The Cummins Onan 5.5kw is one of the better air-cooled gasoline RV generator on the market and packs a lot of power in a compact package while still offering superior noise reduction and fuel efficiency.

Typical applications include Class A and C motorhomes with single or dual air conditioning, fifth wheels, travel trailers, sport utility trailers, horse trailers and industrial vehicles.

Watch Your Fuel Quality And Keep Your Injectors Clean
I have this generator on my 2013 Thor Challenger 37FT. First, ensure you only use quality, name brand gas. Costco gas is also an option as they have strong quality control. Secondly, use a quality fuel injectors cleaner in your fuel tank on a routine basis. These two marginally higher cost practices, will pay off in the long run. The same fuel injector additive for your gas engine will also help keep your generator carb and engine running smoother. I have been doing this for several decades and... more

No Problems
I read that many are having problems with the Onan 5500 watt gen. We have owned ours for 5 years without a hitch. My dealer gave me a tip years ago how to maintain an Onan and get years of life from it. First of all, our fuels or gasoline's being processed in the USA are the poorest quality in years. It's trash and the generators get the bad rap. I pour in a can of Sea Foam per 20 gallons and put a heavy load on it for 30 minutes. Everything ,roof air, electric hot water heat, etc. This opens... more

Takes Forever To Start & Won't Stay Running
I have one in my new toy hauler and its been nothing but trouble. I have to start it at least 15 or 20 times before it will stay running and then when i turn on more than the TV the whole generator dies. It only has 45 hours on it and they have been the worst hours of camping ever, I've taken it to a Cummins service facility twice and both times they say its good and fixed , then i have the same problems again. I heard it was one of the best but I'm not seeing it!!!!

Very Poor Prodcut
I have a Coachman with an Onan generator. Only got two hundred hours on it. I had to repair a broken rocker arm and now it has a serious oil leak. I've never had such an unreliable machine. Cummins should be embarrassed by the product they produce. Maybe that is why they won't list their prices on the internet.

I'm An Rv Tech
This is a very well built generator. The biggest problem I see is the carb varnishing but it is not the generator's fault! You need to run these things not let them sit for six months or longer! Also as with any small engine use fresh fuel, once a year or 150 hours maybe change the oil, Methanol can lead to more carbon build up and since the throttle doesn't change RPM much this will cause more build up, you can't rev it like your old Chevy or Ford to blow out the carbon. A can of 4C from Onan... more
Pros: Durable, Easy To Use, Quiet, I'd Buy It Again
Cons: Heavy, Expensive

Cummins Has Problems
I had mine repaired four times for the same problem at Cummins service centers. The service personnel have always been nice and helpful, but the design of the generator drive unit fails regularly. If you have a problem be ready to pay 14-17 hundred.
Pros: Features
Cons: Unreliable, Durability, Expensive
