Gut feel says have a separate wiring set up for towing the vehicle, with a connection in the front that will connect to the coach. I recommend this because it is not clear how the wiring was done for the vehicle to tow a trailer. Also, if possible, the connection being in the rear of the vehicle would make for an interesting run to the coach. You're looking at a long term setup. Do the safest solution.
