I will say you can run one AC with 15 amp circuit with a soft start on the AC. However, you will trip the breaker if you try and run the microwave at the same time. You will want a minimum of 30 amp, 120v for the single AC. If I were going through the expense, I would put in a 50 amp. If down the road you decide you want a second AC, you will either need to redo the work or add soft start. If I had a stationary unit, I would go 50 amp from the start. Then you don’t need to worry about overloading anything. Now, a little bit about RV electrical system. They are 120v, but two legs of 50 amps. Make sure your electrician understands this. Lots of horror stories about people getting zapped by 50 or 30 amp 240v and destroying their electrical system. Hope this helps.
