I have a door leak at the front edge of my entrance door. The side where it opens from. There is a small area of rotten wood there. Well it rained last night and there was a wet area in the same place. I started investigating and it is not coming from the gasket side. Very little water was at the bottom of the door frame and none around the screws. It looks like the leak is exterior and not the door gasket at all. The outer door frame does a pretty good job of keeping water on the outside even if there are a few leaks in the gasket. I do think that some Parbond over the screw heads at the bottom would be a good thing. I think that the frame has started to leak at the front edge where the force of shutting the door has broken the seal between the frame and skin. I have seen this exact same rotten place on more than one floor rot thread. My point is, replacing the door gasket may not help the problem. I did not repair the floor yet in that area because I wanted to find the leak first. My first thought was the door gasket but that does not look like the case. When it dries out I will Parbond the door frame and see if that fixes it.
That is a leak source but it is not close enough to the door area. The vent you speak of is the plumbing air vent with the square cone thing? The one that has a rubber sheet with a hole in it underneath?
That's the one, you don't know where the water will leak will show up.
On mine the leak looked like it was from around the air-conditioner the plumbing vent in the front was straight out and did not have the square cone like the one in the rear.
My leak source for an apparent door leak was the front, overhead vent. The rain water came through the vent and followed the inside skin to the door frame. Though the water pooled inside the trailer at the front door, the door itself was not leaking!
Any leak source in the same panel as the door would produce the same leaky-door illusion.

I am going to seal those vents at some point soon as well. It seems like they could find a better way to seal those vents. They use a rubber boot on houses but I have also seen boots made of lead and you fold the lead over into the vent pipe so now it would not leak as long as the lead is sealed to the roof. I think most of them begin to leak when the rubber around the vent splits. What if you put a little backwards facing hat on that square vent thing? That would keep water out and still let it vent.
I think the flat rubber seal with the hole in it is doomed to fail. What they need is a rubber boot that can flex and properly cover the vent pipe and not crack in a short period of time from the stress of poking the pipe through it. It might be possible to adapt a house rubber boot. Something like a car CV joint boot might work well. You could cut it to the right diameter and hose clamp it too the pipe.

Cut my own out of an inner tube, stretched it tightly over the pipe, sealed with polyurethane, cleaned the roof well and did the same with the base.
Oh.... and I added the screws the factory felt I didn't need.

Well I finally stopped my door leak. I sealed the door frame before we left for FL and it rained several inches in one day. Well the leak was still there. While we are in FL I sealed the window to the right of the door. Well yesterday it rained and no leaks so I guess I got it. I know the roof vents are leaking some and I will work on them soon. Maybe I can put some flooring in now that I got most of the leaks stopped. So if you have a door leak chances are it is not the door gasket but the frame or the window frame next to the door.

Mine was coming from the frame also; sealed that a couple weeks ago and several hard rains later we are stil dry. Fingers crossed. Have a pesky one by the compartment door however. Have slowed it down but still small leak. My Avion never leaked like this!
