I recently bought one of the Boli 3600 generators, and it is relatively quiet, but not as quiet as the little Honda 2000.
On a recent boondocking trip we were parked near several people with Hondas. I ran the Boli in the back of the truck bed which is equipped with a camper cover, and while the generator was running, I left the rear window of the cover open, tailgate up. No need to ever even lift the generator.
Under these circumstances, the Boli was much quieter than the Hondas and with just the back window open, there was no overheating problem.
