Interesting thought on the need of a black tank!
I did some looking at the parts and it looks like the tank itself is not the problem but other parts of the problem?
They actually show that they have two tanks! What we normally expect as a black and grey, are now connected together with one getting the sink and the other getting the shower and vanity water. Those two tanks are connected together at a single dump valve. No black waste as it goes to the canister! But they still have two vents connected to go out the side and one single sensor which I have to assume is a level sensor for both as they are connected together!
Always interested in the what and why of things are done and there must be some good reason for not having a single large tank if they now have two tanks but connected together for function??
Click for better view!
Reason for running the shower/vanity further, crossing over the green tank, to drop it into the tank shown in brown? Reason for two vents instead of one single tank?
Maybe future plans for a different black system are in mind?
Perhaps a different style pump as a macerator/grinder instead of the smaller water pump to transfer over from the stool and shower?
I'm always slow to jump too high on early versions of RV as they have to gain some insight on what works best!
As in many things, new ideas are always pretty suspect if the new folks have no actual experience with the subject!
I'm happy Winnebago has been doing this for long enough to have a track record of success!
