You can order the tank through American RV Company (talk to Haroon). It is a 75 Gallon made by INCA plastics. Not terribly difficult to install, just undo the existing connections and pull the tank from the driver side compartment. Slide the new one in and hook up the lines (see attached pics). The fill door will get cut in to the side of the coach for the 1 1/4" fill and vent line to attach. I had a local automotive paint store make up a can of aerosol paint to match the exterior color so I could shoot the plastic door, looks factory. I also installed an accumulator tank at the same time which helps with water flow (less pulsating) when running the pump. The only negative with the whole thing is you loose a small amount of space from the drivers side bin (see pics) but that was worth it to me!

BTW, FR fix for the over flow is to add a longer hose and coil it three times on top of the tank before taking it out the bottom. As explained this way the water cannot get to the point of draining by siphon.
Am I missing something here? Why go to the expense of adding another tank or changing the tank? Pick up a couple of plastic 5 gallon water jugs that tent campers use. Dump them, or pump them into your main tank when it gets low.

As for the syphoning problem, I have a short length, 12 to 15 inches, of hose I attach to my fell hose. This slides into the fill pipe but does not screw on. This prevents the main tank from building up pleasure and stops syphoning.

I'm going to attach a T fitting I have right at the point of the vent hose off the tank. This T fitting that would be at the bottom of the letter T, but that would stick up. It that threads and a cap on that part of the T so I'll just keep that cap loose and that would allow a vent to prevent the siphoning affect. If that makes any sense?
