I use those quick connects too between the hose and the trailer connection. Just one caution though, based on what I found today when doing some general maintenance ..... when you attach the male end of the quick-connect hardware to the trailer it hides the little screen strainer that is supposed to stop miscellaneous particles from getting into the system. When I happened to remove my quick-connect today I found the screen to be quite dirty. Just a reminder. I may decide to remove that screen and use one at the other end of the hose that is easier to see and clean. The fewer screens, the better the water pressure.
