The above photo is the Fokker60 in the real world, it floor 1.2m height.
Which shows the is pallet is not the one that gets loaded by a pallet loader like the one that comes with GSX, which are called ULD, and those are what I was referring to when I've said "the GSX manual has a list of all airplanes that use pallet loaders in real life", there's a complete description about what ULDs are and which airplanes use them.
ULDs are the only kind of pallet supported by GSX, and ULD are loaded with that kind of vehicle which can't reach such low doors, and it has been modeled exactly like the real one (FMC Commander 15), and can go as low as 1,92 mt (not 2.2), and this is 100% realistic:

And, you can see in this video they use BELT LOADERS to load cargo on a cargo-converted Fokker 50:
