2014 3100RL with a Demco Autoslide - Hookup Problems

[TenOC]

We have a 2014 3100RL Montana with Mor/ride RPB72-1116 King pin with a Demco Autoslide 18K 5th wheel hitch. We like the hitch EXCEPT for one problem that exist since we had the trailer.



About 50 to 75% of the time when we hookup the king pin is not fully seated. The safety pin will not lock in place. The hole for the safety pin is off by about 1/16 to 1/32 of a inch. We need to drive forward and back a few times to rock the trailer until the king pin is fully seated so we can insert the safety pin.


We have tried different heights of the trailer when we back into the hitch with no joy. We do no know why sometimes it works and other times it does not.



Any other people have this problem? We have talked to Demco with no solution. All suggestions are welcome.

If you aren't already doing this, it might help. When you back into the hitch, make sure the pin box is lower than the top of the hitch so when you contact the hitch, the pin box will ramp up onto the hitch. This will stop the high hitch problem.

This is what we always do.

I don't have your Hitch, but mine is so tight that I have to generally leave the Truck in reverse to put enough pressure against the pin to allow the jaws to fully close and lock into position. Of course you need to make sure your Rig is chocked and not going to move.
