This hitch takes the hassle out of short-bed turns. The built-in rack-and-pinion gear system automatically slides the head back 14" when you turn, giving you safe cab clearance without ever leaving your seat. As you straighten out, it smoothly glides forward again. There’s no lever to pull, no hopping in and out of the cab—just controlled movement that keeps your trailer tracking cleanly through tight turns and campsites.
The wraparound single-piece jaw completely surrounds the king pin for full 360-degree contact. That tight fit cuts down on rattle and chucking so the ride feels solid mile after mile. A 3/4" thick steel locking bar adds another layer of security by reinforcing the connection once the jaw closes. It’s a heavy-duty setup that holds your trailer steady and quiet, even on rough roads.
With a gross towing weight rating of 18,000 lbs and a vertical load limit of 4,500 lbs, this hitch is ready for big fifth wheels and long hauls. The sturdy steel build and rust-resistant black powder coat give it the strength to handle serious weight while standing up to years of use. The solid feel under load gives you confidence every time you hook up.
The rail-free design drops straight into the underbed mounts using the four receiver pucks, locking securely with turn handles and safety pins. When you want your bed back, release the pins and lift it out—no adapters needed. Three hitch height settings—15-1/2", 16-3/4", and 18-1/4"—let you dial in your trailer fit for proper bed rail clearance without extra parts or guesswork.
The double-pivot head moves front to back and side to side so you can hitch up easily on uneven ground, while cushioning dampeners absorb road shock and noise. The result is smoother towing with less jarring through bumps or dips. It’s a noticeable difference that makes long drives easier on both truck and trailer.

One thing to consider - there are a lot of small springs and levers working inside the hitch head to work the king pin jaws. While this 5th wheel hitch is certainly robust and designed to take a beating from your 5th wheel when towing, it wasnt designed to support its own weight for extended periods of time.

Now been two years and have about 15,000 miles on my Demco Autoslide Hitch. Still works terrific with my 35 ft Montana on the F350 truck. Never a problem traveling or hitching up.

The hitch still works as described. Have not broken another rear window since installing it. I have learned that when unhooking from 5vr I have to take a pry bar to straighten out the hitch back to straight for rehooking. The only thing I do not like is the serious clunking that seems to occur when making some turns, then accelerating and the hitch straitening out. Thats the only real complaint I have. Since installation of the Demco I do not worry about making sharp turns!

For anyone else wondering how to use a MOR/ryde pin box with their Demco Hijacker Autoslide, you can use the Locking Plate # DM6025.

After over a year of towing with the Demco Auto slide I am very happy with its performance. Never a worry about tight turns with a short bed truck.

Demco auto slide 18k is a heavy fifth wheel plate considering all the mechanics involved. About 300lbs plus the capture plate because of MorRyde system. But I really like the ride MorRyde gives me so that’s the trade off. The Demco auto slide worked without issues as did the puck system I installed. All came from etrailer and I am happy with them completely.

The overall rating Id give is 4.5 stars!! The issues Im having have been noted in many other reviews. Its Heavy !! Noted.. Its hard to align especially if you had to be off center when you parked. Now, as noted, you must be off-center to connect or loosen the clamps, connect, re-align truck to trailer and retighten the clamps. Gets to be a pain, but necessary if your way off center. Also, it does bang a lot when moving out from a stop which tends to be a bit startling if your not ready. As for the swiveling function, its perfect!! You can really maneuver the trailer basically as needed to get into those tight spots. Just be sure to watch out for anything really close to a 90 degree turn. That it wont do, but you shouldnt be doing that anyway!! Over all, as advertised it does the job! Also, hats off to Demco Cust Service. They ae there when you need them !! And a Big Thanks to etrailer always a great place to shop and they also provide top-notch after purchase support.

Still love this hitch. Hitching is now seamless. Practice makes perfect.

After almost two-year of use, Im glad that I chose the Demco Auto Slider. The clunk is still there and I just got used to driving with the clunk and jerk, but its still better than having to get out of the truck to unlock the slider when backing or making severe turns. This is a set-it and forget-it operation. As it turns out, my trailer is designed with a forward setting king pin, so I probably didnt need a Demco, but thats not how all trailers are designed.

It looks like from your next order that you have the Lippert Rhino pin box on your camper. I wanted to ask you some questions about when you are unhooking your camper. Does it seem like the capture plates are the issue? I do know that that it is crucial to have the capture plates just one sixteenth of an inch on each side of the pin box for a total of one eighth wider than the width of the pin box. Or is the pin box not unhooking from the hitch head properly?

It seems like it not unlocking fully if we pull the handle another inch it slides off.. I lube the clamp helped a little.. if I leave the box on the capture plate seems to help.. The other issue is the chugging in the head is there a way to adjust?..

I reached out to Demco and have some suggestions that will be helpful. Once the trailer is hooked up take a piece of white tape or colored tape and place a piece of the tape at the very front [cab side] of the top of the hitch head in the center. Then place another piece of tape on the pin box itself on the front [or top] in the center of the pin box. Line up the two pieces of tape as you back up and it will help with alignment for coupling. When it comes to uncoupling, it sounded like the trailer is being lifted too high. If it is lifted too high then it will cause the flange on the bottom of the king pin to hook the bottom side of the hitch jaws and causes binding when unhooking. You will also need to place the safety pin in the second hole of the jaw release arm to hold the jaws open. You will also not want to hesitate when pulling out. Any hesitation when driving out will cause the jaws to want to re-close. Placing the safety pin in the second hole of the release arm, will prevent the jaws from wanting to re-close. They were not quite sure what you meant by chugging. There will be very slight bit of movement that occurs with the king pin and the jaws of the hitch. A couple of other things to check, make sure the capture plates on the top of the Demco hitch head are set properly within one sixteenth of an inch on each side of the capture plate.

My initial like for this hitch has fallen. If you have a short bed truck, then this is still probably the one to buy, BUT I have had some issues that I wish I had known about. For what it is supposed to do in terms of towing and turning sharp radiuses, it works great. In terms of hooking up the trailer, not so great. If you have a straight in and out then there is no problem. The really big problem is if you have to hitch and unhitch when the truck is not straight to the camper. You have to be within a few degrees of hitching and unhitching for it to lock correctly. The head of the hitch is stiff enough that it won’t turn any unless the whole weight of the camper is turning it. I’ve had a few times at a campground where I had to unhook my truck at a angle, and it has taken me over an hour to get the camper hooked back up. This has been very embarrassing at times to the point where many other campers with 5th wheel hitches have come out to help me get hitched up. The last time was the last straw. My wife in kids where out in the 90 degree heat for 1.5 hours getting it hitched. I’m done. I’m selling the camper, and I will soon have my hitch for sale. .
Do you have a question about this 5th Wheel Hitch?

That's awesome you had a forklift to use - that's one of the hardest parts of install--just getting it into the truck bed, haha! Glad we were able to keep you informed about the whereabouts, too. Have you been able to use it since install?
