I was always told to keep the seals "wet", either with water or with antifreeze..... plus I would worry about bugs or road crud getting into the lines? If I had a LOT of RVs to winterize (and they weren't going anywhere), the "open and dry" technique makes sense. Do you leave the black/gray valves open?
Do you also soak your tires, belts, hoses and door seals in antifreeze during the off season?. Or what about the year or two those seals are sitting dry in the packaging or on a warehouse shelf before being installed.
Some old wives tales die harder than others.
