Your Airstream has the old pressurized system.
That went out many years ago, as being not very practical.
Everything today is a demand system.
You can change the tank to plastic, add 2 check valves, add a water pump, and it's done.
Steel tanks, of course will rust (not good to drink), and once they leak, they are done.
