I have a cougar 2019 5th wheel with incorrect levels on my in-comand system.
One time my #1 gray tank showed 1/2 full. And it was full. I could hear bubbling in the shower drain.
Fresh water, filling it up and it was only showing 2/3 full. Water was coming out the fill nozzle.
Black tank. Your right, I don't take that chance and dump at 1/2 . With a good rinse.
I do not like running back to the dealer for this and every little problem. I feel it should be an easy fix for the owner.
I am thinking of filling my tanks with a measured amount of tank capacity water and see what it shows on the read out.
Any ideas?
