Sewer Hose Cleaning and Storing

Since I store the hose under my bumper, I found a great use for the for the bumper storage area that was designed for a hose. I found small canvas tool bags at Lowes. I hook them together in a chain and push them into the bumper. They carry seldom used items such as nuts, bolts, screws, spare wiring, caulk scrappers, rarely used tools, etc. On the chain I have also included a sven saw and a spare extension cord.

I just cannot understand the reason to use clean, dry storage to hold a wet dirty hose.
