After 5 years of regular use with my original Camco RhinoFLEX sewer hose, I decided to proactively get another one and retire the OG to the inside of the bumper to keep as an emergency use hose. Did I consider purchasing other brands and hoses to save a few $$$? Yes I did. Then I thought about never having to clean up a stinky black tank mess and promptly bought another one. If it ain't broke - or hasn't broke after five years of use - then don't fix it, and by that I mean don't overthink it. RhinoFLEX FTW.
