Pulled boat out of garage. Drove to the end of the block. Came to stop from about 15-20mph. Trailer ripped off ball bending pin in the process. Came off hit tailgate, hit bumper on the way down and slid under back end of truck. Boat seems ok thank god. I get out and look. Latch still closed. Manage to get pin out. Pin bent about 45 degrees. Fulton Winch side plate completely cracked off and arm winch is attached to slid a couple inches pushing bow eye onto roller, winch gear completely mangled, where swing arm attaches to main portion of trailer bent out. Not sure how this could have even happened. If I had gotten on the main road or freeway and this had happened it could have been real bad. No fishing this weekend:-(
