What is this tank in my Cloud bathroom?

Newbie Alert! Picked up my first Airstream 3+ weeks ago and can't stop smiling as I look out my front window and see it parked in my driveway.

Sorry if I am repeating any info already here but I searched the forums like crazy to find out what this metal tank is in the bathroom of the trailer. It sits up behind the toilet, below the little cabinet. Is this a fresh water tank exclusively for the bathroom? I have another fresh water tank behind the couch so just was not sure. Thank you guys!

The mystery has been solved but has further deepened! After tearing everything out of the trailer the tank is an AIR TANK! What was the purpose of this huge tank in the bathroom? The toilet was cleared moved to accommodate the tank. Wow.

Well, it's before my time, but I believe the air tanks were used as a way to pressurize the water system without having to use a battery and pump. I'm guessing the trailer has propane lighting as well?

Thank you! I really searched high and low and wasn't sure what the purpose of it was. In removing the bathroom, I can tell at one point the toilet was moved and a new black tank was installed to accommodate this air tank. Yes, the trailer has propane lighting! Thank for your message, now to think of what to do with the 3 foot tall tank! My boys want to build a rocket! They think it looks cool - LOL!
