Hello,

I buy Minnie Winnie 31k - 2014 and is my first winter with it.
I made a special use and I want to use it this winter.

So I tought to use windshield water (-40 celsuis) to put in my fresh water tank (50% windshield washer and 50% fresh water).
I only wash dishes and flush the toilet with this water.

But I don't know how to put special liquid on the fresh water fill...
Usually when I only put fresh water, I plug watering on the holl, open water and it fill automatically.
But now, I when to put special liquid on gallon on this. How I can do that !?!

Thanks !

Vodka would be better. But I'd use nothing but the prefered RV antifreeze solution. I would think that alcohol used in windshield washer solution is not good for your innards, or your motorhome's fresh water tank.

and there is a special pump for putting the RV antifreeze into the tank, and some have modified their water pump to do it there.
