We recently purchased a 2008 21 ft front bed Bigfoot
and in the head next to the toilet there is a switch whose function is a mystery to us. All of the research we have done leads us to two possible options (although there could be some other functions that we are not aware of): we think it is either a switch to change the hot water tank to electric mode or to turn on the heater for the holding tanks. Can anyone shed light
on this mystery?
