1966 Overlander-Gray and Black Tank Questions

[Millsla2]

Question for the Forum...I have removed the rear Black tank and pan and need some advice...

1. do I replace the Black tank with 2 tanks: a Black and Gray?
2. Or do I replace the Black tank with a Gray tank and use a composting toilet? 3. What size tanks do I need (dimensions)?
4. Do I need to have the tank pan refabricated as it was rusted through?

I can't move forward with my restoration until I get the tanks and plumbing competed...thanks in advance for your advice.

Only you an answer those questions for you. In my Tradewind I added a gray tank and kept the black tank, well a black tank.



What I would recommend is adding the biggest gray that you can fit. Size will depend on how big of a space you have open in the frame. You will need to measure it and use your judgement.

If you're planning to keep the original shower unit, there's a little more work that needs to be done due to the 4" frame, you can search the forums for those that have done it in the past. The 1966 Overlander International is a great trailer (own one) and has some of the best looking cabinets of any year made.

Post a few pics, would love to see it.

Enjoy,

Not 100% sure I am following your question but.... In the old units the black and grey waste all went into the black so the black tank is already plumed for grey. As long as you are not using the toilet the black tank is already effectively a grey tank. Hope this helps.

I like to remove the black tank and replace it with the biggest gray tank I can find, usually around 35 gal.. Like the porta-potti "curve" for toilet, much cheaper than a composter. Shower plumbing can be tricky (if you keep it), I went in the side of the tank
on one project with no troubles or leaks, sinks are usually easy, don't forget that code and good practice now allow vent valves as opposed to putting pipes through the roof. In our '68 I eliminated the bathroom altogether and made it a bedroom, still have sink, toilet and shower (shower outside).
Good luck, Mark D
