Steve,Great info! got any pictures or diagrams? I am considering the mock up. I think you're right, it is the only way to make sure it will fit. I'm seeing all kinds of diagrams on line. Some have a loop and some do not. One guy claims he had a tank made by ronco in which he had the inlet to the tank installed low with an internal stand pipe. This would take the place of the loop. He put the tank directly behind the head and ended up with very short hose runs. I really like this design. It seems simple, eliminates all the hose and vented loop in the head compartment. It looks much cleaner, allows for a gravity drain and gets the pump-out fitting on the side deck. The one on the boat currently was installed right next the the mast and is labeled "water" and whoever installed it hacked it and caused spider web cracks in the gel coat that travel several feet. My biggest concern with this design is whether or not I can get a tank to fit. I'd probably have to cut out the base of the storage compartment and commandeer that space. So, this is starting to sound like more of a project than I want it to be... I could use the same location as the existing bladder but, then these is no real way to empty the tank without another pump that I can think of. Then the cost goes up and the system becomes way more complex... Here is a diagram of what I was thinking of...http://sdrv.ms/18Gs2FG

Date: Tue, 22 Oct 2013 08:33:31 -0400 My original tank was made by Kracor. I just went through this exercise last season. The kracor tank for my boat is still available from Kracor but they wanted $700 plus shipping .. and shipping to Canada would have been over $100. Ok. Next option? I had removed the old stainless holding tank (some PO had replaced the original kracor with SS) because it was leaking when I got the boat. Gross. First job I did on the new boat. Gross. Anyway, plastic-mart, yup .. I found a 20 gallon holding tank that fit in the bow perfectly!Total broke down like this:Order Items ---------------------------Qty: 1 - �20 Gallon RV Waste�Holding�Tank - (S-H2020-B (bow)) Price Each: $200.99 Build a Tank - I will submit a technical drawing with fitting locations Qty: 1 - �Holding�Tank Pump-out Kit - (DT-30) Price Each: $47.99 ---------------------------2 Items Subtotal: $248.98 Tax: $24.30Shipping: $54.74 Total: $328.02 The $700 price for the kracor was just the tank, no fittings etc. I'm very happy with the plastic-mart tank and the service was excellent. I took measurements from several of the online tanks that I thought would fit and then mocked up the tanks with cardboard and then checked for fit on the boat. I'm glad I did this it worked out perfectly. Do consider mocking up a cardboard tank if you have ANY doubt about fit. Good luck, it's a dirty job.
