Experiences with Onan Portable Gas Electric Generators

My Honda 3000 starts even 15k AC on ECO mode and that's with charging and like 150W Water heater element on.
Than I hear more and more that adding easy start to AC makes it running on 2000W quite possible.
So even there is nothing wrong with having bigger generator, where are you going to carry it?
Than I drove via Oregon twice this summer. Never run generator in the state.
