I bought the 1200wC/1500wS 42431 from Champion's recommended fulfillment site to replace the 3rd Honwywell (Northshore replaced the first two, Generac issued a refund on the 3rd one).
All I use it for is battery charging in the camper, and the charger I have now is an old Shauer 10a constant voltage, so I can't comment on the full load capability.
I can say that I've had people bitc...uh, complain about the noise. Once. And this was in the desert, not a campground.
My reply to the complaint was, "A million square miles of open desert, no one else around, I've been here for days, and you come along and decided to park right next to me. So...tough sh**."
My generator has almost 300 hrs on it now. It lives on a shelf on the back of my camper. What with the rubber motor mounts, and the rubber feet, it vibrates the camper a whole LOT less than the HW did, and is almost unnoticable inside the camper.
Outside, different story. It's a LOT louder than the HW, and if you're in a campground (or a desert :D ), and yours is the only gen running - someone is very likely gonna complain.
