No Tail Lights

2014 Coachman Prizm on Mercedes Chasis. No tail lights or rear marker lights.

Brake, turn signal and back up lights all work fine. Checked Coachman fuses near bedroom floor and Mercedes fuses under steering wheel and under driver seat (although none are identified as being related to tail lights)...all visually fine.

Any suggestions on where to look?

Thanks in advance

Trace the feed wire from taillight back to it's origination, testing for 12V at every connetion or splice until you find power.
Have you tested all the light bulbs for continuity? Although improbable, they can all be blown for some inexplicable reason.

No lights on rear of unit is usually a ground problem. I found upon opening up my rear brake/turn light assemblies that Forest River used closed end crimp terminals using a single ground wire. Stick in 5 wires and crimp. Not a big fan off those so I cut off crimps and soldered all splices.
