It's hard for me to imagine that this is even thought as a possibility. Running drier vents to route furnace exhaust through the basement of a camper! Yikes!!!!!!!
CO...............can you say DEAD???????
Every Winter ideas like this one (and more) tend pop up on the forum as a creative attempt to get placed on the Darwin Awards list..
It would be amusing except for the mere fact folks are playing with their (and love ones) lives in some vain attempt to save a dollar or two in propane..
If you are this cheap, stay home, using cheapo methods of heating a small box on wheels is not worth it if something goes badly wrong and you wake up DEAD. There is no way I would ever consider reusing the furnace exhaust as a means to keep tanks warm.
Your RV should already be setup with a hot air duct into the freshwater tank bay. Both of my TTs have had one four inch hot air duct from the furnace into the space between the floor and the top of the fresh water tank. Then a "vent" in the floor of this space on the opposite side of the tank (my current TT that vent is under my kitchen sink cabinet)..
