I have a 2003 Four Winds 31P. The coach has been laid up for a few years. I seem to have lost electrical power on the passenger side of the coach. The outlets on the drivers side all work. Any sugges...
Did you firmly turn the breakers off and firmly back on to reset any tripped condition.
Otherwise I would remove that GFI to verify if there is a feeder to other outlets and measure voltage is present. Then start removing all outlets to measure voltage along the entire circuit.
If the dead circuit includes a slide check for issues with the external flexible connection.
