My homemade platform system in the back of a 200 series can hold six wolf packs.
On the right side I have a wolf pack with recovery gear pushed to the front and the flat pack filled with hygiene supplies.
On the left are two boxes for dry goods. On the deck, I have room for boxes or whatever. One box might hold our "city' clothing when we visit friends while on the road.
The roof has two small Alu Boxes one with bat wing walls and the other with jumper cables, winch extension spare belt , hoses, air filter ,shop towels etc.
Campfire in a Can , Gazelle gazebo and another Alu Box for misc stuff.
All in all, I think the setup is very modular with boxes removed it need be or added.
