In place of RV antifreeze in the traps you can use windshield washer fluid. It is generally cheaper and you still get protection down to -20. If you are using RV antifreeze in the lines, you are already putting some in the traps. Just saying.

I thought that mold could grow any where it is damp not just in standing water. If there is standing water in the tank, can't the mold grow on the sides and top of the tank?

I don't use RV antifreeze in the lines, I blow the water out.

Just MY opinion, but no, mold cannot grow on the top and sides of the water tank just because there's a little bit of water in the bottom of the tank.  Besides the fact the sides and top wouldn't be damp, plus there's no food source.

Again.. Just my opinion and experience.. I am NO expert on mold.

And thid:

WHAT DOES MOLD EAT?
Mold cannot produce their own food, thus they are parasitic in nature. Molds get food by absorbing minerals, sugars and water from the plants, soil, animals or decaying matter upon which they live.
 

This sounds good and logical but in reality, I have a semi-opaque jug of boiled water I keep on the counter for the dogs (elderly, finicky stomachs) and I have to wash it out periodically because the top and sides (above the water line) get slimy. I don't know what it is but something that I don't want to consume is growing there.

As I said, I am certainly not an expert, or even close, on mold; but, I don't believe boiling water does anything but kill whatever is alive in the water. I don't believe it removes any "food for mold" in the water.  Also, a half or more filled jug isn't the same environment as a closed 40+ gallon tank with a few cups of water left in it that is in an RV parked in one spot over the winter.

But I certainly could be wrong.
