Most RV generators need to be serviced every 100 hours or once a year, whichever comes first. But some factors can affect how often you need to service your generator such as how often you use it and what type of generator you have.
For example: If you have an air-cooled generator, you may need to service it more often than a liquid-cooled generator. And if you use your generator regularly, you may need to service it more often than if you only use it occasionally.
And remember, regular maintenance is the key to keeping your generator running properly and extending its life.
