I know this seems silly but I can't find the switch on my "new to me" trailer. There is no monitor panel that I can find. The pump works (I hot-wired it). The wiring runs up in behind the furnace
. The hotwater tank switch is prominent on the face of cabinet. This is not my first, second or third trailer but it certainly has me baffled. It's a 2002 Bigfoot
17.5G 1500. I've looked in all the normal (and not so normal places). Help!
