I just learned the answer to your rotor question myself:
The Yaesu rotors will work on 12 vdc after modification. The mod involves
removing the ac supply, which provides 20 vdc. That supply is replaced with
a DC to DC converter. The one I've seen used is the 12 to 15 vdc model
available from DigiKey.
The rotor runs a little slower but otherwise works fine.
It's good practice to place the converter inside the rotor control box to
minimize radiated noise, run the supply and return leads with a few loops
through a couple of torroids also inside the box and fuse the DC
appropriately. Isolate the DC output return from the converter from chassis
ground.
Good luck, Bill
