Mystery switch, dealer even stumped

Good afternoon folks, we just bought a 15 Vengence 29V toyhauler. There is a switch right above the status panel and pump heater switch panel. This switch is stand alone and right above it. We can not determine what this switch does, any guesses? Thanks!

Tank heater or fuel station?

Some fuel stations have two switches, one inside one out both must be on.

hmmm, I highly suspect the tank heaters. I am really trying to track down some tremendous battery draw. I wonder if the switch is wired backwards, easy enough to tell. Thanks for helping to confirm my suspicions. !

Send an e-mail to Forest River w/ a photo. They answered my mystery. There was a listing of all of the e-mail addresses here a day ago. Try searching for contact info.

Tank heater switch is usually illuminated.

Your high battery draw could be the defroster/climate control (12 volts) in your fridge.

It might be your "step light" as mine is the only thing on that circuit (before I wired my awning LEDS into it).
