The nice thing about the Honda EU series generators is you can gang two together. So if you have 2 2000 watt generators you can run them in parallel to get 4000 watts, with the adapter kit that you can buy from Honda, of course.

You want to remember to derate the power capacity. They're really only good for about 80% of the power rating. So a 2,000 watt would deliver about 1,600 watts continuously. You can get more out of them, short term, but, if you want them to last, only use them at 80%. This is common advice from many experienced RV'ers.
