Sewer Hose Storage
In our RW 305, I put all of my "sewer stuff" in a big plastic square bucket and keep it in one of the outside storage boxes in the rear of the unit on the spare tire rail. One bit of caution on these outside storage boxes--when traveling down the road always put a bungee cord across both of them (i use a black one to make it kind of blend in). If you look closely at the release lever, one good bump (especially in Louisiana), can unlatch the whole project and the box is gone and next the spare tire will rattle it's way off etc. Just some preventatitve safety I do.
