How Do I Unlock the Sliding Mechanism on My Reese Square Tube Slider?

Question:

I have the square version slider. I found that the only way to get the locking mechanism unlocked to slide is to lift some of the trailers weight off the hitch. The rolling lock mechanism is in contact with the square tube and not able to unlock otherwise. Is this a design flaw or how this product is supposed to function. It’s an annoying extra step I’d rather not have to do. Considering switching to a different brand.

If you have a square version Reese slider like the Reese 5th Wheel Trailer Hitch w/ Square Tube Slider # RP30051, I confirmed with my contact at Reese that there could be an issue with the hitch not sitting squarely in the rails during installation. The best way forward is to loosen the rails and readjust it to be a proper fit so they are properly square. Also, when you try to unlock the lever, make sure to push the lever all the way to the stop. Try not to jerk on the lever if at all possible. As far as functioning, the hitch should freely slide without lifting off weight.

Another thing to consider is proper lubrication. Reese recommends keeping the slide lubrication with white lithium grease like LubriMatic White Lithium Grease # L11354. Without lubrication, a lot of the mechanisms will not work properly on the hitch.
