Here is a general over-view for the roof latches on older four wheel campers . . .
On the older campers, if they screws holding the roof latches to the side of the camper are not broken, don't mess with them.
(if they are working and not broke off, it might be best to just leave them alone)
The roof trim screws at the top of the roof are alot more forgiving and come out easier, even if they are rusted. So if you need to change those out, there is a little less to worry about.
But for some reason with the roof latches on the sides of the camper, if the screw is rusted and you try and remove it, the screw head might very well pop off.
Sometimes just due to pressure and vibration over the years combined with rust, the screw head can pop off as the camper ages. Not a big problem, but I have seen it happen.
The best way for a fix would be to remove the latch from the side of the camper and try and get a bite on the broken screw with a pair of pliers or something small, to gently twist the tip of the broken screw out.
Worst case, you can grind down the broken screw, seal the older screw holes with a marine grade silicone, and slightly move the roof latch over on direction or the other. Drill new pilot holes and install roof latch with new upgraded screws to one side or the other of the original location.
If you had 2 good screws on one side or another, you could put new screws in those holes, seal them up, and move the latch slightly the other direction and re-mount the latch with new holes and new screws.
This way when you are looking at the camper, you will see the roof latch, and just 2 small screws new to it. This might look the best, instead of seeing 2 holes filled with silicone next to the latch.
Hope this helps.
