You don't need a 50 gallon holding tank unless you plan to spend a lot of time in the Great Lakes. Your L/S are legal on at least 90% of the river systems...so 15-25 gallons should be more than adequate for any overnights in the few places where one is required. Nor would it be necessary to connect both toilets to the tank...put it on the one that gets the least use. Because pumpouts are few and far between on the rivers, I'd also suggest that you look into adding the Raritan "Hold 'n' Treat" system, which would allow you to use the Lectra/San to empty the tank (note that I said "empty," not "dump"). You can see how it works on the Raritan website here: http://www.raritaneng.com/products/waste_treatment/holdntreat.html As you'll see, it's available as either a complete system including the tank or can be retrofitted to an existing tank and Lectra/San. As for a source for the holding tank, Ronco Plastics http://www.ronco-plastics.com is your best source (no relation to the VegoMatic Ronco, btw). They make TOP quality water and waste tanks for a very reasonable price and have more than 400 shapes and size, over 100 of which are non-rectangular...and they install fittings in the sizes and locations specified by the customer when they make the tank. (Ronco supplies 90% of Raritan's tanks, but since Ronco also sells direct, there's no need to pay Raritan's markup). I also highly recommend Raritan water heaters...a bit pricy compared to some, but will last upwards of 20 years vs 5-10 years for many others. Available in 6, 12 and 20 gallons. So instead of a second smaller water heater, I'd go with one 12 or even a 20 gal if it'll fit in the same space as your small one. Just pulling one out and reconnecting the plumbing to a larger one would be a LOT simpler plumbing job than adding a second one, plus you'd never have to worry about which one still has enough hot water for a shower. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/boat_odors/
