1970 International waste tank

[catsmith]

My 22 year old daughter picked up a 30' 1970 international this week for her to live in. We do not have the books and have a couple questions. There is only one waste tank on it. I have not hooked up water to it yet to see what flows where. Any help as to what is supposed to go where would be great.

Airstream did not install grey tanks until 1973 so it should only have a tank connected to the toilet. Unless it has been modified. When I tore into our 1970, I found that a previous owner had also plumbed the grey lines into the black tank.

Gray tanks were not installed until the 1974 models.

Thanks. Any idea of the size of the tank?
