Holding tank thickness?

[Sneakinup]

Does anyone know the approximate thickness of the blackwater and freshwater tanks used in the 70's?

I am thinking about replacing my control panel with a new tank reading device, and the wall thickness can't be more than 3/8". It utilizes an external attachment on the tanks, 2 wires per tank, and a simple installation.

I'm sure someone knows!

The wall thickness is definitely less than 3/8in.
I am guessing 1/8in average.

Thanks! I didn't think it was near 3/8" but I haven't ever removed any of the fittings to get a closer look.

If you are interested, here is a link to the tank sensor that I am looking at. They have ones that read LP gas and battery also, totally eliminating the old circuit board in vintage trailers, and with no invasive procedures needed on the tanks.

FWIW

I got some pricing for the Sensa Tank. It is $130. It comes with foil sensors for attaching to the tanks. Ribbon cables to sending unit, and an RJ-45 jack to run one cable to the panel. That and a simple 12v hook up. They also have a model to hook to the LP gas.

Way cool!
Just what the doctor ordered for replumbing and/or retrofit tanks.
