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).

Thanks for that.  Odd that the dealer wouldn't have known.  Of course now I'm scratching my head as to how water would have pooled in that compartment. It was definitely water and not waste.  Will check it again before I put the trailer to bed for the season.
