2017 Forester 3011DS waste tank vent

[bleese]

I have had several travel trailers but this is our first motorhome. Our units have always had a vent for the grey water tank and a vent for the black water tank. Our new Forester 3011DS only has 1 vent which is on the side of the grey tank. While on the roof I noticed all other units in our storage facility have 2 vents. Does the 3011 only have 1 vent?

I have a 2016 3010DS, it has only 1 vent. This seems to be the norm for them.

Yes all the Forester's including my 2801 that I have seen combine the grey and black tank vent and only have one on the roof.

One vent is all you need. Drains quickly with no issues at all.
