Thanks, Sharon and Captain Jack!
I may not be phrasing my question right. As Lefty mentioned, in order to "fill" the fresh water tank, I have to hold the male garden hose end to the male fill hose end... and that just doesn't sound like a standard operating procedure to fill a fresh water tank. In fact, I am not convinced that this fill hose is a "gravity" type. Spilt water would travel down the fill hose and drop inside the compartment. I would suspect that the hose is made for a connection of some kind... but what kind?
Sharon, I've been looking at that fill adapter, but the tube on it is 5/8"... the fill hose on the 2501 is 5/8" at the most... so I don't think it will fit.
Captain Skip, Is your fill hose also terminated in a male threaded connector? how do you connect the fresh water source to your fill hose?
Thanks Again! Trip is in two days... so I need to start the sanitization process tonight.
