Features to know about

Power for RVs, Homes, and Jobsites

When you need more than basic backup power, this portable inverter generator is built to handle serious demand. The 457cc engine delivers up to 11,000 peak watts and 9,000 running watts on gasoline, giving you the output needed for large loads like RV air conditioners, home essentials, and jobsite equipment.

Fuel Options That Fit the Situation


Onan portable generator

Fuel availability can change depending on where you are and what you are using the generator for. This tri-fuel system runs on gasoline, propane, or natural gas, so you can choose the fuel source that best fits your RV setup, home backup plan, or worksite. A control dial makes switching between fuel types straightforward.

Remote Start Without Walking Back to the Generator

Starting a large generator should not require extra trips outside or across the campsite every time power is needed. The remote start system includes a key fob with a 99' range, giving you convenient control from a distance. An onboard push button start is also included, along with a pull cord backup for another startup option when needed.

Safety Monitoring for Carbon Monoxide

Generator safety matters, especially around homes, RVs, and busy jobsites. The built-in carbon monoxide detection system monitors for dangerous CO levels and automatically shuts down the unit for added protection while the generator is in use.

Power Connections for Larger Setups


Onan portable generator

Different power needs call for different outlet options. This generator includes a 120/240V 50A outlet, a 120/240V 30A outlet, a 120V 20A GFCI duplex outlet, and 2 USB ports. That gives you connection options for RV power, larger equipment, household essentials, and small USB-powered devices.

Runtime for Extended Use

Long runtimes help reduce interruptions when you are powering through an outage, a workday, or an extended RV stay. This generator delivers up to 16.5 hours of runtime at 25 percent load on gasoline and up to 13.4 hours on a 40 lb propane tank.

Quiet Design with Real-Time Monitoring

High-output power does not have to mean constant distraction. The enclosed and insulated housing helps protect internal components while reducing operating noise to as low as 64 dB(A) under load. An LED display also keeps key information visible, including runtime, fuel level, voltage, power output, and total hours.

Maintenance Access When Service Is Needed

Routine upkeep is easier when key areas are simple to reach. Service access panels help make maintenance and oil changes more manageable, so you can keep the generator ready for RV use, home backup, or jobsite power.

See what our Experts say about this Cummins Onan Generators

  • Is Onan 11,000-Watt Tri Fuel Portable Generator Quiet Enough for Campgrounds
    Hey Bill! For an 11,000-watt generator, the Onan # CM98MR is actually pretty reasonable for RV camping. Cummins rates it at as low as 64 dB(A) under load, which is noticeably quieter than a lot of traditional open-frame construction-style generators in this power range. A big reason for that is the inverter design. Instead of constantly screaming along at full RPM, the engine adjusts speed based on how much power you're actually using. So if you're only running lights, chargers, or a few...

  • Is Onan 11,000-Watt Tri Fuel Portable Generator Capable of Running Two 15k BTU AC Units
    Hey TIm! Yes, the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR has the capacity to run two 15k btu AC units simultaneously on your 5th wheel. This has 11,000 starting watts with 9,000 running watts on gasoline, and is built for larger setups like yours that need enough power to run multiple high-demand appliances at once. This generator has enough overhead to handle those startup surges without constantly tripping breakers or overloading. You'll still be able to use smaller appliances...

  • Can Onan 11,000-Watt Tri Fuel Portable Generator Use Ethanol Free Fuel
    Hey Pete, yes the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR can use ethanol free gas. In fact, that's actually the preferred gas to use. Is this for your RV? Is ethanol free gas easy to source in your area?

  • Can Onan 11,000-Watt Tri Fuel Generator Run at High Altitude
    Hey Nathan! Yes, you can use the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR at those elevations. However, Cummins requires a high-altitude kit when operating above 2,000'. The kit you need depends on which fuel you're using. For gasoline, Cummins lists the # CM65FV (A069E131) High Altitude Carburetor Kit. If you're running propane or natural gas, they list the # CM75FV (A069E132) High Altitude Fuel Switch Kit. You'll also want to be mindful of your overall power usage at higher...

  • Should I Run Onan 11,000-Watt Tri Fuel Generator on Gas or Propane With Two AC Units
    Hey Eric! I would run the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR on gasoline when you want the most available power for both AC units. It produces 9,000 running watts on gasoline compared to 8,100 watts on propane and 7,200 watts on natural gas. Propane is still a great option when you don't need the generator's full capacity, especially since you're already carrying it for your 5th wheel. However, when it's really hot and you're those AC units along with other appliances,...

