In Mexico using the A/C unless absolutely necessary is a no no (we will run our generator if it comes to that). Many parks have inadequate wiring with too small of wire size to carry all the amps required if very many RVs tried running an A/C. Maybe there is a 20amp or even 30amp breaker and even the correct outlet. But we have often seen that the wiring in the main and the wire running to sites could be undersize. For those with any electrical knowledge - we have seen #6 wire running from the main breaker to about 20 spaces with 30amp outlets. Can't work. Even the wire from the transformer was undersize and the transformer was not large enough to provide for that many spaces - or even a few running A/C. We have personal seen main breaker wire burn and melt as too many try running too much stuff. I suppose it depends on where you are but in many cases in Mexico using an A/C is depriving others in the campground or RV park of having adequate power. And electricity in Mexico is very expensive so either the park owner has meters to charge users for what they use or the park owner has to pay for the excessive use and then he has to raise space fees for all. Only those inexperienced with Mexico use A/C unless absolutely necessary. Some parks just have low amp breakers so A/C cannot be used.
