Well, that's called me thinking outloud
I have not tried it yet. I'm still in the planing phase of my re-plumb job.
My thinking is that I will just have a valve from the cold water line connected to the fresh water tank input. When the trailer is connected to the standard city inlet and I turn the fill valve on, water would just fill the tank until it hits the vent tube and overflows.
If I add a check valve then water can only enter the tank through the fill line.
Just an idea. Not sure how/if it will work.
If I can find a cool external water fill for the trailer, I'd probably add it. But I'm still a ways off from that
