SAFETY WARNING FOR TOADS

While the hitch was original equipment, the RV was purchased used (according to the OP). That damage could only have been caused by either overloading the hitch with too much tongue weight, or reasonable tongue weight but using an extreme drop or hitch extension, or finally, the RV being backed into something with the hitch taking the blow. Since we don't know what the previous owner did, there's no way to tell which scenario caused the break. But it is still a good idea for ALL of us to routinely crawl under our rigs and LOOK at things.
