20 Amp Circuit to Support 2nd A/C Unit
I'm pretty sure one of you have already done this the easiest way, so no need for me to reinvent the wheel, right? My trailer is a 30 amp system, so I believe the easiest/cheapest method is to add ...

I would run the separate 20 amp cord.
Only time you should have any issue is when the parks voltage is low.
OK, from the power pedestal, how would that be constructed? I assume that this is plugged into the 20 amp receptacle, which shares a power source with the 30 amp circuit.
The question is not whether they share the same power source. The question is whether the 20 amp breaker is wired in parallel to the 30 amp breaker, or is the 20 amp breaker wired down stream (i.e. in series with) of the 30 amp breaker. And I would guess there is no way to know without testing each to know which way any given park is wired. Wired in parallel you would have up to 50 amps available. Wired down stream you would only have a total of 30 amps available.
Wired from the same source probably just means from the same hot leg so that there would not be 240 vac difference between the two.
