NamMedevac, that is a clever solution! I will file that one away in the "just in case" folder. Thanks!
Not really that clever. If the TV receiver does not move exactly parallel with the ballmount it can bind and pull the trailer, bending the jack.
I don't think I have ever seen a coupler that did not adjust, and I'm positive I would never buy one.
With the tongue secure on the jack, put your shoulders on the ground where you can see how the latch works. On most there is a wedge that can drop down and back when you work the lever. Now the linkage will pull it up/forward but does not push it open. Once the wedge moves back, the ball is free to travel. But before it can move down in relation to coupler, it must move back. Any bind in the wedge to keep it from dropping on it's own, the ball will not force it. That bind can come from trailer pushing against TV, (or TV push trailer, force is same) if on hill. Or, if trailer is pulling back from TV, the ball is held in the cup-shaped space at the front of coupler. But if the issue happens every time you unhook it is most likely that cleaning and lube will solve the issue.
BTW, most times I unhook I pull the pin, stick the ball back in coupler, and latch it. Protect shins from grease (and knots), keeps road dust off ball, the right ball/mount is with trailer next tow. And most important to me, when I pull the ball out, mount it back on TV, I know the wedge is open to reduce the chance of latching it above the ball/dropping the trailer.
