Pulling more than 50 amps ?
Our park electrician says that some of the big rigs with 3 ACs and electric everything can sometimes draw more than 50A from a 50A pedestal. Truth or BS?

Ask what conditions are necessary to cause a breaker to trip.
There are two ways for breakers to trip. One is thermal where the heat build up from running near or at full capacity for some time causes the trip. The other is a "magnetic" trip where the amp rating is exceeded for a time. We don't want nuisance trips from, for example, start up surge from the air conditioner.
So yes, for brief periods of time, a 50 amp service may exceed the rated values.
