2015 Columbus 320RS holding tanks

[cjump]

We have 2 indicated lights for black water and 3 indicater lights for grey water. However, there are only three levers outside to dump, one for black water and two for grey water. What are the two other tanks for and how do you dump them?

I also have a 320 with the same panel. I was told at the pdi that it is a generic panel and that yes there are three tanks and to disregard the other panel lights.

Same here, its the same one used in toy haulers and just disregard those sensors.

It is just a panel for more than one type of fifth wheel. Ignore the extra lights.

There are only 5 buttons that read levels. It should read Battery,Fresh water, Black, Grey #1, Grey#2

Thank you all. We'll just ignore the two extra lights. Ours does have 7 total indicator lights with 5 for holding tanks.

Mine also has seven, two blacks, three grey, battery and water tank. Two of them don't do much.
