A Yamaha?A permenet unit would not be in my budget. I'm down to 2 generators. It will be either a Generac 5,500 watt unit sold at Lowes or a Ridgid 5,700 watt unit that Home depot has. They are within $50.00 of one another. The Ridgid has a Yamaha engine seems like a little better set up. This unit also get better fuel consumption. so this may be the one I will get.
I have read the reviews in this price range they all seem to be the same. In my case I am concerned about heat and refrigeration.
The generator came with a fuel shut off. I may add a fuel filter at some point.
