Your electrical needs, if you want to use the air conditioning, can vary on what other uses you have. I am going to post a few links to existing threads on what amperage circuit you need, depending on the size of your A/C. If that Camping World adapter is what you plan to plug into a 15 amp circuit, you will not be able to run your A/C safely IMO.

You also need to pay attention to the length and American Wire Gauge [AWG] size of your extension cord, if any. If the trailer's umbilical cord cannot plug directly into a duplex receptacle ("outlet"), you should probably consider having a #12 AWG extension cord, not longer than 50' or so.

My knowledge is limited in this matter, so other than the links to follow, I will bow out here.

Good luck!

Peter

And those of you that leave it this way, will it run your AC unit?
There is no answer that is correct for every situation. You need to know a few things.
1. If you only charge the batteries, nothing else, yes that adapter is perfect.

2. What size is the circuit that you are plugging into? A residential plug that will accept the adapter you linked to can be either 15 or 20 amp 120v alternating current. A 15amp MIGHT start your air conditioner if you turn off everything else, EVERYTHING!! If it starts it might damage the AC in the long run. If you plug in anything else, it will trip the breaker. There possibly could be damage to the AC if it is run with low voltage for extended time. (the AC manufacturer's specifications say "20 amp" circuit is the minimum size power supply and also limits the length of 12 ga wire in the circuit, if memory serves me, to 24 feet)

2. If that adapter is rated 20 amp AND your receptacle is rated 20 amp AND that receptacle is on a 20 amp circuit breaker with the correct ga wire AND the total length of wiring in that circuit is short enough that there is little loss of current, then I would say it will run the AC unit without damaging anything. BUT, if you turn on something like your hair dryer it will begin to overload the circuit.

3. Even if you have a properly installed 30 amp RV circuit you still have to consider every item you plug in. Remember the converter is always plugged in, using 120v power to charge batteries and power all 12 volt items. You may have the refrigerator on 120V. An example: if you run the AC during hot weather or a small electric heater in the winter and at the same time you want to use the electric coffee maker, all is well. But while you are waiting for coffee you decide to turn on your hair drier. Something will trip.

You will learn how to manage loads pretty quickly, because tripping breakers and melting cords will educate you. Replacing an air conditioner gets expensive!

IMO, you will need to have 30 amps if you are living in it full time, or forgo air conditioning and electric space heaters.

It sounds like you need to talk to someone who understands electricity and can look at your specific situation. There are quite a few people on this forum who can advise you. IF you are comfortable doing so, you might post your location (city and State) and see if such a knowledgeable Airstreamer is close enough to you to give you some personal advice.

Ugh! Yes! I need help! I'm going to look at two places sunday and will need to be able to assess the electrical availability. I'm in Atlanta, GA.

My refrigerator and stove etc run on propane. It would just be for ac, heat, and phone charging mostly, maybe a salt lamp. I don't use a lot of power.

The air conditioner sets the bar for your electric needs. If you tell us what your A/C is, better advice can be given. You probably need at least a dedicated 20 amp circuit for the trailer, but 30 amps would be best (assuming that you have the 1973 31' Sovereign shown in your sidebar ID).

There are many other variables, as mentioned by A W Warn, but knowing your actual A/C would make for a good start. The distance from the trailer to your plug-in location, and the electrical setup at the new location(s), will also come into play.
