I tend to put one on a (non-folding) cart and drag it around with me when I’m working on a vehicle, and mount it on a bike rack when I want to take it somewhere on another vehicle. When I build them into vehicles, I usually put it on the end of 2-3 frames sticking out the back (or front) of the vehicle, and when working, I stand next to it. If the vehicle is large enough I’ll sometimes put it on the edge of the vehicle surrounded by boards. When installing a heavy turbine engine inside an existing vehicle, it’s best to put it in the vehicle as close as possible to where the engine is going but where you can also stand next to both the boom and the destination.
