Hi again folks, so My Class A has "heated waste tanks" as labeled on the waste tank compartment door. I'm trying to figure out how this works. there's no on\off switch that I can find anywhere . ...
Thank you everybody, I see no sign of any type of electrical source of heating in the area so it must be ducted from the furnace somewhere else. Its about near impossible to inspect the area above or behind the tanks . Maybe when this artic polar vortex shenanigan passes I'll be more willing to try and remove things without my fingers freezing off.
