A 15000btu Air Conditioner draws 14amps running and 20+ surge when the compressor starts. That is 1680 watts running. Given that, your 540 measurement is incorrect.
I looked up that model generator and its 30amp twist-lock outlet is protected by a 25amp circuit breaker. With that said, your air conditioner and anything else running such as your Converter in your trailer will overload that specific generator.
Often the advertised ratings of generators are a stretch of the truth. In fact in that specific case, the continuous rating is 2850 watts not 3000 or 4000.
