I would not run the Air Conditioner, and you may find that the microwave will cause the circuit breaker on the hookup post to trip, but I don't think you'll damage anything. Don't forget to buy an adapter for the plug. If you have an A/C voltage meter, monitor the power to be sure it is okay.

Amps = how much you can run at one time
15 amps = Microwave and possibly Fridge..
In place of Microwave you can run Water Heater or Air Conditioner depending on size.
NOTE that state of charge on your 12 volt batteries WILL MATTER on a 15 amp line. (If batteries are low that replaces Microwave too, I can suck near 20 amps with low batteries)
In short, Converter with charged batteries, Fridge Television and ONE big ticket item is possible on 15 My "Storage pad" has 20 amp and I often run that arraingment w/o problem
30 amp gets you a 2nd "Big Ticket" item (You should only have 2 of those in your rig) 50 amp gets you a whole bunch more (six big ticket items possibly 8 if properly blanced.. Since I only have 4 big ticket items (not counting converters) that is everything Converters are "Big Ticket" only when batteries are dead. Big Ticket is more than five amps draw

I guess I've been lucky, but are there RV Parks with ONLY 15 circuits? Not 20? I noticed he said they have no 30 amp service, but are you sure there is not a 50? I have been to RV parks without 30 amp service, but they have a 15/20 and a separate 50. If they have the 50, connect the dogbone and enjoy.

That would be my question. I've been in several places where all they have is one 15A outlet, but it was protected by a 20A breaker.

I've heard of those, but never seen it myself.
I could see it in either high end parks where us little folks don't venture, or in one wired minimalist. The NEC requires 70% of the sites to have 30A and 5% to have 50A. They could make some have only 50A and still meet the NEC.
You must remember, also, that most 20 ampere configuration has two parallel slots and the hot leg has a perpendicular slot. Yes a true 20 ampere has 2 slots perpendicular to each other. I am not counting the ground slot.
Many parks call their receptacles 15 ampere where in fact they are 20 ampere.
Older parks are not required to update to newer NEC requirements as times changes. They can maintain to original installation. Dumb to do so but end dollars is what counts.
Capitol Lake MY TT will run even the AC (13.5 unit) on a 15amp circut, however it will not run AC and micro at same time. Like mentioned above the breaker will shut you off if you try and run too much at same time. I have had no problems using a 15 amp service at campgrounds or at my house.
You won't be able to run the AC, coffee pot, or the Micro for starters. The smaller items such as the converter, TV, fridge etc. should be all right. The only catch is that you'll be depending on their breaker to trip if amps go high because of a voltage drop. A voltage drop can harm electronics without warning.

What appliances do you want to use, and how big is your air conditioner?
A 7,000 BTU/hr unit, 6 amp continous draw, will run on 15 amps all day, but probably not with too many other loads, and not with a microwave drawing 10-12 amps.
My 15,000 BTU/hr, 12 amp continous draw, will pop a 15 amp breaker in about 20 minutes with the converter also in use. My A/C will run indefinitely on a 20 amp circuit, but the microwave at the same time will trip a 20 amp breaker. Sometimes, microwave + A/C + toaster will trip a 30 amp breaker.
Other size A/Cs, the answer is somewhere in between.
The electrical needs and service limitations for 35-foot fivers, 30-foot travel trailers, 40-foot motorhomes, B's and popups are not the same.
Make sure you have at least 108V inside the RV, while you are running whatever you are running.
Just because a breaker doesn't trip, doesn't mean its safe. Breakers have 2 means of protection, a short circuit and overdraw. If you are running an A/C and the start up is pulling enough amps to heat and trip the breaker, it could also damage the compressor if the heat and connection drop the voltage. The windings are designed to operate within certain bounds, and if amperage goes high enough it will heat the windings and eventually destroy them.
