Have to agree with above post regarding the Generator Supercenter. Never, Never Never do business with them. They will talk a good game and scare you to death about the power system unless you buy their product. Their aftermarket service is bad, you will be waiting weeks if not months for service even under warranty. Briggs, Kohler and Cummings are the way to go for a generator. Generac has had major problems with their units. Lots of cheap Chinese junk parts go into them.
