    Update - It was a wiring harness in the vehicle.

    Nothing is simple or cheap in new vehicles.

    Put a good clean grind to the trailer frame, re-attach the ground wire and try again. If you have a multimeter you can check the ground on the vehicle side BRANCH SWIVEL-NICKEL PLATED - BR-SWIVELNP-XX. I've had trouble with this before and the trailer lights would work after a few bounces down the road it would ground through the hitch but the vehicle ground through the connector was corroded where bolted to the frame
