Do you use a vented dump tank cap during winter storage?

While shooting the bull at the dump station, a 20 year camping veteran recommended using a vented dump tank cap during storage. I winterize my trailer with RV anti-freeze and store it in my-inlaw's pole barn with cement floor. Does venting the tank gasses help anything? I'd hate for it to leak onto their barn floor.

Um.... NO.

I always keep a couple gallons of "pink stuff" in my black and gray tanks with the valves shut so the liquid will keep the seals wet and from drying out.

I suppose if you wanted to leave the drain open, this would be a useful product. It would let it breathe, and still keep little critters from crawling inside your tanks.
