This will be our first time dry camping. The 5er has a 5500 watt Onan quiet generator. How "quiet" is this genny? I also have a Yamaha 3000 inverter I can take along. We'll need to run the AC almost constantly. The biggest concern is being as quiet as possible at night. Thanks for the help!
If your question is... Which one is quiet enough to run during "quiet time"? None of them. Not trying to be a downer, just informative. Reading between the lines, that's what it sounds like you're asking.

If you'll be caught up in the heat wave covering much of the U.S. during your upcoming camping, then my sympathies go with you!
You might want to camp where you can run your generator all night so you can get some sleep - there are places where you can do this. Even in normal quiet time campgrounds, if the unusual summer heat keeps up then I suspect more and more folks in parts of the U.S. will begin to ignore nighttime no-generator-rules this summer in order to make it through their camping trips.
Your biggest problem with the 5500 watt Onan may be fuel consumption. If you're real lucky, you may get around 2 and 1/2 hours of runtime per gallon of gasoline on it, but more like 2 hours, as the other poster above mentioned.
We use a green spark plug and Mobil 1 EP synthetic oil in our 4000 watt Onan to drive it's fuel consumption as low as possible and do get at least 2 and 1/2 hours per gallon when running the air conditioning. It's installed well enough and just a bit quieter with these two changes, so as to not be too irritating when running ... especially in the camping spots we usually wind up in.
