Since physics allows towing a trailer, the creation of a powerful "Tractor" (Eighteen-wheeler cab) would make sense. Then it can tow a number of useful trailers behind it, from a mining system, to storage carrier, to a Mad Max war platform.
(I'm not even sure if it will be easy/possible to disconnect and re-connect a truck and trailer! Hope so.)

(You can build one or more trailers for it, too, but the focus is the tractor/cab.)
