Well here is what I did and how mine is set up. Where I attach the hose for city water (also fills up the tank). I have 2 valves where I can set for filling, operating the system and running on city water/winterizing. Beside these valves I have a connection with a cap that you attach your winterize hose. If I leave the valves set up to fill, attach my winterize hose, place same hose in a pail. It sucks up the water. I kept filling the pail until the camper was full. The trailer water pump kept up pretty close to what the garden hose was putting out. So mine works. That's for the help and the suggestions.
