stuck coupler

If you're sure it's unlatched, you could tap on it with a hammer (not enough to dent it) to see if you can free it up. Spraying a penetrating oil (like Liquid Wrench) may help, too.

Possible issues that can cause this are rust or using an larger ball than the coupler's size.

On a ball coupler, there is usually a "jaw" that comes up from behind the ball to secure it in the coupler. It is visible from underneath the coupler.

Get down on the ground, or get a mirror, and look while you operate the latch on top to see what the jaw is doing. Is it moving at all? Is it not moving enough?

BE CAREFUL. Don't put your head or any body part under the tongue of the trailer. It would be just your luck for the coupler to finally release, and drop the hitch on your face.

Rust should not be an issue on a 6 month old trailer unless you towed it through knee-deep salt water. It is likely either a faulty coupler or an adjustment issue.

I am not sure about yours, but on my boat trailer there is a nut on the bottom and can be loosened slightly to make it looser or tighter. Also as was stated earlier check to see if the ball is the right size. A 1 7/8" and 2" ball are similar in size if your trailer takes a 1 7/8" ball. JMO

I've had that on my TT when it was new and have seen it on the Jayco Owners forum. It will get better with time as paint rubs off the parts from use. In the mean time some spray lube will help.

My Brand New Roo has issues. Sometimes, a few taps from the pipe I use for my WDH is all it needs to come free. I figure it was new and would need to be worn in.

Too much down angel on the ball has caused mine to be sticky, but always came loose before the rear tires on the pickup came off the ground.

Mine is in it's 3rd season and sometimes the ball still sticks. I have to jump on the hitch to drop it down. As said above, make sure the parts are moving.

Mine does this occasionally, I believe its mostly because of the pad my trailer sits on is not level with the driveway I back the truck up to.

Usually I hit it with a hammer. If that doesn't work I press the gas gently in forward and reverse then slam on the brakes immediately. If I do that a few times it will generally always jar the ball loose.

Thanks for all the suggestions. I'll go back to the storage site tomorrow armed with some heavy duty tools to see if I can break it loose. Could the coupler be damaged?

x2 should be adjustable and of course be sure your ball size is right.
