Please oh please, spend the extra couple dollars on a good quiet Honda or Yamaha genny...
I'm just back from Chicagoland speedway, dry camping in the infield. If I see another of those non-enclosed red noisemakers, I'll just shoot it! Or cut the fuel line. Last year, our next door nieghbor had a champion, a big one, and seemed to think he needed to run it 24/7... :(
Just a for instance... Friday morning, I'm sitting under my awning. My 8000 watt Onan Quiet diesel is going full bore, buth a/c's running. A Bounder next to me, same same.
Guess what? The only motor I could hear was a 3500 red open champion, 200 feet away!
A guy we ended up spending a lot of time with had something called a "kipor digital sinemaster" I think? it was around 4000 watts, and fully envlosed, looked like a chinese copy of a yamaha. He swore by it, and it ran non stop for 4 days, and is very quiet.
