Thinks for the responses on the noise. I actually think more about the noise bothering neighbors than myself, so I think I would pass on the Champion for trailer use. Honda really seems the way to go, extra cost or not. I recently saw a video test comparing the Honda vs Champion 2000 models. Champion seemed to not be able to handle near the load of the Honda. One at a time they had them both connected to a table saw and the Champion would cut out every time the saw was turned on. The Honda kept right on chugging along.
