189 gallons of water would weigh about 1890 lbs which would need a strong support structure that would be difficult to achieve in a below chassis hanging tank.

Dutch is right, our holding tanks are in a bay and are all stainless steel. Our fuel tank holds 230 gallons of diesel and the DEF tank holds 16 gallons.

The 'one' holding tank would not work for small applications.

Mr Mark's motorhome is WAY out of the standard Class A. I do not even put his motorhome in this Class A type forum. His systems are not even close to Standard Class A systems and features. As to Gray and Black plumbing, the comments are all way off. The ONLY reason a Gray sink appliance would be routed to the Black tank is- THE FLOOR PLAN INHIBITS THE ROUTING OF THE DRAIN PIPES TO THE GRAY TANK. There is NO rule or law that states ONLY gray can go to gray and not to a black tank. This is especially true of Triple E motorhomes. OEM's will route all gray to the gray tank if the floor plan will allow it. They do NOT do it as a convenience factor to get more water into the black tank. If you feel you need more water to a black tank, just use MORE water in the bowl when using it or flush longer. Doug
