Nomadic agricultural groups
Agricultural nomadic groups travel to abandoned villages. Inside the ruins they search for useful materials they can recycle. They live in cargo trailer houses, often converted shipping containers.
The automated CLT (Container Load Trailer) transport system is an old military technology used to transport trailers with military equipment on rough terrain. The CLT system clamps the trailer and is equipped with self-driving technology.
