You are correct. There is no gray water tank on a 1973 Airstream travel trailers as it is a feature that did not become standard until 1974. Even in 1974, the gray water tank was quite small by today's standards.

Vintage Airstream owners typically handle the situation in one of two ways. The simplest is to carry a "blue tote" or "blue boy" -- an auxiliary blue plastic tank designed to collect the gray water that is available at most any RV accessory store -- these can be emptied at the dump station or the smaller ones can be carefully emptied in a standard flush toilet. Those desiring a "permanent" solution add a gray water tank to the coach, but that involves a number of engineering challenges and often results in a tank that is smaller than ideal. I utilize "blue totes" with both of my vintage coaches.

Good luck with your Ambassador!

Kevin

That's how I felt
I added a gray tank.
the blue boy wasn't bad, I had the big one.

but the Thetford valves leaked, my black tank was broken, and so on. Just remember Airstream's are adventures, not just for going on adventures

Beans, did you have same floorplan as mine? How, where did you add tank?
Does anyone know how, where to add what size grey tank to 29' rear bath, twin bed?
Thank you very much.

Our Trailer is a 31' center bath, I bought a 37 gallon tank off of amazon, and modified my frame and lifted the trailer to make it fit.
I believe there are pictures of it on my rebuild thread. Search my created threads.

there must be easier ways than what I did, but I had it torn down to the frame at the time, and I wanted the volume. I also plan to add a diverter valve to run the bathroom sink into the black tank when desirable.

Hello from Colorado, welcome to the vintage Airstream hobby. You gotta post some photos of your 73 Ambassador 29', both exterior and interior. I bought a 75 Overlander 27' a year and a half ago. It is also a twin bed, rear bath.
Here are a couple of photos of it the day I towed it home.

Our 45 year old Airstreams certainly have needs. I know canofbeans has done major, major work to his Sovereign including the addition of a nice sized grey water tank. My 75 Overlander had a 10 gallon grey tank, quite small. I have added new grey and black tanks to my trailer during its renovation. You might like to read over my "project thread" and see all the areas I have addressed in renovating my Overlander. I'm driven to complete it this spring for the upcoming travel season. Can of beans has a very good project thread too.

You might want to do an analysis of your Ambassador to determine what it needs. Start at the ground level and work your way up. Chances you will find it needs a lot just like mine did, and just like can of beans did. Then decided what to do first. I might suggest that painting the cabinets or polishing the exterior isn't the most important thing. Axles, brakes, bearings, frame and subfloor need checked first.

These Forums will be very valuable to you as you work on your Ambassador.

David

Hi E,
Welcome to the club! Nice looking Ambassador...

As "Colorado David" said, this forum is fantastic for learning all about Airstreams. My wife and I have a similar model to yours, and it is incredible how much I have picked up from the great people here.

I was puzzled by the very same question that you asked. In my case, the rear floor was soft, so everything in the bathroom was removed to get to the floor. At that point, I could clearly see how the plumbing was routed. The short version is that only the toilet drains into the "black" (and only) tank. The grey water (kitchen sink, shower and bath sink) drain to the Thetford valve assembly (the one kind of sticking out the rear of the Airstream). That grey water meets the Thetford valve assembly DOWNHILL (closer to the exit end of the valve) of the sliding valve that drains the "black" waste. In the old days, that water might not have been collected, but just would drain onto the ground. Now, people use portable tanks, as referenced earlier...

In the picture below, the toilet connects to the biggest inlet on the far left (still on the top of the tank), the other hole/connector at the far right in this picture is the vent, and the grey water comes via the black pic pipe over the top of the Thetford valve and into the waste end (after the valve that opens from the nasty black water)...

Hope that helps :-)

Many owners (such as myself) converted to a composting toilet, and then the existing black tank became a gray tank. Before ripping stuff apart, maybe consider how you're going to use you Airstream? If it's just weekending, you can probably get away with the combined tank. A lot of boaters use a 5 gal. bucket full of water for initial rinsing of dishes, then a quick fresh rinse.

We have a tendency to mostly use campground showers and toilets anyway...

My 71 GT had a grey tank mounted just behind the axle below the belly pan. The plumbing was rather convoluted but functional. The tank looks to be readily available

Your Trailer looks like it's in great shape. must have been stored inside mostly? That would prevent a lot of the common rot problems.
some things rot from no use though, so check your appliances carefully.
our furnace looked like brand new except where the water had settled in the burner tube and rotted a hole through. I'm glad I checked it before I used it. I would also recommend cutting the rear trunk lid from the body and attaching it separately, the system Airstream has to direct water from the trunk lid directly into the rear floor plywood is a design flaw they hung on to even in the newer trailers.
