversions. Up to now nobody started it. The Problem and main cost would be the exchange of the complete main floor structure. The beams used in the passenger 777, do not carry the weight needed for cargo. The new build 777F have a completely different floor structure and material compared to the 777 pax frames.

There is no 77W conversion programme because the cost would be very high, whereas potential operators need a low-cost product. The situation might change in the future, when 77W acquisition prices get very low, though the conversion costs will remain high.

Express cargo is lighter weight than general air cargo. This is why some P2F for Amazon might work without to many changes.
