The fun part is where we get into fluff that X cargo dropper has one or two CargoMechs set up to offload cargo when it lands . . . and by description goes immediately to that job. By description they are a very rough gantry to lock the Indimech in place during travel, hard to imagine its a full up battlemech cubicle.
We also get plenty of fiction bits where cargo droppers are offloading military equipment out in the boonies, but at a 'safe' landing zone. First that comes to mind is By Temptations & By War, a MWDA book by Loren that has one of the local insurgent leaders detailed off to a shift in a CargoMech unloading a Mule or Mammoth that brought in the combat unit's supplies. Instead of meeting with the Cappie commander as originally arranged he gets the detail . . . poor planning on the MAC officer's part b/c he never said where stuff was supposed to be unloaded. Since the insurgents were supposed to be getting some gear that was sent along on the DS for them, and the MAC officer was hostile . . . well the insurgent leader, Evan Kurst- future member of House Ijori, unloaded cargo into his VTOL . . . to include IIRC some BA suits along with munitions and parts.
