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.
