A fully functional rotator, with outriggers, and lights? Sure, that could be 100% functional, but it will take really deep pockets, or some creative ingenuity. Hydraulics would be an easier, but a more expensive route to take. Electronic linear actuators, miniature gear motors with cable, chain drives, or screw drives might be a more affordable path, but it would take a little more engineering. Both would give good results. How scale do you want it to be? The good thing is it looks like a lot of the mechanisms used would be easy to hide inside the boom, or wrecker body.
