110V trailer plugs don't work.
Hi I have a 1994 Kit Companion Sunchaser 5th Wheel and I'm trying to figure out why the plugs inside don't work. The only one that works is the one in the kitchen. There are about 5 or 6 other ones th...

You can forget about the ground connections for right now, the only ones that matter for your 120V system is the connection to trailer frame and the connection within the load center.
Since you have used a long extension cord and lowered the voltage to the load center, I'd start at the shore power cord and make sure there is continuity on all three connectors. Since you have one receptacle working, one would assume it will be judged OK.
Next to check is the load center and the individual wires from the circuit breakers and the individual wires to the neutral bus. You could also check continuity from the neutral bus to any and all of your receptacles. The kitchen receptacle should show good continuity, as should the rest.
If all of the above checks out, you will need to determine which branch circuit powers which receptacles. This may be marked on the load center panel or you may have to trace with your meter. As was mentioned, trailer receptacles are usually daisy chained with the ones closest to the load center wired in first. The remainder will be wired along from that one in a chain. Look for loose wire connections.
You should also try to locate any hidden GFCI devices, under sink cabinets, outside the RV, etc. Test and reset the GFCI's. If they won't reset, there is no power present at the device.
Good luck with your power.
