Anybody know where junction would be for lights/ cord on 3251 Sanibel fifth wheel? Have front running lights, no rear lights at all,( have 4 ways and turn signals), ( truck, cord everything ok), problem is in the trailer, or under it?
How about the rear DOT lights? You have 4 ways and turn signals, how about brake lights? If they are working, I would check the bulbs for the tail lights.
If all your clearance lights & marker lights are working then yes, check the bulbs first (unusual for both to go out but......). Then, if that doesn't work drop the underbelly in the rear and start tracing the wires from the taillights forward. There is likely some splices for the marker/clearance lights and the taillight wire may have come out/broken.

I have the same 5’er. Been thru this, marker lights were installed upside down, filled with water after heavy rain, dealer took them all apart, ‘sealed ‘ them. Also license plate light was shorted, cheap junk, replace that also. Good Luck
