Finally getting around to posting this after 8 mo.
Had the normal problem with the "dirty" probes in black (mainly) and grey tanks, because of their mounting position on the sloped portion of the tanks at the outlet end. Never were reliable and a total pain.
Went to he SeeLevel system and dual panels, one replacing the original panel in the bath area and added a second panel in the water bay area for convince.
This is a very easy upgrade to the old KIB in tank probes and panel many of us TS owners and many others have. The original panel is replaced using existing wiring to the KIB panel. I added a second panel in the water bay which is a simple wire splice.
Hope this helps...
The added blue/red pex and valves are for this (WaterBoss 700 softener that fit in the forward bay, driver side), which was a great addition too...the wife loves it.
