RV Generator FAQs
This depends on what kind of fuel your RV uses and how much power you will need. For example, if you want to be able to run two ACs, a TV and the microwave at the same time, you will need a fixed-mount, high powered generator. You will also want to consider whether you are replacing an old generator or if you are installing a generator in an RV that never had a generator. If you’re not sure which generator is right for you, find a dealer near you to help you find the right one.
RV generators come in many sizes ranging from 2,500W to 12,500W generators. Their basic working principles remain the same. The internal combustion engine converts the chemical energy stored in the fuel to mechanical energy, rotation. The alternator, coupled to the engine, converts this mechanical energy to electrical energy. This electrical energy then flows to your RV’s circuit breaker panel to feed the loads, equipment and appliances within your RV.

Yes, that is what a generator is for: portable electrical power. In fact, it can help lower fuel consumption because the generator uses less fuel than your vehicle engine. Plus, it gives you an opportunity to exercise your generator. Any appliance that can be run in a stationary position can also be powered while driving. This only applies to fixed-mount generators, not portable generators. For more details on this subject, refer to page 21 of the RV Handbook: 5410860 RV Generator Handbook (F-1123).
