If that is the inlet, there should be a check valve to keep the water from going back into the hose. I don't have a picture of the check valve, but they are somewhat subtle. (otherwords, they almost look like another fitting or coupling in line)
My plumbing manifold is not near the hose intake. Mine is on the other side of the coach, so your manifold might not be there anyway.
Is this a new to you coach? If so, who knows what a previous owner has done.
I also noted that the cut out I see in your picture looks like there are screw holes on the side. It looks like a cover plate of something was taken out.
