I like that enormous cargo wagon! I may have to add it to my supply of post apocalyptic vehicles.
I made a cart for the Arab and donkey, inspired by the image Story posted. The cart is mostly scratchbuilt, with the bottom made from leftover ABS raft material from my filament printer. It's usually waste, but I save all the ABS. The sides are Plastruct ladders and the suspension is scratch. The axle supports are from an RPM FT-17 kit:
I'm building an old Zvezda/Italeri Zil-151 and while I'm thinking about color and adding the last bits, I used it as a platform:
It's not a very big vehicle. The tires are from an old RPM BA-20 kit and the rims/wheels are yet more M113 wheels trimmed to fit:
I may just have the guy riding the donkey to give more space on the cart. I need to add some more bits, including making the yoke and harness.
