Yes, the black material is a soft pliable weather stripping. The photo is taken with the door open full 90*, from inside looking into the hinge area.
My concern is that the door doesn’t close tight (the weather stripping is not thick or stiff enough to keep door open) a gentle push closed it tight. When I saw that, I looked at hinge. Screws were obviously loose, I tightened them as best I could. The angle to get at the screws is difficult, so I wondered if this was a common problem and if there are any tips or tricks to tightening the screws. On a house door I would swing door open past 90* and get a straight on shot at the screws. The MH door has an air spring that stops it at 90*. I don’t see an easy way to disconnect the air spring, didn’t really want to take those screws out because my experience is that metal screws being taken in and out can mess up the holes.
