Having had a fiberglass camper jump the hitchball from being worn out at 65 mph on a rough road... replace the coupler spoon. Trust me when I tell you, it's much easier to replace it than to deal with the aftermath. I was lucky. There was no one else on the highway when mine happened, and the damage to the trailer was negligible... but if it'd been our 34' at 9,000 lbs instead of a 1500
lb fiberglass trailer behind the Excursion, it would have undoubtedly had an very different outcome.
As Ken says, it's not difficult to do and doesn't take long, but it's certainly worth the peace of mind (and safety).
