Have to respectfully disagree with this. 6 round connection is used quite frequently for vehicles towed behind Motorhomes. Its not used for trailers, no, but it is the preferred approach for towing a vehicle behind an RV.
And, I think one 6 pin wire would be much better than having two separate wires and connectors to connect between the Motorhome and the car (one for the 4 flat, one for the charge line). A single 6 round wire would look much better and be much more organized, too, than having to run two separate wires. Not to mention, would be less parts to wear out, develop shorts, and have to be maintained.
