We have had various trailers over the years, and one thing you can count on is screws coming loose, after all it is like putting it through an earthquake for hours on end as you travel down the road. I have found that if I remove ALL screws (one at a time) and apply some lock tight or wood glue on the threads, I have no more problems. If your screws stripped out the wood in the door, you may have to either apply some wood glue to a wooden match and shove it into the hole and break it off flush with the door, then retighten the original screws. If that doesn’t work, you could use larger diameter screws. Most all the screws could also be replaced by small machine screws with nylock nuts, but you would have to counter sink the wooden door screw holes to have the nylock nuts be flush with the door surface.
Best of luck, and keep us posted on what your solution was, and what Scamp
had to say.
