[C320-list] Waste Tank Liquid Level Measuring

[resloat]

When I got my C320 in 2002 the dealer upselling involved a dealer installed 
holding tank alarm that goes on when 3/4 full.  A good investment for less 
than $75.

I have an electronic Stanley stud finding device that will find liquid 
levels in plastic tanks.  It is not advertised to do this, but it works.  I 
tested it on my plastic holding tank and it shows the liquid level.  Tapping 
on the tank with a hammer or wrench works.  There are very subtle 
diffenences in the sound when you tap the tank above and below the liquid 
level.

An alarm is best.
