Keep in mind it also depends on where you will be using it, engines loose power at altitude, so if you will plan on using air conditioning at high elevations you need a larger one. My Onan 4,000 will power my air conditioner and microwave oven at the same time with no problem here in Louisiana, but when I tried running them both at 7,000+ ft elevations last August in Wyoming the engine would bog down.
How modern is your Onan generator model?
The Onan in our 2005 Itasca Class C has a convenient knob right on it to turn and set to the altitude it's going to be used at. It supposedly will run much better at high altitudes if you remember to set this knob to the altitude you want to run it at.
Some RV owners may not be aware that their Onan generators have this easy adjustment to make them run stronger and smoother at high altitudes.
