As above, I have a different model, 05 Kountry Star. Mine has 600W inverter that operates the front receptiveness behind the driver's seat, plus TV and entertainment center. My inverter is located in the Storage bay on the passenger side, behind the read wheels. There is an on/off/remote switch on the inverter. If you choose remote, my coach has a small panel on the bedroom wall on the left as you enter. It is just a small push button with a light to let you know it is on.
