Hi Veteran,
H'mm, Sunline 130 bobcat camper, that is not a common Sunline model unless it is one of the really old 60/70's camper and possibly a porotype. What year is your camper and where did you see the the Sunline brand on it?
By chance, is this a Skyline 130 bobcat camper? If so, Skyline is a different camper then Sunline.
That said, Sunline used the KIB tank monitor panel on the newer campers, newer meaning the last new one made was a 2007. This system used probes inside the tank and a remote monitor panel.
The tank panel

The probes

The tank panel works well for the probe type technology. You get, empty, 1/3 fill, 2/3 full and full indication.
Sea Level (not used in Sunlines but an upgrade) makes different technology and gives a finer resolution in percent of water in the tank. The sensor are mounted outside the tank and do not give false readings when paper or curd gets stuck across them like the probe type has. The Sea level does cost a lot more, but works better.
We have been using the KIB probe type since 2003. Keeping the tanks clean and understanding your tank water usage in days, make these system work OK. I was conserving the Sea Level system, but there was always some else that was needed more then upgrading the tank levels.
Hope this helps
John
