Well, it says “Super Quiet” right on the side 😂. It’s what I would call moderately quiet. Not as quiet as the 3500 Predator I had in my previous trailer. That was very quiet. Where I have it mounted with the exhaust facing forward, it will be not be a noise or exhaust issue for my pit, or the neighbor on the other side of me like it would if it was in the gen cabinet on the other side. I wanted to use that large insulated space to store fuel because I don’t want it inside the trailer living space. Generators this size can be staggeringly expensive. This was on sale for less that $2k so a bargain for sure. The 3500 I had was flawless and this had the same good reviews.
