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 . ...
Generally. "Heated Tanks" means that there is a heat vent on the furnace system in the wet bay.
Optionally, it means there is some kind of aux heater (Usually an electric tape on taped to the bottom of the tanks) but frankly.. I like the air duct method better. .HERE is why.
Tanks are not the only thing in the bay, There are pipes (Which survive freezing rather well) and fittings (Which do not).
