Several variants of the cargo case from the AL-6 Utility Drone are placeable as independent objects. The Medical variants of these objects have an accessible inventory, containing a medkit and some FAKs by default. The non-Medical variants have no accessible inventory - even though their TransportItems config suggests they should have 2 FAKs in them by default, and they have the same MaxLoad of 200.

There's no particular reason why the non-Medical variants shouldn't have an accessible inventory. In fact, I actually can't find the reason why they don't, nothing seems to be different in their config. So...they probably should. They'd be useful little boxes if they could actually contain stuff, and it feels like they were intended to given they have config entries for it.
