Since I was working on the DIY Capacitive blank tank level sensor (see thread here:
DIY Capacitive tank sensor) I figured I would ask Thor for my 24.1's black tank diagram.
Sure enough they delivered (see attached). Turns out my 24.1 does have a single vent on the roof which is plumbed to both tanks, but it also has cheater vents (or "Automatic Vent Tube Cap" as its called in the diagram) at each sink. Interesting.
Also clearly visible on the diagram is that the lavatory sink is plumbed to the black tank. Since this is on the diagram its clear that this arrangement is intentional (and thus not something you could go back to the dealer claiming as a warranty item "they plumbed my bathroom sink wrong!"). Interesting in that its plumbed to the vent and not directly to the tank... Another thought: since it runs right next to the shower drain you could make a mod and just run the sink to the shower pipe and plug the black run.
Makes me wonder if someone would simply ask Thor for "All the diagrams on the coach?" would they just send out a complete PDF of all the available diagrams?? (instead of this piecemeal thing we've been doing)
