Larger fresh water tank ?

We also have found 4 aquatainers are the way to go. They are bpa free. Go to Home Depot and buy 1/2" clear vinyl hose. It almost fits up inside the spout in the jugs without leaking--still working that part out--I just wrap my hand around the hose to spout connection to seal it and refill our trailer fresh water tank as needed.

The extra capacity has nt caused any problem with holding tank capacity, but you will need to watch yours. I have found it easy to refill by setting the jug on the bedside of my truck parked a couple feet away, connect the clear hose and refill.
