So our Class C has the Onan 4K outside and we're now talking about a 3500 watt portable.
The Onan is fine. It's reliable, doesn't use a ton of gas and pulls from the tank. And even tho it's 64 db rating is "Park Ranger Approved", its just too loud by today's standards.
I'm really having trouble justifying buying another 3500 watt genset, when the Onan is fine. But the darned thing is just too loud -- outside of the RV -- these days to be considered a Good Neighboor.
If I already had the Honda's, there's no way I'd consider adding the Onan.
