Steve,
I''m in the process of installing a holding tank system in my boat. There are couple of URLs you might hava a look at. The first is Peggie Hall''s article on marine sanitation systems. She''s a consultant in this business and a real expert: www.boatsafe.com/nauticalknowhow/phall.htm
She has a very high opinion of SeaLand, particularly their new sanitation hose. She pointed out to me however,that there are other polyethelene tank manufacturers of equal quality (and wall thickness) with much larger tank selections. Here is the URL for one: www.ronco-plastics.com
