All in all it turned out pretty well.

Here you can see the discharge is the same distance from the frame rail as the original, just moved 2” to the rear of the trailer.
I’m currently repairing a crack in my grey tank so I haven’t completed the exterior plumbing yet. It’s easy though. A small stub of pvc glued to the threaded coupler in the bottom of the tank, then join to the old 3” with a rubber coupler. Then shorten the 1-1/2” side by 2” and reconnect with either a glued coupler or a rubber coupler. I will post pics once that part is completed.
