As the I-Ch'ing� says "�it furthers one to have somewhere to go " Thanks to the list I had and I did. My problem with the leak at my water tank turned out to be at the fill neck very small leak that I did not see at first . I used some Silicone Rescue Tape on the fill neck and reattached hose. I do not see any leak under or in the Van so far. now we will have plenty of water for the coming camping season. Thanks a lot to everyone who replied.
