'74 tanks

[bwaysteve]

Did any of the 74s have dual tanks or was this later?

I think the 75's were the first, but that's just what I remember hearing.

We owned a 1974 Sovereign, manufactured in Oct 1973. It had gray water, black water, and fresh water tanks. It was a center bath as well.

I think all '74s and a very few '73s had grey water tanks.
Obviously so have every thing since/after.
