Empty black tank when TT is parked
I only de-winterized the TT about 1 month ago as we were still getting below zero at night up until that time. We have not taken it out yet either, just waiting for bug season to finish first!
Anyway, on our last trip the black tank was empty. I noticed after de-wintersizing that the TT began to smell inside, so I put some water in the black tank and a container of the orange treatment. Still there was a smell so I dumped in some more water and a 1/4 cup of bleach. The smell is now gone.
Am I correct in thinking that the black tank should never be dry unless parked for the winter?
