NEW - Generac IQ Series Generators - Ultra Quiet

The market for a generator like this is here and similar venues. Folks who use inverter gennies like Yamaha, Honda, Champion buy them specifically because they make clean electricity and are specifically quiet. How quiet? Why, I bet most owners could tell you the decibel rating of their pride and joy. So why, when targeting a group like campers, would generac not boldly lay out in front what the db ratings are for their product? Not a knock, just a very curious question.
