Question Fresh Water Overflow

Hi All, WRT to my 2015 Greyhawk 31DS, I have two questions about the fresh water tank.

1. Where is the overflow located; and

2. My manual says that it can be "gravity fed" to fill it. Is this possible and if so where is the filling port?

Thanks in advance for the help.

1. I believe there is just an over flow hose that sits in your tank. That's what I believe happened when I overfilled my tank a little, just spilled out onto the driveway.
2. Mine has a "Country Fill" option on the switches inside my storage cabinet. Connect small hose to regular inlet and the water was syphoned into tank. I didn't here the pump come on so was not sure on the whole process. I only needed al ittle water to get me by.
I have a 2013 Greyhawk FS31.

1. If you hook up to city water and let it run on the "City Fill" setting for 15 minutes or so you'll very quickly learn where the overflow is located . . . ;-)

- On our unit the overflow is 3 small white tubes (bigger than pex tubes but smaller than garden hose size) that hang down beside the fresh water tank under the vehicle.

2. As far as I know there is only one water connection outlet or port for fresh water. I've never heard of gravity feed filling. I can't see how that would work as there is an inline valve that opens under pressure to allow water to flow into the tank that gravity fed water likely wouldn't be able to open (ie. not enough pressure). The "country fill" feature allows you to fill the tanks by pumping still water into the tank utilizing the onboard water pump.
