My inclination was to never have a completely dry tank. Just want to know what seasoned rv'ers do.
Being a "seasoned RVr" doesn't necessarily mean they're doing it right but
can mean they're just repeating the same mistake over and over again. :R Once you've serviced your grey and black water tanks every manufacturer will recommend adding tank chems, along with a few gallons of fresh water (10% of the capacity of the tank being reasonable) in order to control odour and prevent the formation of pyramids of hard residue that will
always remain despite how thoroughly you
think you've "cleaned" your tanks. ;)
