What is this hose from?

Can anyone tell me what this hose poking out under the front of the trailer (2024 320 CS-S) leads to?

I was moving the trailer after blowing out the lines in preparation for winterizing and a fair bit of water ran out from the hose.  I asked my dealer about it and they didn't know, but, thought it might be a drain hose for the AC.   The trouble is, other than to make sure it worked, I haven't run the AC since I picked the trailer up in May.   If there had been condensate pooled anywhere, wouldn't it have drained out during my summer camping trips?  I am concerned that if any more water pools wherever it was that the hose leads to there will be damage when things freeze up over the winter.

Thanks.

Hi,  

It's a vent for the cassette toilet tank.  Everyone who has a cassetter toilet has it.  Pull out the gray tank and you will see a vent hole in the bottom of the white  tank compartment,  which is for hose you circled.  It lines up with a vent on the bottom of the gray tank.  When the tank is pushed in, the vent on the bottom opens up (spring loaded).  



When I had my '21 320, the AC condensation drain was on the rear passenger side, almost near the stablizer (actually the same place in my 360).
