I figured that was the gray water drain ... the off-white garden hose connection gives it away.
Down vent on the black water tank isn't good ... vertical vent, through the roof, is better.
Shower and bathroom drains aren't bad but I'd prefer to be able to hook up a hose (maybe a garden hose) to divert the gray water away from the motorhome. (Especially if I'm in an improved campsite.)
My arrows are just pointing to where these things are. The black water tank vent goes out the roof.
Keep in mind, the black tank should be in the cavity under these items. I have NOT re-installed it yet.

I assume the black water vent exits the top of the tank and does a U-turn downward? If so, and it's exposed to subfreezing air, frost could build up in the vent tube. Enough build-up could block the vent, forcing sewer fumes back into the motorhome interior.
A vertical vent is mostly inside the motorhome, effectively preventing frost build-up.
Yes, the vent exits the top of the tank and does a U-turn downward and then back up, through the bathroom closet and out the roof.