  • Can Onan 11,000-Watt Tri Fuel Portable Generator Power 50A 5th Wheel With Two AC Units
    Hey Tyler! Yes, the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR can power a larger 50A 5th wheel like your Solitude. It produces 9,000 running watts on gasoline, which gives you enough capacity to run two AC units along with other normal loads. You will still need to manage your power usage since things like the microwave, water heater, and other high-draw appliances can add up quickly when both AC units are running. I'd especially avoid trying to start several large loads at...

  • Recommended 240V/50A Tri Fuel Portable Generator and Furrion Chill Cube
    Hey Brian, welcome back! For a generator, I recommend the Onan 11,000-Watt Tri Fuel Portable Generator item # CM98MR. The Onan item # CM98MR is a Tri-fuel powered generator that runs on gasoline, propane, or natural gas. It has 50A 14-50R, 30A L14-30R, and 20A GFCI duplex 5-20R AC outlets.

  • How Does The Cummins Onan P11000iTF Paralleling Kit Work?
    Hey Joshua, thanks for reaching out. Yes, that's exactly how the Cummins Onan P11000iTF Paralleling Kit works, and it's a little different from the portable generator parallel kits most people are familiar with. With many smaller inverter generators, the parallel kit itself contains the output receptacle, so you plug your RV or load into the parallel box. That's because the individual generators don't have a receptacle capable of handling the combined output. The Onan P11000iTF generators...

  • Generator Power Output on Natural Gas vs. Gasoline
    Hi Curtis, you can expect about a 20 percent reduction in running power when using natural gas instead of gasoline. This generator is rated for 9,000 running watts and 11,000 peak watts on gasoline. On natural gas, it is rated for 7,200 running watts and 8,800 peak watts. If you choose to run it on propane, it falls in between at 8,100 running watts and 10,000 peak watts. That reduction is normal for tri fuel generators since natural gas has a lower energy content than gasoline. If your...

  • Is the 64 dB Noise Rating for the Onan 11,000-Watt Generator Measured at Full Load?
    Hello Sam, That's a great question. I reached out to Cummins to get some clarification on this for you. They confirmed that the published 64 dB noise rating for the Onan 11,000-Watt Tri Fuel Portable Generator # CM98MR is based on full load. As the electrical load decreases, the generator's engine doesn't have to work as hard, so you can expect it to become quieter during lighter loads. Unfortunately, Cummins does not publish separate decibel ratings at 25%, 50%, and 100% load for this...

  • Is The Onan 11,000-Watt Tri Fuel Portable Generator CM98MR CARB Compliant?
    Hi Perla! Though I may have an option for you, the Onan 11,000-Watt Tri Fuel Portable Generator - Gas, Propane, or Natural Gas - Remote Start # CM98MR is not for sale in California as it isn't CARB compliant, unfortunately. So with that said, the closest CARB compliant option we have is the Champion Dual Fuel Inverter Generators w/ Parallel Kit - 7,000 Running Watts - Electric Start # CH49FR. It's a dual system that needs to be used in parallel to get up to that 7,000 running watts, but...

  • Can Onan Generator part # CM98MR Be Used at Elevation
    Hey Raul, we have just what you are looking for. To use the Onan Generator part # CM98MR at a higher elevation you would just need the high elevation jet kit part # CM65FV. This comes with jets that range from elevations from 2,000 feet to 7,000 feet. What elevation will you be at?

  • How the Remote Start Works on the Cummins Onan P11000iTF Generator
    Hi Carlos, great question. The remote start on the Cummins Onan P11000iTF, part # CM98MR, is really straightforward to use. It comes with a wireless key fob, so once everything is set up, you can start the generator without having to walk over to it. Just make sure the battery is connected, your fuel supply is hooked up and turned on, the fuel selector is set to the fuel you're using, and the main engine switch is in the Remote or Standby position. From there, all you have to do is press...

  • Can the Cummins Onan 11,000W Generator Run Two RV Air Conditioners?
    Yes, the Cummins Onan 11,000 Watt Tri Fuel Generator part # CM98MR is designed to run two RV air conditioners at the same time and has the capacity to handle many dual 15,000 BTU AC setups. On gasoline, it produces 11,000 starting watts and 9,000 running watts, which is more than enough for the running load of two air conditioners and their startup demands in most RV applications. Even when operating on propane or natural gas, the generator still provides substantial output. It is rated...

  • Does the Remote Start Work on All Fuel Types for the Cummins Onan P11000iTF?
    Hi Michelle! Yes, the remote start key fob on the Cummins Onan P11000iTF part # CM98MR will operate the generator whether you're running on gasoline, propane, or natural gas. The only thing to keep in mind is that the generator has to be set up for the fuel you're using before you hit the remote start button. If you're using gasoline, make sure the fuel valve is turned on. If you're using propane or natural gas, the fuel supply needs to be connected and turned on, and you'll need to set...
