First question: IF you have an emotor on a trailer are you able to use it if you are driving the car, that is attached to the trailer and do you need to import any electronics? Second question: Can you make a simple Power take-off to that trailer without needing to use a bunch of rotators and couplers?
1. IIRC all vehicle inputs (including custom ones) can be utilized on any attached trailer while driving the truck. So if you assign a custom input to operate the motor on the trailer you should be able to use it from the truck/car 2. A mechanical PTO shaft between truck and trailer would need some kind of rotator and coupler setup AFAIK. Though if you want to use hydraulics for that their is already a good system for that which is used by the T-series and it's trailers.
