The 15 or 20 amp receptacle on the pedestal is required by code to be GFCI protected, either by a GFCI breaker or GFCI receptacle. The receptacle is a fraction of the price of the breaker and more often used. This has been code since the late 1970s, so if you find one that isn't GFCI it was likely replaced by someone or the inspector missed it. A GFCI will by it's function will absolutely not work on a shared neutral. It measures the current on both the hot and neutral and if it senses more than 5ma difference between the 2 it assumes it is leakage and trips. In this case both outlets are sharing a neutral to the coach.
