30 amps for 50 amp trailer
Hello. I am thinking of going to a campsite where the only site available is limited to 30 amps. I know I can get a converter plug and hook up, and I understand that only one of my A/Cs will work. ...

OK,first, I have 50 amp service and have stayed at places without 50 amp available. It is possible to use an adapter that runs to both 30 amp service AND 15/20 amp service giving you the ability to run everything you normally would. As stated, I have had to do this multiple time with no problems what so ever.
50A service isn't the same as 30A + 20A service. It's more like 50A + 50A service.
50A service gives you two 50A legs, 30A + 20A would give you at most 30A on one leg and 20A on the other, so you may still trip the breaker if you run the A/C and electric cooktop(s) at the same time. Or even an A/C unit alone can trip a 15A breaker.
Plus they may tap the 15/20A downstream of the 30A breaker, so even if you plug into both, so you may still only get 30A of current.
And 50A RV service is normally (but not always!) split phase, so you can get 240V across the hot legs. I've seen 240VAC dryers in some of the bigger class A's, so even with a 2 plug adapter, you may not be able to run "everything".
And one other drawback -- it won't work when the 15/20A outlet is GFCI protected, it will trip the GFCI.
