Hello,
 Has anyone come up with a better water level sensor for the westy
holding tank? I'm looking for something that will tell me how many
gallons I have, not just that its "almost full", "in-between", or
"empty". I'm thinking either a float-type resistance sender, like a fuel
sender, or maybe a capacitance probe. It'll interface with a basic stamp
and LCD screen, to take the place of the LED panel that's there now.

While I'm working on that, I'm going to make a water level alarm that
beeps outside the van when the water tank is full, so I can stop filling
before filling it all the way up and having it leak out the filler tube.
Anybody done that?

Cheers,
 Jeff
