Quieter- A side by side comparison showed that the 2800i is about 8 DB quieter. That is significant and important to me.
Less fuel consumption- Onan's data shows that the 2800i uses half the fuel as the 4000 at mid load, ie enough to power an 80A converter. which will be my primary use for the generator.
EFI injection which means no ethanol problems during our winter storage season.
I plan to use the generator mostly to recharge batteries while dry camping. I rarely will use it to power the AC. Onan says the 2800i will start and run a 13,500 btu A/C but the Axis I have on order comes with a 15,000 btu one. If it won't start the bigger A/C then I can add a hard start capacitor. Even at this heavier load (about 1,800 watts) the 2800i uses 2/3 of the fuel as the 4000i.
Some have said that I may lose resale value with the smaller albeit more sophisticated generator. Maybe I will just keep the 4000 so if someone really wants more power it should be easy to swap it back.
What do you guys think. Am I missing something.

What are you trying to compare? Standard 4K generator to 2.8K inverter generator? 2.8K inverter generator to 4K inverter generator?
If you want to replace your standard 4K generator with a new inverter generator there is ZERO reason to consider the 2.8K, get the 4K. Due to the way inverter generators work, especially with an "ECO" mode, at the same load the 4K will only consume a miniscule more amount of fuel and will probably be as quiet, if not quieter than the 2.8K generator since it is not working as hard. Plus you maintain the full generator capacity for the MH.
