There have been several threads regarding removing the water filter(AKA Water Time Bomb) from inside the trailer. I wanted to share my solution (Flagstaff 21fbrs):
I installed two 1/4" threaded "U" hooks under the trailer, near the edge of the pass-thru floor. Fittings, a hose bib and quick-connects were added to the filter. QC fittings were added to the 4' hose and long supply hose.
The assembly hangs from the hooks when we are parked and setup.
I also moved the water pump closer to the door and added a protective cage made of wire shelving. I can monitor the pump and lines, and also access the valves thru cutouts in the cage.
So far I am happy with the setup.
