Question about Forest River Forester - fresh water valve

My Sunseeker is the red-headed little sister of your Forester. It does not have any valve in the fresh water fill. But the fill tube has an upward bend between the fill opening and the tank. I could modify it. But instead, I have a 30 inch piece of water hose that I attach to the end of the hose I'm using to fill the tank. I feed the short hose most of the way into the fill tube. Works like a charm.

If someone tells you you have a plugged vent, that is not it.
