I use the Honda 2K for my Class C rather than the Onan 4K because of noise and gas consumption.I use the Onan only for air conditioning other than the weekly run.
The Honda 2K will run everything in my motorhome or travel trailer except the air and is much more of a gas saver than the Onan,and did I say quieter,much much quieter!Use the 3-2 adapter and there is know need for extension cords.
The Honda generator last for thousands of hours and much more trouble free than the Onan.I wish they had installed a Honda 3K instead of an Onan.Quieter and much more trouble free than the Onan's.I wouldn't trade my Honda 3K for two Onans.
