I have been reading about your updates with great interest.
I just got a 1988 8V92 40 ft Newell with tag (coach #179)
a couple of weeks ago.
I am learning a lot from the forum.
I previously purchased a readout system From Garnet (See Level II)
for my fifth wheel and was able to read tank levels in increments as small as 3%,
the sensors just stick on to the tanks. Multiple sensors can be
stacked for taller tanks.
They have many different models..
