Try lifting up on the lever, then move the truck just slightly forward and backward listening for it to drop into place.

Tried that, but will try again.. Is it possible I bent something? The trailer is a brand new Interstate. Thx

Borracho

Dang it... That's what I thought... I hope I didn't damage it. It's a brand new trailer....

Is the trailer coupler stamped with the correct hitch ball diameter? In other words, 2" ball, 2" coupler? or are they mismatched.

You may need to adjust the coupler a bit to loosen the latch a bit so the ball will go further/all the way into the connection. Look under the trailer coupler (lay down on your back and look at the underside), should see an adjusting screw or nut, get the right sized wrench and adjust it a little bit at a time until the coupler seats fully down on the ball.and you can engage the lock mechanism. A little bit of play in the coupler lock is ok when the coupler lock is closed and the coupler will slide a bit on the ball. Lube the ball and up inside the coupler with a thin film of grease. New coupler and new tow ball means they be stubborn at times.

That was going to be my guess, 2in coupler on a 2 5/8 ball?

Borracho

The hitch and ball are both labeled 2 5/8. It used to drop before. I just took the hitch off and it still doesn't drop. I should probably start a new thread since this is a show stopper for me. The reason I bought a new trailer was so I wouldn't have these problems!

I have had problems getting our trailer off the ball but never had an issue getting it to lock on it. Weird.

Have you tried greasing the ball and underside of the coupler? I started doing that about once a season and its made a huge difference.

Borracho

It doesn't drop even off the ball. Posting new thread.

Might not need a new thread. Like Jeff just noted, the thing prob needs lube. Bingo.

Too, once the trailer is uncoupled again and resting on the tongue wheel, get your face up in there and have a look while you or someone else actuates the coupler locking lever. See what's going on, yourself.
