Yes it’s 50 amp, and yes it seems one leg is out. So is it possible to lose part of the power at the pedestal? The breakers to the pedestal are not tripped, but it’s been raining like crazy and that pedestal is in a huge puddle.
Yes it's possible even though the breaker feels ok when operated. When you can get to it, turn the pedestal breaker off, unplug the 50 amp cord, turn the breaker back on, and use your meter to test for ~240 volts between the two side slots, and/or ~120 volts between each side slot and the third slot, usually at the bottom of the outlet. The round hole is for the safety ground connection, and is not a factor with this problem.

Thank you for that info. I will try that.

Thank you so much to all that responded. Hopefully, one of these suggestions is the culprit.
 
Do not mess around with shore power pedestal if it’s water. Take the front cover off your entrance panel and check for voltage there on both legs. If one leg is dead, then it’s either your cable or the CG pedistal
Do you feel comfortable doing that?

I am an electrical tech by career and I pretty much agree with what NYDutch is saying in post #21. The circuit breaker at the pedestal for your 50A plug should be 2 breakers that have the handles locked together to operate at the same time. Since you have 2 GFCT outlets it is typical of 50A RVs to have 2 separate 120V circuits for the outlets and one to be connected to L1 and the other to L2. A good double breaker will always have both sides open or both closed but for one side to fail is one of the more common reasons that they have to be replaced. A GFCI will not reset if there is no power to it, which pretty clearly indicates that yours are on different legs of the power supply and one is good with the other open. You can expect the RV park to resolve this problem.

Oldgator, that's not always true. My converter has two outputs. One goes only to the kitchen and the outlet In the cabinet below the kitchen and the other seems to be everything else. Each output has it's own breaker.
 
50 amp is two separate circuit breakers riveted together and having the handles tied together, so its quite possible one side of the pedestal breaker, or the main breaker in the RV failed internally without tripping open. Its also possible you have a loose connection in the pedestal or in your breaker panel in the trailer.

It will require a methodical checking of connections starting at the pedestal. With all power off, shore unplugged, you need to open up (or have a qualified tech do it) and tighten up all connections on breakers and ground and neutral bars. A trailer is a rolling earthquake and stuff tends to loosen up over time.

"The converter in an RV takes 120V-ac power and converts it into 12V-dc power."

Mine is a converter/inverter kind of like the one shown In the attached pic. AFAIK all A/C in my RV goes through it. If the two breakers are off nothing works except the 12v 'stuff'.

Not "all" of it - you can be sure the roof a/c unit power doesn't pass thru the inverter, and probably some other 120v appliances as well, e.g. water heater. But yes to most wall outlets, microwave oven tv & entertainment stuff, etc. That is done so that they work the same whether on shore/generator power or inverter.
