Crack Down on 50 Amp Rigs Using 30 Amp Sites

using a 50-30 dogbone, the (2) legs from the 50amp connect to the one leg of the 30

you are not power only one leg of the 50, if of half of the rv circuits would have no power

Veebyes said 20amps on each leg, that is 40amps total
a 30amp service won't support 40amps

this is not about the pedistal box, or the 30amp outlet components
it is about the fact the NEC code in effect at the time the rv park was built

its not about one outlet, its about load factor allowance from the old code
and newer rvs using more than the installed circuits can carry

The current code still uses a 50 percent load factor, that hasn' t changed. What has changed is new park construction requires a higher percentage of 50 amp services (that may not be a NEC requirement, it may fall under a different building code provision.). A circuit of 30 amp services will face the same load factors and the resulting limitations if they were constructed in 2018 or 50 years earlier.
