J,
No "wisdom", just what I do.
As I frequently camp (and then return home) in sub-freezing temps though out the winter, I use the "dry method".
Drain everything, blow air through the lines, and dump a little anti-freeze in the sink and tub traps.
No "fancy" fitting, just a device that allows my air hose to connect to the pressurized water inlet which I suspect you can get it at RV stores.
Takes about a hour which includes dumping the tanks (as long as the dump valves aren't frozen....)
I suspect you will find many others who prefer the "wet method".
Safe travels,
Steve
Me too. We use the RV in the winter so if we break it out for use it's way easier to just load water rather than flushing a bunch of anti freeze out of the system.
