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?

i've heard of but not seen in person RVs with 100-amp service. connected to a 50-amp post i believe the most a rig like thar could draw would be a bit less than 50-amps else the post CB would trip.

fcooper is right. You are not thinking about how a 50 amp / 240 Volt system works.
You have 2 120 volt legs with 50 amps available on each leg not 25 amps on each leg. 50 + 50 =100 amps of 120 volt power.

Three? Each is maybe 16 max so even 4 would pull only 32 per side max.
Licensed electrician or handy man?

Stating an amperage without specifying the voltage is really only describing part of the story. More than 50A @ 120V? Sure. More than 50A @ 240V? Sure... for a few seconds until the breaker pops.
Honestly, RV power is listed in kind of a messed up way and it rarely gets clarified. A 30A hookup is 120V. A 50A hookup is 240V. So, if you just want a linear scale for comparison sake, a 30A hookup is 30, a 50A hookup is 100.

Add up all the possible loads. Neither leg will exceed 50 amps I suspect--but there are 2 legs.
In winter I can draw more than 50 amps--but it is shared over both legs.

Electrical must always be designed for worst case.
Aside from water heater, reefer and battery recharging it is quite possible for a park power blip to knock all A/C off line. Then all of them may attempt a high head re-start. If the park is nearly full, the park becomes an involuntary appliance durability tester.
