For additional info.
When we had our old trailer with 13k A/C I used a Yamaha 2400 generator to run it. The newer A/C's have bigger capacitors for starting so use less surge. I did have to set the fan to on rather than auto. Trying to start the compressor and the fan at same time was too much for it. Needless to say, not much else could be turned on when the A/C was running. Refrigerator and water heater set to run on propane. The other nice thing was, at 75lb, I could lift it into the back of the truck (barely).
For our current trailer am looking at dual Champion 2000's or Ryobi 2200's.
