I have spent the last few hours packing and getting ready to go. Before I arrive i NY I thought I would have an endless supply of water but no dumping options so my priority was op add as little stuff to the black tank as possible. I knew I would be here for two to four weeks and if I filled up the black tank I wound be in trouble. This was unique situation (at least for me) and in the past I never came close to filling the black 1/2 way so I had no way of knowing how quickly the fresh water would add to the tank level. One factor that complicates things is the area in LI where I am staying has not dump opportunities. I now realize that my effort in tring not to add any extra material to the tank by flushing with a minimum amount of water has made the situation worst. I learned my lesson.
