looking for my grey water tank?

Peeling back the layers of a 57' flying cloud. I am down to the tanks. The black water tank was above the subfloor and I assumed there would be a grey water tank below the sub floor over the axel. I took the bottom pan off under the axel and just found dirt and insulation. I did read somewhere that before 1960 all airstreams were "park models" is this true? The subfloor is solid and the frame only seems to have surface rust. It was kept in Eastern Washington for most of its life. I was hoping to put grey water in from below. Thoughts?

Thanks,

Mike

Back in the day, it was common for grey water to be discharged on the ground.

Our '69 doesn't have a gray tank.

If I recall it wasn't until '73 or '74 that gray tanks were installed.

Back in the day dumping gray water on the ground or down a gopher hole wasn't a big deal BUT not any more.

Heck the owners manual even gave instructions on how to dump and cover the Black water and Airstream even sold a cover plate for the hole you dug while in use.

My ‘69 Avion did not have a grey tank. I just finished adding one though.

In the early 70s dumping grey water on the ground from RVs was outlawed. You should have 4” frame members. We installed two grey water tanks in our 55 FC from VTS. They fit between the Main frame members and were 3-7/8” in height. Just make sure to consider weight distribution. Good luck. Bubba

You could get a "blue boy" portable tank. Can be used for grey or black water and then wheel it to the dump site.

Hello

If you don't have a shower in the trailer you may consider my approach. I ran a gray water drain line to the black water tank. I also put a ball valve on the gray water line so I can divert only the gray water to drain on the ground when I am boon-docking. There is not that much gray water, only from the kitchen & bathroom sinks. I do have a setup for an outdoor shower if I boon-dock for a long period. It works fine for me.

Good Luck
MC

I don’t have any. I worked on it sporadically over a year.

Bought a tank from vintage trailer supply and had them spin weld fittings in.

Basically I had to cut 2 frame crossmembers out. Weld in some supports that would clear the top of the tank.

I made a mounting frame or cage out of angle iron and cut a piece of aluminum plate for the bottom to support the tank. Coated all of that with bed liner.

Bolted it to the frame and used screws into the floor and sprayed great stuff foam in spots to keep it from moving in the frame.
Then used some thin aluminum to skin the bottom of the frame to look as factory as possible


Then it was a matter of drilling a hole for my vent line in the floor under the bed and running a piece of tubing through the wall into the shower vent pipe, and plumbing the water lines.

It was more involved than I thought it would be. Had a baby and other issues while I was working on it. So that’s why it took so long.

In my 71 Land Yacht 19' the grey tank is under the couch on the driver side under the subfloor and in front of the wheel well, which is across from the kitchen.

My 64 Safari didn't have one. I am adding a 12 gallon grey tank for use during traveling. You can thank the EPA for a myriad of dumb laws enacted since the early 70s.

Yes, except for when you use the outside shower..... go figure.
Must be a new law just waiting to address that.

I'm QUITE sure our wonderful California legislators are spending tons of time working on such a law already...
