Hello VAC list! I've been lurking and learning for a while...I've found a trailer, 1972, 27' International Ambassador. It has no gray water tank. 1. Has anyone put one in this model? 2. What type of tank, where to locate it, etc. or can you reccommend someone in the Seattle area to do this type of work? Thank you in advance...I know someone, or two of you have a thought on this subject! Judy White
