The Onan 3200 manual shows the watts for various appliances: A/C = 1400 to 2000; fridge = 600 to 1000; TV = 200 to 600 for each TV; microwave = 1000 to 1500; and water heater = 1000 to 1500. You can also expect a 3.5% decrease in power from the generator for every 1,000 feet increase in altitude. In Colorado at 5,000+ feet, our generator outputs 2,640 watts of power. You can see from the figures above that it you were running the A/C, tvs, fridge and water heater, you could easily go over 3,200 watts if you are at sea level. We can run A/C, one tv, water heater and coffee maker without any problem. I did get a heavy duty outdoor extension cord and connect it to the 120v outlet in the outside pedestal, if available, and my DW uses the extension cord for her hair dryer. Best to know the watts and amps of things running. Remember there will be a surge in power when the A/C and other appliances come on.
Well said Sir! And add in a 1% loss for every 10 degrees over 77F the standard test condition). All said, the 3.6 LP is the better choice... Its got 2000W more base load when running the same 13.5 AC. But OP's situation is what it is. The only thing to do is to shed load by selective use of appliances.
(Point of order. The water heater only draws power when it needs to heat water...doesn't work full time...)
