Leadership Alliance – Cummins Onan

The Leader From Day One

Cummins Onan RV generators are built by Cummins Power Generation, the global leader in generator design and construction. For over 80 years, our generators have been providing reliable stationary and portable power for cities, hospitals, shopping centers, military vehicles and fire engines around the world.

When mass production of RVs was in its infancy back in the 1960s, Onan led the way in reliable mobile power. Today, Cummins Onan offers the most diverse lineup of RV generators in the industry. From gasoline, LP and diesel units through our new hybrid models, only Cummins Onan offers the most complete line of generators designed specially for all motorized and towable RV applications. With our 2,000,000th RV generator shipping in 2010, there are more Cummins Onan generators on the road than all other brands combined.


Cummins Onan RV generators are designed to enhance the RV experience. Quiet operation, compact configuration and easy servicing are the hallmarks of our industry-leading generators. This starts at the design stage, where our engineers put over 100,000 hours into developing each new model before putting them through extensive testing. Our commitment to engineering for exceptional performance is why we have the competitive edge with generators that are smaller, lighter, quieter and better for RV use.

Your generator’s operating noise can make or break your fun times, whether it’s socializing at a campground or boondocking in remote locations, so we put special effort into producing RV generators that emit the lowest operating noise levels available. This means inclusion of elements like advanced enclosed mufflers and cast bases on larger models, both of which provide a solid foundation for reduced vibrations so you can enjoy nature and sleep peacefully through the night.

Each RV generator is configured to ensure it provides the enhanced power required by RV appliances and delicate electronics. From the smallest gasoline model to the newest diesels with pure sine wave output, Cummins Onan-installed generators meet or exceed the RV industry’s power quality standard. Whether you’re using a toaster or a laptop computer, you can trust your Cummins Onan generator to deliver consistent, quality power. Plus, the compact configuration of an RV generator from Cummins Onan means having more room for your gear and greater payload capacity.


Cummins Onan RV generators continue to provide rated power on even the hottest days and at high altitudes. Internal combustion engines can suffer power output losses of up to 1% for every 10°F increase over 85°F ambient temperature and 3.5% power loss for every 1,000-foot increase in altitude.

Cummins Onan RV generators are built with the power margin to maintain performance under these extreme conditions. This is an important distinction when considering which generator to use. In desert heat or high in the mountains, your Cummins Onan generator is built to out-perform the competition.


Cummins Onan RV generator owners are supported by the largest service network in the business with over 1,000 dealers, more than 130 Cummins Distributor locations and 39 Coach Care RV service network locations in the U.S. and Canada.

Every one of our generators comes with an industry-leading 3-year/2,000-hour limited warranty. This coverage can be extended to five years and may be transferred from the original owner to the next if the RV is sold during the warranty period.


Cummins Inc. was recently honored by Newsweek magazine for its efforts to minimize its environmental footprint and reduce greenhouse gases. We earned a ranking in the top 20% of the 500 largest companies in the U.S. singled out for this recognition. This came shortly after being named to the Dow Jones Sustainability Index for the fifth consecutive year. For the RVer, this commitment to environmental responsibility is demonstrated through engines and generators that operate on 20% biodiesel fuel, advanced autostart systems to minimize generator fuel consumption, and the introduction of hybrid generators that reduce fuel consumption, emissions and noise.

Because we provide the best combination of engineering, performance, model choice and nationwide support, when you choose our generators to power your travel adventure, you choose dependable products from an innovative and conscientious company.
