OK....so this has been covered numerous times but I just had to post this. Recently,(yesterday and a few days before), while staying at one of my favorite Thousand Trails Parks( Rancho Oslo outside Sa...

How long did you run them and what was the ambient temperature? The real draw comes from the compressors and if both compressors weren't working at the same time, this is entirely doable.
Furthermore, a 30 amp outlet can put out 30 amps for short periods of time. Each of your A/Cs can run for a short while on 15 amps so 2 times 15 makes sense.
The bad news is that 30 amp breakers are only designed for 80% draw continuous, over one hour so you effectively only have 24 amps to work with on a continuous basis.
I predict that if you continue to run both A/Cs, you will trip the breaker in a couple of hours. If you don't trip the breaker, something is probably wrong with the campground breaker and should be checked out.
On edit: I see that the high in Santa Barbara was only 81 yesterday. Were you in the shade? My guess is that both compressors were not working together for long periods. Try this again when the temperature is in the 90s and you probably won't have the same result.
