- Scamp store sells a door seal kit, fairly inexpensive. It is a soft foam much like what you would put around a window air conditioner. 1/2 x 1/2 for the sides/top and 1/2 x 3/4 for the bottom with adhesive backing. Bottom gap seems to be wider than top and sides.
- The door hinge or hinge pins (both available from scamp) can wear out and allow door to sag or be sloppy enough to not get a good latch.
- The door latch is actually pretty decent, with door adjusted correctly it should latch solidly. If worn badly it too is available from scamp store as an inner mechanism and outer handle. Don't know about the strike plate.
Things you might look at or try.
The hinges are adjustable at least a little bit, best as a two person job. You can loosen the hinge bolts and move the hinges a little in a direction that helps your strike plate and door line up better.
The metal strike plate may be worn or have worn out the screw holes so it has shifted away from the latch. Worn holes can be filled with epoxy then re-drilled after it hardens, possible option to get strike plate a little closer to the door latch.
Really no reason a properly working stock door should fly open. Something is not right if that is happening.
Are you traveling with the door locked or not? I suppose if unlocked the handle could be bounced to an unlatched postion.
I just noticed your in a
scamp 19 I'm assuming (bad RogerDat) that the set up is the same as a 13 or 16 ft.
scamp.
