Mystery Roof Leak

We have water coming in at the front edge of the roof vent while it is closed. It has gotten into the ceiling. I got up on the roof and while the caulk is a couple years old, I could find no defects. I cleaned the area and added some leak seal caulk I got from Ace. I’m going to water test it in a little while. 
I can’t figure out where it is coming in. Any ideas?  There was a bubble at the area I circled but it didn’t go through. 
Oh yeah, I had an appointment at NuCamp to get all the caulking checked but I couldn’t make it as my tow vehicle was out of commission. 🙄

    Any cracks, or loose seal on the vent itself?

    @Tampakayaker it looked like the photo all the way around. I couldn't see anything that I thought could leak. Anyway, I slathered it with Lexel. It was recommended by the guy at Ace. We were leaving the next day and I needed to do something. To my surprise, it worked as it poured rain the next night.
    Give me an electrical problem any day over this kind of stuff.   :open_mouth:

    @JeffroNC: Sometimes with calking, you are better off to remove the old and start afresh...This way you will know that you got it sealed, rather then goobering on & on to no avail...

    I once had a car that was getting wet in the trunk. Nothing visible from outside, finally I got in trunk and had my wife spray with a hose, turns out there was a pinhole leak in a body seam, very small let a lot of water in and a dap of caulk in correct place solved issue. Point is sometimes it is a small hole and difficult to find.

    I would suggest using a product designed specifically for RV roofs from an RV supply store.

    And from the unofficial guide this was recommended. I have not had the occasion to try it yet but it seems like it should work in your situation.

    Just don’t use a silicone based product. It won’t last and it can never be completely removed, and nothing else will stick to it.
