After much trepidation, I have taken on the door repair. It appears that a previous owner expeienced the "loose door at highwy speed mishap" It has haunted me since purchase. I purchased trailer at a tag sale with no real idea of what I was getting into. The previous owner had rigged door with a brace to
compensate for break, so it was not apparent how bad the damage was. When I removed the brace I realized that the frame was badly damaged. In my mind I pictured a mass of fractured pot metal held together with sealer behind the skins. I considered replacing the door, but found them rare and expensive.
My repair cost about $250 with welding and misc.
