Sure sounds non-Kosher to me. I know the AHJ can modify code enforcement in various ways, but this one seems... unusual. As in not enforcing minimum standards unusual.

I am not an electrician.

But a 30 amp RV will trip its 30 amp internal breaker before the shore cord overloads.

You plug your 5 amp residental fridge into a 20 amp outlet.

That is correct however it only applies to your shore power cord. once the juice get to you 30 amp panel it is controlled by your 30 amp main. So if the shore power got damaged or got hot due to a loose connection, it would have to wait till the 50 to trip. Heating up you 30 amp cord causing more problems. If you overloaded the cord with 2 a/c's and say a water heater the 30 in your RV would trip.

Back to your question, simply turn off your main breaker in the coach, plug into their outlet, turn on your main panel circuit breaker. Of course you test it first for correct wiring. I've plugged into several of this type outlets across the U.S.A. without issue.
In fact the only time I did have a problem was with a 30A pedestal that was protected with a circuit breaker; it was wired incorrectly.
