In my case the bumper storage was a bit yucky from the prior owner. And I was worried about rust.
So I made one of the fence post/rain gutter units and now I easily store 2x10' hoses plus a shrinking garden hose with nozzle (dedicated for cleaning the waste hoses and gear). I did buy an extra 5' hose and it now lives in the bumper.
My "extra" use for the in-bumper storage is when we stop somewhere for the dogs to do business and there isn't a trash can around for the resulting bag of waste. It goes into the bumper until our next appropriate stop.
