I donít know where ďthe price differenceĒ quoted earlier in the thread came from, but I doubt that itís accurate if applied to the manufacturer.

As far as I know, Onan discontinued the standard 2800 Watt generator and replaced it with the ďnew and improvedĒ inverter design. New Class B motorhomes which usually have these 2800-Watt generators are now showing up with the inverter generator model. I expect the same will happen with the 4,000-Watt size. Once available, I expect the standard will be discontinued.

As cost of lithium batteries and inverter/chargers have become more affordable, itís made going without a generator more feasible. Air conditioning is still a hurdle, but otherwise Iíd have no need for a generator. Onan must know they have to be as competitive as possible, both noise and cost.

Iím looking forward to seeing upcoming 4000i specs. When I spoke with an Onan engineer at RV show I was disappointed the 2800i would not idle or operate at lower RPM under low load, but was told that it would not react fast enough otherwise to start a standard air conditioner. With higher capacity, the 4,000-Watt size may be able to run slower than the 2800i model, which could have advantages for larger RVs.

If I had these interests I think Iíd just buy the Honda portable. Itís quiet, cheap (relatively) and versatile. I keep mine at home to use for heat and refrigeration during power outages but Iíve never needed it for camping.

They had two motorhomes, one with the 2800i and the other with the 4000 generator. They started each and at no load measured the nose using an iPhone app at 20' and 50' from the motorhomes. Then they started the A/Cs (same model on both) and did the same measurements. I suspect the A/C noise affected the results as much as the additional load on the generators.

The Onan QG 2800i was 8-9 dB under the 4000 model. Here is the data:

Standard RV Generator Onan QG 2800i
20 feet (no load) 67 dB 58 dB
20 feet (AC load) 68 dB 59 dB
50 feet (no load) 61 dB 52 dB
50 feet (AC load) 61 dB 53 dB

Insofar as fuel consumption, that comes straight from the Cummins data sheets and I seriously doubt that they are distorting it. I have used their engine data on their diesel marine engines and it was always right.

The cost of fuel isn't my biggest interest, but it is worth something. More important is the ability to dry camp in one spot while running the generator several hours per day to charge up a lithium battery bank and not run below 1/4 full where it will shut off.

And the EFI is also a big plus. Ethanol gasoline doesn't affect modern cars because they have EFI (electronic fuel injection) which totally contains the fuel and doesn't allow any air or moisture inside. So you don't have to add stabilizer or anything else for winter storage.

I believe that the Onan inverter generators will soon take over the RV market from their standard ones.

I looked up my 5.5HGJAB and it says 66db at 10 feet at half load. I love the idea of pure sinewave and fuel injection. but the sound isn't that much different

What's your power plan after that 6K diesel is gone?

So, not that I've kicked the Onan to the curb yet, but gonna start with 6 Battleborns plus all the fixins that go with it, ie hybrid converter thingy (for more technical jargon terminologies, I'd hafta ping Gmthrust).


I've asked my better half for a way to be more silent and still be fully operational in the nature settings of Alaska. I really super duper love the idea of a herd of caribou surrounding our rig....and/or if I told you that waking up in the morning to see an arctic fox playing outside my window is my idea of heaven on earth!

You won't be pa4king anywhere the animals aren't positively indoctrinated, for many generations past, to the value of them walking up to a motorhome.
Cookies, potato peels....

Even yappy little dogs won't stop much more than the most timid bunny.

You're right...so maybe the dream could be reiterated this way: I want to hear them.
