Small gray water tank on First Gen Tundra with Hawk

Got tired of having to put out the bucket and hose when I need to use the sink. As with most things I do I had to do twice, I first mounted the tank high. When I put the elbow on it was out 1/4 inch to far. Had to lower the tank to be under the wheel cut out and move the fill point. Just enough room for a 3 gal tank. 4 inch PVC with caps on each end. I drilled and tapped all the hole and put epoxy on the threads and tighten them down. I drilled a hole next to the tail gate opening for a 1/2 inch copper drain pipe. Vent pipe is ty-wraped to the jack bracket.

If I did this again I would mount the tank to the camper under the wheel cut out, there is room on the Tundra with the Hawk. I would put a 3 way valve under the sink so pipe would connect to the new tank or be switchable to the out side drain. The tank drain would have to be run behind the heater (this would be more work).
