Another problem area that is very hard to diagnose a fault is the truck's trailer socket connection. If a wire in back of the connector is hit by road debris, it may be enough to part the wire inside the wire jacket. You won't see it and it will intermittently connect/disconnect. I had this issue and discovered it by jiggling wires. The cure was to remove the socket, disassemble it, strip wire for good connection, and reassemble. Be careful, my Ford had a lot of small pieces.
