most likely they will be on the same circuit from what I have seen - if they do not have power it would be hard to tell which circuit they are on
got a silly question but why would you start from the furthest one out that isnt working instead of starting at the good one and working your way out?
I know everyone has diffrent troubleshooting techniques but just curious
Another option is to cut all power to the trailer and use a fox and hound (toner) to see if you get tone on each socket - this would be a way I would check it if I didnt feel like opening all the sockets even though now thinking about it - I would take all the sockets and check all the connections so this never happens again.
