Size of grey water tanks?

[Bodhisatra]

I have a 2006 Forest River Wildcat 29RLBS and all the info I’ve been able to obtain so far is that it has:

43 gallon Fresh Water tank
37 gallon Black tank
74 gallon grey tank

But I’m also told and the panel shows both a grey tank and a “galley” tank. I’m assuming they’ve combined the info from both tanks for the total of 74 gallons. But that doesn’t tell me what size each grey water tank is and they are separate tanks. This info would be helpful in purchasing and installing heating pads. Any assistance would be greatly appreciated.

My guess would be that all the tanks are 37 gallons. The fresh would be 37 plus 6 gallons of water heater; 37 gallons of black; and two times 37 is 74 so I would say your grey tanks are 37 each.
