Gray water tank - 1971

How hard is it to add a gray water tank? I am inquiring about adding a tank to an AS that needs no other work or restoration.

I am in the process of doing that very thing. I am doing a shell-off rennovation, so adding the grey tanks is a fairly minor part of the fun. It is hard to tell you the level of difficulty without knowing the range of trailer years you are looking at, but it isn't rocket science, many of the vintage trailer owners have made this modification. It isn't a "cut and paste" sort of operation either--you will be performing a customization that is going to take some thought and planning. There is no "out of the box" solution.

The biggest question that plagued me was whether to use a single large tank that would hang below the belly, or to use two very shallow tanks that would stay within the frame rails. Once that decision was made, and the tanks acquired, I have actually been able to make some steady progress.

good luck.

I am in the process of putting 3 in. 2 grey tanks and 1 fresh tank on top of the other fresh tank. Mine hand bellow the belly pan as I wanted 60+ gallons of capability. The key is finding a why to get your plumbing to them, not the tanks. you can get tanks here.

We also added gray tanks - two of them. One is 4 inches deep and sits above the rear axle. The other one is 5 inches deep and sit behind the rear axle, and it hangs below the original belly pan about 1 ˝ inches total including the frame and plywood support. I customized the belly pan to enclose this tank when we installed the new belly pan this year. I also built the tanks myself to maximize the space in between the main frames and cross members rather than pay for custom sized tanks.

You can get details in our thread: http://www.airforums.com/forums/f185/little-girl-refurb-50967-19.html starting at post 259.

Chris,

What technique did you use to construct your own custom tanks (fiberglass, plastic weld, etc)?

I should have stated that I am looking at a 1971 Globetrotter that needs very little work but needs a gray water tank.

Minimal effort new gray tank

I would use the gray tank that Vintage Trailer supply has available. It fits within the belly pan limits, which means minimal, if any belly pan alteration.
You would still need to alter the incoming drain lines and vent up in the cabin, as well as either tie into the outgoing waste drain line, or create a second one.
I think whatever tank you choose, there will be at least some slight frame additions/adjustments to support the tank.
On the flip side, you could get a much bigger tank, if you can extend below the belly pan....a little more work.

Ok, here is a picture of my upside down frame sans-axle with two vts tanks installed. If I had had to do everything I've done in the last few weeks from the underside of the trailer, I would have thrown in the towel.

Wow, Bottom-side up would make it easier. Do you have a rotisserie to spin it around? I dropped ABS tanks from the top-side, but if you put them in from the bottom, I am guessing it would have been as difficult as the VTS tanks. I don't think there is a magic bullet for this task.

from what I can see in the pic, it looks like when you flip that thing back over, the tanks are gonna just fall out. How do you propose to prevent that?

You can't see the wads of bubblegum under the tanks! Seriously, I made panels that will slide into angle supports much like the panel that supports the fresh water tank. I'll slide them into place before I flip.

My comments earlier about all that I had done recently and throwing in the towel was more directed at the fact that I replaced the entire belly pan. The tanks were the easy part.

Aero wood--thanks!

Bauxter--no rotisserie, I used the two gantry frames I built and used to lift the shell and three chain hoists to flip the frame. Worked pretty slick.
