The cord plug is another likely candidate for failure.
The best way to know is to check the voltages and isolate the problem.
I'll amend that statement as it's second best.
The best solution is to use a EMS like the PI HW50C. With it's display you can check the incoming voltage, amps, etc.
But most important IMHO is that a open or partially open 50A neutral can/will cause high smoke letting out damage to the electrical devices. The HW50C checks and doesn't connect and checks and disconnects when a problem is detected.
Every 50A RV should have one. I also had one experience with 160V on a 30A pedestal that occurred at night. RV power was shut off and I ran to the pedestal to unplug.
