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?

Rig could potentially draw 100 amps over both legs. The rig should be wired to put less then 50 amps on each leg. The system is design with load calculations done at 120/240 volts.
Old campgrounds in some cases do not have a properly wired 120/249 volt system. They modified a 120 volt system by connecting both terminals to the same leg. This can overload and can cause damage to the neutral conductor in the shore power cord assembly.
The 50 amp 120/240 circuit breaker could trip if voltage drops increasing amperage.
Calculations followed by true amperage readings is the only way to know for sure.
Some larger rigs have power center that can tell what amperage is being drawn.
