Sewer Hose Support? | The RV Forum Community
2015/3/13· The options were simple, use a support and leave the hose connected, OR, dump and then put your sewer hose away. The support is only needed if you want to leave the hose connected during your stay. Never cared why as I don''t leave a hose connected anyway. I have never owned a hose support. Mar 13, 2015.
