Tanks for a 69 Caravel.

[mnelson]

I have 3 tanks in the trailer. One black water and one for fresh water. The third one at the back of the trailer is unknown to me. Can anyone help on what the tank is used for?

The third tank might be for grey water (sink and shower). It would not be a factory install since they did not go into production until the early/mid 70-s.

The funny thing is both the kitchen and bath sink drain straight to the outside. Are there any plans showing what the tank might have been used for?
