Fresh water fill question
So I'm trying to figure out for the first time how to actually fill my fresh water tank. On my last RV, it was a simple matter of turning a valve while I was connected to "city" water. On my Sunseeker, there's a separate opening on the passenger side of my rig supposedly for this purpose...however it's not a threaded opening, it's just an opening with a cover and when I stick a hose in there, the water just comes back out. It seems like I would have to use a funnel and do this verrrrry slowly. Why on earth would they design this like this, or am I just missing something?
