I'm not very successful so far in uploading an image. A friend with me couldn't believe the quick responses I got from you guys.
So one of my potential fixes involves using magnets so I was glad to see that. And my doors do the same thing with popping open in route or when I sat on them.
I can't "repair" the holes because the holes were never in wood; between wood. (I actually initially drove anchors into the holes and hoped that would hold but it didn't)
I didn't get this: "I drilled 3 or 4 holes in each piece of wood that had come away from the back of the dinette wood backing. I just used wood screws. This closed the gap and now the screws are nice and tight." Though that side did have an additional piece of wood behind the outside piece (other door didn't have it), it too was situated such that it's seam fit the same one as the outside so still no wood for the screws to go into.
So these are my questions:
1. The original placement was slightly off the floor and I couldn't figure that out since it had to support the wt. of someone sitting on the cushion above it. One of you mentioned it having to flex as the slide moved. So when I replace the door, should it not sit too much on the floor of the slide?
2. If I move the placement of the screws to the right so they are in wood and use magnets on the other side instead of the latch, I think it might work. This might mean that cold air can come through a gap where the magnets set it out but I can just put glue-on insulating strips if that's the case. So might this work?
(I originally moved the screws on the door itself and didn't realize the door wouldn't open fully that way. Retrospect always makes you feel stupid. So thought I'd seek out your opinions before trying again!)
