Interesting!
Nopax, yes, most loaders have the drivers position on the RHS although FedEx did have some built with LHD for the A310 due to the proximity of the nacelle to the cargo door.
From Cranfields logical point of view, it makes perfect sense to put the door on the right BUT..... as every other bird has the door on the left, you then have to know is it a BAe built aircraft or Cranfield conversion before you position the GSE. Also, I still have reservations about putting the driver furthest away from the danger area.
Whatever, I wish Cranfield luck although, if TNT do put even some of theirs on the market, I'm not sure that there is that great a market for the size/capacity.
