I have a 2011 3950 that I'm taking on the road for the first time next week. Picked it up last Oct. and can't remember what the young man told me this red switch located under the TV in the kitchen was for. My first quess is the water heater but then I have that on the main control console by the door. I tried the water heater without turning on this switch and it works fine. Is this possibly for the TV booster?
