Generator question

Here and there you will hear someone say they are doing it and it then gets into hard start capacitors etc. I run my 13,500 on a Honda eu3000si and it does fine. My coachmen owners manual said use 4,000 watt gen. They are giving more cushion as people do when they say get an inverter that is bigger than you need so you are running it at a lower point in it's operating range. You know, so it's not flat pedaled all the time. :)
