Gurgling at fresh water tank vent when filling

Today when filling the tank, just like normal every other day I go out turn the water on at the hose spicket about a 1/4 of turn.

Normally I can hear the water falling and hitting the tank when it’s really low ( 1/3 of tank) but today it started gurgling sound, I kept going thinking there might have been some air in the hose but it did not stop.

Even when the tank got full, the water started to pour out the vent like normal but the gurgling sound was gone but the water was being forced out to the same sound as the gurgling had made.

I checked all the water lines inside the camper and nothing was leaking. The bottom of the camper has the all season package so it is sealed off so I can visually see the fresh water tank to check it.

Any ideas?

Thank you

Gurgling from the vent when filling isn’t anything to worry about. It’s normal and more common than you think.
