Keeping black tank healthy

A quick question. I know you generally don't want the black tank to dry out so I put about 5 gallons in after dumping. Sometimes we go 4 months or so before going out again. My question is, about how long before that 5 gallons evaporates and should I be adding more in between trips?

Thanks for in advance for any advice.

Other than expansion and contraction of the air in the tank due to temperature changes there is really no air movement to dry out the tank. Add six or seven gallons if it would give you peace of mind.

Don't forget to add a little RV antifreeze if you are storing in the winter.

Adding a little RV antifreeze is useless and a wast of money. There are very few RV antifreeze brands that, according to labeling, may be diluted and still provide freeze protection.

As I'm sure you know jrstout89, if winterizing you drain the tank before adding antifreeze, common sense.
