SOLVED: What vent is this?????

[tbhrose]

After uncovering the 3670RL this week, I noticed that a cap / cover had come off a 4" white PVC pipe . This PVC is located between the bathroom skylight and the TV Antenna. Does anyone recognize what vent this is? Please see attachments.

I think that's the vent for the sink/shower drain piping, similar to the soil pipe on the roof of a house. Looking at photos of my 3670 basement plumbing, there are no vent pipes from the Gray #1 tank that would go in that position.

That is an attic vent. It is called a Mushroom Vent. I bought one from this web site;http://www.allrvstuff.com/index.html

Thanks Terry, that's exactly what it is. I took a chance based on another thread and purchased a "Mushroom" vent that was listed as "for Keystone Montana". I installed it this evening with a good wrap of teflon tap on the bolt first! FWIW it is threaded on a 5/16" x 18 bolt. Mine also came from www.allrvstuff.com within 4 days. Mystery solved.

Glad you got it fixed. Before I replaced mine I painted with plastic safe paint so it will take a lot looooooonger before the sun kills it.
