We all want a quiet generator, and a smooth running one also, that uses little fuel. Now, not picking on you, but a few more details. please, and no, I don't have one. What size are you thinking, if you don't know, what are you trying to run with it? Looking for a permanent mount, or a portable? Are you sure the campground(s) you plan on staying in are generator friendly? I'm sure there will be other questions at a later time.
Also, don't get your hope up finding one here. Never seen but one or two come up in over 4 years of being here.
