When I was drilling, we had a 20 footer for a portable shop. It had swing out hydraulic cylinders on the corners and would lift the can about six feet off the ground where you could self load and unload on a truck or trailer. If you loaded it on the back of a Morooka, you could put a shop about anywhere.
Our front wall was hydraulic fittings, the left wall coming in was a big gas powered welder then shelving with filters and odds and ends. The right side was a big steel workbench with vice, a hydraulic hose crimper then more shelving for parts and safety items.
It was nice to fire up the welder and have lights when working nights.
