I am building recovery vehicles from the AQ steam tank and a recovery vehicle kit from GZG. The recovery vehicle kit is sold by GZG and is said to fit any of their tanks to make them into a recovery vehicle. It has a plow and a crane. The part number is ACC15.
Well I have bought a set from GZG to blatantly copy you as its such a good idea and find. Will use it for my USA forces which should give me the prompt to get them painted or at least add to my paint queue!
Here is the crane mounted. I put it in the travel position, partly so the weight counterbalances the weight of the plow and prevents the vehicle from tipping on its nose. The 'hook' is tilted toward the boiler because it will be tied to the tow bar with a cable to prevent it from swinging when traveling.
