I installed an interior switch for the hot water heater on my 2010 Georgetown 373. It was fairly easy to do since the water heater is located in the basement area directly below the kitchen. The water heater has a small electric box attached to it which provides a place to connect a remote switch using #14 Romex wire. At the kitchen end, I installed a new electrical box next to an existing outlet for the switch. Use a 20 amp switch, not the more common 15 amp light switch. The switch I installed is not lighted, but it is easy to tell if the water heater is on or off by the switch position. The original outside switch on the hot water hot water heater is left in the on position all the time.
I don't know why the factory did not wire an interior switch for the water heater (probably to save money...). It is necessary to be able to easily turn off the water heater electric element when managing the load at a 30 amp campsite, or if you don't need it when running the generator.
Disconnect power before starting any work. If you are not sure how to do this job, get assistance from someone knowledgeable on the subject. Be sure to secure the Romex using wire ties, and use electrical tape to keep the wire nuts from coming off due to vehicle vibration. Total project cost was about $25.
