Anyone who needs a quiet, powerful and reliable generator should be taking a look at this Westinghouse WH6500E.  This is one of the quietest generators on the market, and is ideal for camping RVing and even if you have noise restrictions in your neighborhood for power outage coverage.

If you need an inexpensive, powerful, commercial grade generator that provides clean output that is electronics safe then the Lifan LF8500IEPL should be on your list.  There are a number of nice features included in a relatively low price for an 8500 W generator.
