We bought a 2016 Born Free Class C RV on a Mercedes chassis. We have been experiencing an intermittent problem with all of our exterior lights not working. No brakes, back up, turn signals or running lights. When the RV is in Park they go out, so we never know if they're going to work or not. Any ideas?


The exterior lights are all part of your chassis' electrical system and not your coach electrical system.

Personally, I would first call Mercedes Customer Service and get them to explain what the problem might be.

I suspect the RV will need to be taken to the Mercedes dealer for them to check the problem out for you.
