At a recent birthday party my brother, my self, and my bride had a discussion about this. In the interest of clarity, I am copying his e-mail.
Please overlook my brothers outspokeness.
The last guy said what I said. Measure the voltage and if it's above 107VAC the air conditioner will run fine.
His statement that his multi-meter has a plus or minus 10% error is just stupid. If he is using a meter with such bad accuracy then he should not be giving advise on the issue. Any digital meter costing over $25 will have an error rate of about plus or minus 1%.
The only thing you need to worry about is the voltage while the air conditioner is running. If it's above about 105 you will be fine.
The other thing you can do is use a short (10 Feet) #12 conductor size extension cord and keep the distance from the junction box as short as possible. This will lower the voltage drop from the outlet. Also don't use a cable still on the reel. The cord must be completely unwound.
Keep in mind that a park that has only 20A outlets will no doubt have number 12 or higher cable running to the junction boxes. So their #14 wire will be short.
The last thing to worry about is to make sure you don't have other high current devices on the circuit.
Below is a voltage monitor which may work. If you are in the green regardless of the source of electricity everything is fine.
