    The Cummins Onan QG4000 is a great entry-level product for RV generators. This model features Cummins Onan 4-Cycle OHV engine for the most electrical output for your dollar. If you are looking for a no-frills design or watching your expenses, this will definitely get the job done, but might not give you the peaceful experience you were looking for. This unit is ideal for light and medium use applications and will handle all of your basic power needs.

This model will run quietly enough to meet the standards for National Park Service sound levels. Cummins Onan RV generators can be found all over the road and in RV parks. This entry-level diesel model earns its recommended status.

    Best Propane RV Generator

    Learn More About Cummins Onan A063B873
    Expert Review
    The Cummins Onan 5.5kW is also a nice model that will handle most light and medium use applications. The Cummins Onan has the benefit of a Sound-Attenuating Enclosure with a Thru Flow Cooling System so the noise volume is lower. By selecting a propane model, you are also helping reduce noise volume. In addition to superior noise reduction and fuel efficiency, one-touch start and self-diagnostic technology make this unit easy to operate. The perfect LP unit for Class B and C motor homes, sport utility trailers, towable applications and fifth wheels with a single or dual roof air conditioning. This generator is another great item, but may not power your entire RV. Before buying this generator make sure you know the minimum amount of power you desire especially considering a propane model can reduce power output by up to 10%.
