Black tank
Just curious. What is the longest that some of you have left your black tank go without/before dumping it? Dusty

the black tank is a holding tank only. the waste does not decay in a black like it does in a septic tank. do not get the two mixed up. BECAUSE if you do, you will have a 25 gallon brick and impossible to drain. and one other thing to know is do not ever, ever leave your black tank valve open when not dumping
