How are most doors sealed at the hinge?

I have no picture but Scotty had cloth tape that ran down the door and the jam which covered the hinge. It was od and dried out so I peeled it off. I'll place it with something after painting the door frame.

Mine had a piece of some type of vinyl material over the hinge. I'll try to get a pic tomorrow sometime.

Same here, I have ventilation through the hinges. Mine had no evidence of ever being sealed. And a note about the jalousie windows, if you notice, the seal at the bottom of the window does not go all the way to the end on one side. At first I thought they had just worn like that, but I bought another window and it was the same way. Looked a my other trailer, same way! There is a gap there for ventilation. I did have to temporarily seal that gap on the front when it was raining HARD and the water was getting thrown UP the front of the trailer while I was traveling. It looked like a fountain shooting up the window!

It's funny because I don't notice the daylight in the hinges until after I finished the trailer and was camping in it. I'm going to try some weather stripping and see how that works, one day. But it's not really a big deal. No water has ever come in my door and I've been through some big storms.

The water that came up through that little tiny spot in the window didn't hurt anything. It was right in front of my sink/counter. It scared me when I first discovered it because I had stopped to get drinks out of the camper and there were sprinkles of water on the counter. Of course I thought "leake." I was relived to look in my review mirror and see the fountain shooting up in the window. I stopped, opened the window just a little and stuck a sponge in that corner and shut the window on it. It was all I could think of at the time and it worked. I drove through torrential rain after that, with no sponge and it didn't happen.

My trailer didn't have any seal on the hinge either. It did, however, have lots-o-rot in the floor by the door. When I camped in a big rain storm I had some water come in there. I'm not quite sure what I'm going to do about that yet. This thread has gotten me thinking about it again.

Hmm. My door opens opposite to what you are saying mobiltec, so my hinge is in the side toward the front of the camper, and nothing covering the hinge area from the elements. Its interesting what you are saying though that makes a lot of sense.

If you wish to seal the hinge side you can buy some small foam tape, it is about 3/16 thick and very soft install it and most of your problem will be solved. Some hinges gap enough to allow insects/mosquitoes in.
