How do you know if the holding tanks are full without a monitor? Do you just wait until it squirts out the vent? I couldn't find anything in the owners
manual.
I have a feeling there is no solution until I get a monitor installed, but wondered if anyone has an interim solution to avoid a social malfunction.
