As MFL said, lots of opinions here, which I have found to be helpful. I'll relate my experience. I have an older (2004) 5th wheel with a 15K AC and 2800 watt (at 120 volts) Yamaha generator that is supposed to give a power boost for short term load. It will start the AC without any other high amp 110 volt appliances running. My problem is that if the converter is on when the AC starts (which is not predictable when both converter and AC are operating automatically), it puts the generator into an overload mode were it runs but does not put out power. Then I have to shut the generator down to get it working. So, for my situation, without other modifications, I need more power and am looking for a larger generator (the way I set up makes using two inconvenient).
