Moving my cab around the garage

[ChadBice]

I purchased a truck today. It’s a 1972 SWB in need of a lot of work. I want to pull the cab and box off from the chassis so that I can concentrate on one piece at a time. However, my garage is quite small. The box is basically garbage, so I can leave that outside, but the cab is salvageable. I want to be able to move the cab around my garage as needed while I get the chassis ready. What is the best method to make the cab moveable while off the chassis? Any suggestions would be appreciated. Thanks.
