Gray Water tank for Hawk

I used a piece of 4" drain pipe (5 feet long). I got some rubber ends with clamps. I drilled a hole in one of them on the high side and the other on the low side.
I inserted a 90 degree through-hull connector. I Teflon taped the through pipes and they don't leak. The rubber ends act like a gasket. I used a adapter with a scrap of marine tubing to put on hose ends.
So the sink drain from the camper will go in the high end. Another piece of hose will be in the rear. I put a small air vent hole on the high side of the pipe. I attached the pipe with metal plumbing strap.
If I did it again I would probably use 5" pipe. It is too soon to see how it works.
Here is a capacity chart.

I will let you know how it works.

Great lil' formula for round tanks: diameter in inches squared x yards tall = weight or gals/10 Approximate, which is often just right when working in the field!
On a side note to this thread, how many of you have problems with rodents getting into your gray water? We've had two instances where mice have clambered into our collapsible 5 gal gray water tank. Pretty gross pouring out a dead mouse in the morning!
I should probably work out some sort of cloth covering or rough gasket to thwart the rodentia!

That valve was temporary. I am going to get a scrap of hose to run from the rear connection to just the edge of the bed and have a garden hose shutoff. I can reach up there to that area however from the back on the Dodge and through the tie-down porthole. On my 2001 Tundra I doubt that I could have gotten into there from the rear.I am looking at putting a 3" pipe above my bed rail and below the camper. I have room with a standard Hawk on my 2005 Tundra. I like your tank better and I think it will fit. Do you have room to reach that valve with your camper on the truck? Not sure I have room on the Tundra reach it and may have to redo the drain.

I am going to take off the 6 foot hose that connects the camper to the front of the tank and use a shorter piece that goes more directly to the front without a loop.

I run a hard bucket with a lid and have a threaded fitting for my drain hose, not so much for the critters but to keep my kid from tossing stuff in it... Yuck.

The same design could be used to carry extra water. My truck bed is 8'. A 4" pipe on each side would give me about an extra 8 gallons of water in a space that is mostly wasted.

Needed to put a 90 degree hose connector up front and will have to get another to put on camper outlet, This will allow me to make the hose pretty straight, so it won't kink so easily.
A couple new pictures added to the gallery.

I got the camper back on and everything clears. Added a length of hose to rear of pipe. Hangs out the rear of bed.
