How Long Can You Go Before Emptying Holding Tanks???

Obviously one of the mastery skills of a dry camper. So that is the big question. How long can you hold off between dump station visits???😕 I have found even in an RV park, if I am conservative with my water, I can make the gray water last a week before emptying and sometimes I only have to empty the black water once a month. Of course I always empty all tanks including fresh water and travel dry weight before I hit the road for my yearly snowbird migrations to save on gas.
Some of you however are seasoned boondockers, so you have mastered the skill down to a science better than any of us. So again how long can you make your holding tanks last before it becomes an absolute crisis if you don't visit the dump station or call the honey wagon service. So please bring your feedback here. I of all people want to learn the art of dry camping. Thank You

Wife and myself. We get about a week when black and grey tanks are approaching capacity. Fresh water, about a week as well.

Moved to Upper Michigan in late March of 2011 and lived in my coach solo. The month of April we got +2' of snow so I was pretty much stuck where I had originally parked. Luckily the park had a shower building available where I also washed dishes etc. I went 6 weeks before I dumped after the snow cleared.

Me and my wife can go a week without dumping if we are boondocking using water very conservatively.

We seldom boondock so I keep the gray water drain open all the time and dump the black once a week. It is never full but the odor becomes the determining factor!

Well the first question is how big your tanks are. We have 100 gal of water. After some practice over the years we can manage about 10+ days with no park facility, with bath house we easily get 2+ weeks. But, we dump dish water down the black tank, take Navy showers every other day, don't leave the water run when doing dishes or brushing teeth etc. Its all about management.

We both love our showers in the morning! We can go about 3 days on the gray tank and maybe 5 on the black tank.

Since it is just the wife, me and our labs, we have gone as long as 3 weeks while boon docking during hunting season. We use a lot of paper plates, wet wipes(they worked good in Iraq) and if need be plastic forks and spoons. Once we get to our hunting area, we try not to leave until we really need to. When we travel from our home in Alaska to the 'lower 48', travel with a full tank of water, propane and fuel. The holding tanks are empty for traveling. One of the main reasons for full tanks as that one never knows what will 'go wrong'! While in the 'lower 48' we generally do not worry too much about what is in the tanks as a RV parks is not too far away.

Depends on the weather. Hot weather, beer consumption goes up, and so does black water tank level !
