I normally go two weeks on a single dump.. With one or two exceptions every year.
NOTE. Don't know how long I can go. but I full time using my Membership camping privlidges. In the summer I stay 2 weeks where I am now fully hooked up and 2 weeks in another membership park where I only hook up electric. The reason is the water there is not as good as it is here so I only use water from this park.
In the winter.. Same thing only instead of 2 weeks out it's one in a government run park.
The exception.
Last fall I left here on halloween-een (The day before halloween) and the 80 gallons in my fresh tank lasted till Thanksgiving AM I'm serious about that. I ran out as I finished doing dishes
The first 80 gallons of South Carolina water lasted a week.. Why? More frequent flushing (Changing water sources will do that to ya) so I took an extra dump or two on the old black tank too.
IF 80 gallons runs dry.. it's time to dump the waste tanks. Even if it's only been 6 days.
