How abut: The truck is just plain ugly.
It looks like a refuse bin. Square back, low opening front.
When I worked in a lime quarry, we used a bin something like that shape to put all the crap and garbage in The a-frame had a bar across the top and the kiln truck picked it up worth its hoist and loaded it on the back, and hauled away the load to the dump.
No-dairy chocolate?
But I suppose it would 'work n long-distance space travel, where dairy would not exist.
