The biggest problem when on a 50A circuit is the CG wiring. If their neutral is not solidly connected and you "heavily-load' one leg, bad things happen.

Our coach has a relay that turns off the rear AC unit if the washer/dryer is running.

Sometimes I post what I call the rules per Readdy Killowatt.
20 amp 1 Big item
30 amp Two Big Items but not both A/Cs
50 amp---- All you can eat
The full post explains what Big items means (over 1,000 watt) but I'll skip most of that.

We've only had problems twice, when plugged into 50 amp.
One was a fake 50 amp. Instead of 240 volt 50 amp, it was 120 volt 50. 25 amps per leg. Why if I had paid more then $3 per night I would have been offended.
The other was just a while ago, 80% breaker. It tripped anytime it got above 40 amps, on either leg. I thought they had a faulty breaker, till I when out to inspect. They had a big sticker on the inside about it not being a bad breaker, but was a 80% trip point.
Where we are now, I'll have all 3 ACs and both electric elements in the Oasis on at the same time.

Some of the power pedestals in the United States Army Corps of Engineers Permission Hill campground, (on Enid Lake, in MS), are labeled as follows::
WARNING:

I'm thinking there's room for the " Military Intelligence " saying there , labeling it a "35 amp draw only " pedestal would have at least saved some letters on the sign.
