So the trailer jack on my ancient Shorelandr is leaning, making me wonder how long I have before it fails. The jack itself isn't bent, but the steel brackets that secure it to the trailer frame are flexing. What's the best option here - spring for a new trailer jack or just try to find some new brackets? Anyone done any research on higher quality trailer jacks? I've seen a number of them but they all seem to be made in China? :?
