Tank sizes on 76 Overlander

[overlander76]

Does anyone know the size of the three tanks (water, grey, black) on a 76 overlander 27 foot AS? I think the water is way less than 50 gallons. The other two I have no idea. They don't seem that big (10 or 15?) I can't find this in the service manual anyplace. I was wondering what size container I need to use to empty the holding tank into to and transfer it to the septic tank. (Yuk!) I see those blue transfer tanks with wheels I could use but being a tight wad I was thinking of a poly barrel in the wheel borrow or something? When I get ready to do it I'll be sure to take pictures. ; )

Thank you so much for all your time!

Mine is a 74 Overlander International, I would assume a 76 is the same?

As you were thinking they are small, 20 gallons on the black tank, 10 gallons on the grey and 45 gallons on the fresh water. You definitely won't want to leave home without your blue tank!!
