Since ‘local’ playground is boring, using a vehicle as mobile base is much more convenient.
So, all floor trunks, 1 fridge, 1 bed, 1 kitchen, 1 welding rig, 1 recharge station and all of this is nicely sorted. One for ammunition, one for weapons, one for spare parts, 2 or 3 for vehicle parts, and so on.
Mostly only the stuff really needed, but I like it sorted.
