In my coach the drinking water tank is 100 gallons and it looks like a bed mattress. It is sandwiched between the top floor and a sub-floor. On mine it would not require any padding since it has a solid floor all the way for support. But I am not sure about the Tour Master as to how the water tank is supported. If it is just supported on certain pivot points, the rubber padding might be a good idea
