All the tank compartments ducting I have seen don't have return line.
They are design to pump warm air down and let it go "to the woods" via holes around dump valves and other.
What temperatures we are talking about?
I had exposed tanks under my motorhome and camped in 20'F and the tank never froze. Dirty water has lower freezing temp and motorhome keeps warm air bubble all around.
So unless you are in real cold with winds, I think dumping some antifreeze into tanks is all it would take.
