This unique flat 30 gallon fresh water tank is only 6" thick. It fits many Airstream trailers from 1968-1971. Typically installed under the front pull out gaucho.

Dimensions are 53" x 24" x 6"

It has a 1-1/2" boss for the gravity fill connection. The boss projects at an angle to allow a straighter connection to the inlet on your trailer wall. You will need to use a clear vinyl hose and hose clamp for that connection. Next to the boss is a 3/8" FPT fitting for the vent hose connection. On the side of the tank is a 1/2" FPT fitting for the output to the pump.
