Understanding only a little about how cargo containers are used, I would assume they are filled by volume rather than weight ( except in the cases of extremely heaving materiel, like iridium ingots or something) . So unless all of the cargo containers are of equal weight, you might have an issue with weight distribution without some smart software to figure that out. I'm assuming that wouldn't be too difficult for a company that designs planes, rockets, and space ships. But I guess that would have to be considered at least. I might not be able to send certain combinations of cargo containers, which might be an issue for my horse feather and iridium Ingot company.
