Champion 2500-Watt Dual Fuel Inverter Generator

I have an open frame non inverter Champion generator dual fuel 3400 I think. It's great. Not really that loud. I also have a Honda 2000i and when it is working in high mode, it is as loud or louder than the Champion, when it kicks down, it is not as loud. On a recent trip, we used the Honda because we did not need AC, my kids and wife all asked why we didn't bring the Champion because they thought the Honda was louder.

But, to the OP question, I think the Champion is a good unit and have no issues with it service wise. I have only run it on propane.
