My kitchen sink has a rv style and size, of a neg pressure valve with the under sink plumbing, from the factory. This is the vent for the grey tank.
The one I installed is for the black tank. I used the existing piping, except for the end that rises upwards to the roof vent......which is what I deleted near the top in the cabinet.

Misfit have you checked out the layout from below? The tanks are very thin wall, and not alot of lateral room for changes to piping.
Everything is doable, and I wish you the best. Keep us informed.
