No pictures of the drain. I bought a compact 3" T that will T a 1 1/4" sink drain into the side of the 3" toilet T. The compact 3" T is shorter than the standard 3" T. Trailer frame is 3" channel iron like most factory trailers. I did not want the drain hanging low to get snagged on something and get broken off. Also I did not want a bunch of ugly PVC pipe showing under the trailer. Toilet flange was attached directly to the floor inside no different that what you have in your bathroom at home. A very short piece of 3" PVC pipe about 6" long was needed to attach the T to the toilet flange. I tested it a few times to make sure the PVC pipe was exactly perfect length for the T to push up and touch the bottom side of the wood trailer floor before I glued it on.
This is not hard to do it takes about 30 minutes doing this by yourself with no help. Attach the toilet flange to the inside floor 12" from the wall then get under the trailer and push a short 6" piece of PVC pipe into the toilet flange as far as it will go then push on the T far as it will go. Measure to see how close the T is to the bottom of the wood floor then cut the short section of PVC pipe shorter until the T touches the floor. Test it again make sure the T touches the floor. Glue it together and your finished with this part.
With the T pointed in the correct direction aimed at the center of the trailer toward the kitchen sink I glued in a small PVC pipe over towards the trailer center then 90 degree elbow up to the sink. The bottom end of the compact 3" T was only about 1" below the trailer frame. It will never be easy to bump the T and break the PVC pipe not even if the trailer falls off the vehicle hitch and hits the ground.
