My best friend's very large stock trailer (with her horse in it) came off the hitch on the freeway yesterday at 60mph. A very dangerous freeway, at that.
Turns out the trailer they just got has a 2 5/16 hitch and they were using a 2 inch ball.
Thank God the safety chains caught the trailer; thank God their horse is okay and stayed calm in the trailer while they waited for the tow truck; and thank God no one else was involved on that horrendously busy freeway.
A reminder to make sure your hitch matches your trailer and to check your safety chains AND the welds!
