Does a 1971 Airstream Overlander have a grey water tank?

Nope. We have a cap with a garden hose connection to drain the grey when boondocking. We have been using a bucket when using public parks, but just ordered a blue boy since we are planning a 9 day trip to BC and using Provincial Parks.

If you have it capped off, there is enough room for a couple of quick hand washes, for anything more and it will backup--which you want to avoid because it can backfill into the black tank causing contamination of your grey water drainage lines and basins.

I do wish there was a grey tank. It is probably my only dislike of the systems on our 72 Overlander.

We get this same question on the forum several times a week. No Airstream built before 1973 has a tank for sink or shower water. It drains through a pipe and out onto the ground, unless you cap the pipe. Then it backs up in the shower.

Why not just install one?

1971 Caravaner plumbing help

S.O.S!

I have 1971 Caravaner. It’s in good shape, electric and gas work but I am having a hard time figuring out the plumbing.

1) how do you flush the fresh water and sanitize the pipes after winterization?

2) where is the black water tank and the valve that closes the drain so you don't open the drain and get poo all over you and the ground?

3) there are two water hook up’s one is on the back near the sewage drain that hooks up to a hose and another is on the side of the airstream where the water pump is. It is white and has a screw in it and pulls out, it look like a pvc pipe cut in half..?? which one do I fill?

Please help. I need help to flush my fresh water and make sure black water is draining properly?

interested too

So I have a 73 Tradewind, no real grey tank either, there is an added tank below the rear that catches grey but its small, it hangs down low, and leaks from the top when filled. Need to get a grey tank. Can you install fro bellow the trailer without removing the floor? Max Well has the set up I am looking for, i think. MPJ

I have installed gray water tanks on 3 different Airstreams. I have used the shallow ones that fit above the belly pan but prefer deeper tanks with sloped bottoms that have more usable capacity and drain more easily. The last two I have installed hung down 5-6 inches below the belly pan and are protected and supported by an aluminum plate that bolts to the frame members from underneath.

The water hookup on the back is the street water connection.

The one my the door is for fresh water holding tanks

The black dump valve is in the trunk

I would add a grey water tank perhaps if I was doing a shell off resto too, but as it is I have no plans for one because the blue bow has been very effective. We have been to a couple of rallies now that were long enough for our neighbors to fill their grey tanks, and the had to borrow our blue boy anyone.
