We came home from our 2 week vacation and plugged our rv into the rv plug in our rv port. A few days later my wife told me that we did not have 120 volts. So I unplugged the cord and got my volt meter out and sure enough no volts.....so I went to where it is connected to the master switch and 120 volts there so some where under the concrete the power disappears. Something is amuck.....
Where is this "Master Switch"? , what does it look like, and did you check for voltage on both sides of the switch? Maybe the switch is bad. And if the switch is also a circuit breaker I've seen times when even if there turned on and not showing red in the window they can still be bad and not letting power through.
