I agree at least a 1000 watt genny would be the minimum. A 2K watt unit would be the most versatile and still be manageable to carry along. Of course Yamaha and Honda are popular and don't forget Champion as they are well received and have great customer service.
I understand your viewpoint as we have an Onan that hasn't missed a beat under very demanding conditions for 10 years and 1K hours. For some of the same reasons we picked up a portable inverter genny although we haven't ever had any issues starting the Onan as we have solar as well.
