I have a 4000 KW Onan generator in my 2016 Winnebago, can anyone tell me what the fuel usage is per hour in the generator when under load. It is a gas unit...
Generators can be engineered to be VERY efficient because they only have to run at a single speed, albeit under varying loads. The designers can then optimize the design for just that speed. This is unlike the engine in your car or coach that has to be able to run all the way from idle to redline.
