I would go with the Honda. I have a made in China unit at 2200 watts that runs my window unit. At 8 to 9hrs running time it consumes to muich gas, almost 4 gallons and if u do the math over 24 hrs running u could get a cheap motel room since gas is so high now. IMHO. So with a Honda 2000, and the 6 gallon gas tank attachment, u can get 3 days run time on a tank according to a friend of mine that has that set up. Now he only is running a 5000 btu unit hvac airconditioner, if u run more stuff, gas consumption goes up.
