Here's a new one. when I went to hook up our tow car this morning in Albuquerque I pulled on the base plate and it wiggled back and forth. I have been noticing a grinding action while Towing the car the last few days and to my shock, two of the three attachment bolts had fallen out of the base plate. on the other side one was sheared off. It wasn't any way to put new bolts in there on my own because the inside was inaccessible without the bumper coming off. Admittedly our tow car is a big one, a Hummer H2 which our Monaco Dynasty tows very easily and every few years I actually replace the Blue Ox hitch to make sure I have one that hasn't been stressed for a long time. there wasn't anybody in Albuquerque who could fix it right away so my wife jumped into the car and drove it herself. following the RV back to Phoenix where we can get it repaired. So my tip would be once in a while, when you're checking your hitch check the bolts on the base plate to make sure they have them jiggled out or sheared off. I called Blue Ox and they were amazed also and told me not to use it as it could cause an accident
