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!
