Unusual Roof Vent?

[Ray LeTourneau]

We had some hail come through last weekend and had a little damage. The shower skylight and front A/C shroud are on order. What I can't seem to find is a match for one of the vents. In the picture with the cover and diverter removed, I can't really tell the diameter of the pipe. I'm wondering if this is just an attic vent. There isn't any area below it for a pipe. I have two other roof vents that are smaller, one behind the commode and the other near the fridge. Any thoughts?

Once I used my brain and realized there couldn't be a pipe under that vent, I did a search for RV Attic Vent. Bingo! I found exactly what I needed.

It's called a Keystone Mushroom Vent. It vents the attic. Do a Google search there. There are two or three places to order.
