People do lots of stuff with containers. you could place them side by side, do whatever structural is required, then cut the walls out of the middle to have a double wide, not that wide inside otherwise, if you plan to do body work on a cab. maybe repairing components like doors or fenders could be done inside one. juyst a side note, they get pretty damp inside if your weather is warm-cold-warm. we had one attached to our mechanics shop, with a door sized opening cut in the side of the shop and the container, and found it rained inside there sometimes due to condensation forming on the cold steel walls and roof. you could spray foam the walls and roof to help but then it becomes a smaller container inside. if you have a humid climate but warm enough to work inside without heat then that changes it I guess.
