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?

Assuming he meant 50amps @ 120v...sure.
And since it's very rare for an RV to have 240v devices, the assumption of 120v is reasonable and yes, the big units can certainly be pulling more than 50 amps:
- 3 Air/con at 15amp each is 45amp
- Fridge maybe another 4-5 amp
- Water heater another 10 amp
- Battery charger another 10amp
- TV another 1 amp
- Microwave 7-10amp
- Ceiling fan another 4 amp
- RV Dryer 15amp(?)
If you have all these going simultaneously, that's somewhere around 100amps @ 120v...in reality, he probably has a load shedding device kicking in at this point as he bumps up against the peak draw.
