Replacing Noisy Onboard Generator In Jayco Grewyhawk With Cummins Onan Quiet Series 4000w
Updated 07/18/2025 | Published 07/17/2025
Question:
I'm replacing a noisy aftermarket generator in my Jayco Greyhawk. Will the Onan QG 4000 be significantly quieter?

Expert Reply:
Yes, the QG 4000w generator # CM42ZR is known for being ultra-quiet, making it a go-to option for national parks and campgrounds.
It's built-in sound-deadening design uses a sealed muffler and vibration isolation. It meets the 60 dB@50 ft standard, so you’ll get more “outdoor coffee and birdsong,” less “lawnmower at the lake.” If you're tired of yelling over your generator, this is your upgrade.
