Lost all lights on rear of Class A

[boro3]

Have a 2002 Damon Ultrasport with a Freightliner chassis. Recently lost tail, brake, and running lights. Replaced a relay and checked fuses, no luck. Anyone have any ideas?

I would try replacing the fuses (something suggested to me years ago by an electrical engineer)- also call Freightliner and see if they can help- talked me few an issue or two when I had the MH

Chances are the only thing all these circuits share is a single ground connection.
