Now all that makes sense. I can see PT using just one panel for cost in manufacturing purposes.....but is it a 70 gal black tank or a 35 gal? PT's web site says 35 gal.
I'll just leave the black tank switch on the panel in the #1 position and forget about it.
The two grey tanks being independent of each other is no big deal, just another valve to open while dumping. I don't think we ever had one fill up and flow into the other while camping anyway.
So I guess they have a factory worker getting crossed up with the wiring if the grey indicator actually shows the galley tank level and vice versa. Not a big deal, but good to know.
Thanks again for the info. I appreciate it.
