Yea I'm not sure if you saw this video I added:
https://youtu.be/dkoFvA6x6XE, but motor is turning the connecting rod (but the motor is rotating with it).
One thing I also just realized is that after the gearbox broke, I wasn't able to manually extend or retract the landing gear either, so I wonder if this says anything about the issue.
Also the trailer is a 2007 montana mountaineer edition 342pht
