Is your camper a motorhome like this one of these? https://www.nrvclub.com/sea-breeze
Is the tank panel you are looking for this one made by KIB Enterprises? This one is listed as discontinued as a complete kit. They do sell some parts for it.
If that is your tank panel, let us know. While we may not be able to find that older model, however, newer KIB models may work with your older sensors. The new Sunline campers have the KIB tank panels, just a newer vintage.
Hope this helps
