Roadtrek Dimp Hose

Mine is still the original hose, it’s about 7 years old. It had a pinhole leak once at about 2 feet from the end of the hose. I just cut it short and have been leak free for years. The hose is stored in an enclosed compartment and should not be exposed to salty road conditions, I think the reason that many reports of hose leaking is that the hose enclosure is small/ cramped for the length of the hose and hose is overly twisted in that enclosed space once all stored, the rubber just stretches and weakens overtime from the extreme bends thus resulting in leaks or rupture.
