Ok, in other forums we have gone round and round about cargo containers. Well this is related. Consider Unit Load Devices and Master Pallets used in Air Cargo. A Master pallet, which is a pallet used in military cargo movement is around 2 by 3 meters and scan support 4.5 tonnes. While Unit Load Devices are generally around 1.5 x 1.5 x up to 3 meters in size (Note there several specifications so YMMV).
On to the 15mm portion of this post, 15mm is generally 1/100th scale for vehicles and the like, thus a quick and dirty Master Pallet is a thin 20 by 30mm base with cargo on top. (Note a 20 by 20 works as well) see attached photos.
Still figuring out how to do ULDs, and related things like ForkBots. And Grav Pallet Jacks.
