Sliding hitches usually mean stopping, pulling a lever, and climbing back in—but not here. The Demco Autoslide automatically glides up to 22-1/2" toward the tailgate when turning and slides back to center when straightening out. The roller-and-guide system keeps the motion smooth and controlled so you can make slow-speed turns easily in tight spots without binding or jerking.
The single-piece, wraparound jaw closes fully around the king pin for 360-degree contact, giving a tight fit that reduces rattle and chucking. A solid 3/4" thick steel locking bar reinforces the connection and automatically locks when the jaw closes. With less play between the trailer and hitch, towing feels solid and quiet mile after mile.
The double-pivot head moves both front to back and side to side to make coupling easier on uneven ground. Three polyurethane dampeners cushion those movements to help absorb road shock and cut down on noise. Hooking up is simple too—the head automatically tilts into place as the king pin slides in, so there’s no wrestling with alignment.
With a 13,000-lb gross towing weight rating and 3,250-lb vertical load limit, this hitch has the strength for serious fifth-wheel hauling. The steel construction and rust-resistant black powder coat finish stand up to years of use. It mounts on a custom underbed rail kit for a clean bed when removed, keeping only sturdy connection points below the surface.
The hitch arrives pre-assembled—just bolt on the side plates and attach the head. Three height settings from 15-1/2", 16-3/4", and 18-1/4" make it easy to dial in your trailer’s level ride height and proper bed rail clearance. When not towing, remove a few pins to lift it out of the underbed receivers and regain full access to your truck bed.
Ratings & Reviews
So far so good. Hitch works as advertised, although it isn't always facing straight while towing. That has me concerned. No worries about the 5th wheel hitting the cab. '21 F350 SB.
The new lower base for the Demco hitch arrived on Tuesday via Freight it was a great interaction the driver I actually knew from a previous delivery, me and a friend were able to lift the old one out of the bed of my truck and install the new one today and all I have to say is...
PERFECT FIT!
It appears that Demco has already redesigned the lower base compared to my original one to prevent this problem from happening again. I was actually kind of shocked to see that upgrade and change.
I cannot say enough good words about you with etrailer and Demco working with me to get this problem solvedm Yes it took a little bit of work, ultimately this time we got it. I cannot thank you guys enough.
My friend and I will be finalizing the installation and getting it locked down to the bed with a few custom spacers for the lower rails this weekend.
Here are a few pictures of the installation resuming. If I remember , when I finally pick up my new camper, I'll send some pictures along too. Have to give credit where credit is due . Not sure of you have a customer wall at HQ. I know we had one in my old shop.
Anyway.. thank you again .
Well built fifth wheel hitch. Haven't got a chance to tow our new Montana High Country 295RL. But I know a guy that has towed his fifth wheel with this same hitch. I'm sure this 18K hitch will be excellent! Or I wouldn't have bought it. I recommend e trailer for everything.
Don’t recommend trying to muscle by yourself. I’d recommend a cherry picker if you have one or a good buddy. Not light, which I think is a good thing! Goes together smoothly! Built extremely well. Fits perfectly with titanium box and a bed cover when not in use.
Easy installation and works great. I love how it works. Thanks
I just received my Demco hitch, it arrived in 1week very fast shipping. Everything looks to be in good condition, haven't installed it yet so hopefully the install will go as good as the shipping did Keep up the good work etrailer.
What is the truth? It’s a gray hitch saved my ass in many ways and unfortunately I give it two stars for one reason loan it’s incompatible with a lot of lightweight trailers and there’s no help with that. There’s no adapter to be listed. This goes on and the simple solution would be to extend the bolts that latch onto the trailer itself on the kingpin head. That’s really the only problem.
The Demco Auto slide takes the worry out of towing my fifth wheel trailer with a short bed F-350. I have had no problems with backing into tight camping spots. And since everything is automatic I have one less thing to worry about while traveling with a fifth wheel.
The only problem is that it is a little on the heavy side, so I just leave it in the truck when not towing. Problem solved.
I am extremely happy with the product.
Item works exactly as described. I have a shortbed (6.5') Ford F350. Probably towed our 5th wheeler 5000+ miles with no problem. Then last year it happened! We were making a sharp turn in an uneven lot and POW, the 5vr hit the rear window and it exploded. After that I became gun shy about turning with the 5vr attached so I started looking at sliding hitches. A slider that you had to get out and unlatch to make work, didn't make sense to me. At what point do you get out? So, an auto slider hitch was purchased. Now when I get to a certain degree turn the auto-slide hitch moves back in its carriage and then auto-slides to the normal location once straightened out. Not gun shy anymore.
Pro:
Well packaged
Well made
Easy install
It WORKS.
Cons:
Price
Very heavy
Some clunking after it straightens out from a turn
Very happy with my Demco Autoslide hitch after one year. We pull a Montana 3120 35 ft 5th wheel with a 2019 Ford F-350 short bed. Took a month long 6,000 mile trip from Colorado to New England/Canada this Summer. Lots of hilly/curvy roads and some remote campgrounds with tight corners and some near 80 degree back ins. Never came close to trailer contacting the truck. I’ve had no jerking or other issues when turning or stoping/starting. Works great. The only drawback is there isn’t much room for error when you back up to hook up the trailer, so it takes a little practice to get used to correctly lining up your Demco Hitch to the trailer. The first couple of trips, it took me 3 or 4 attempts to properly line it up. No longer an issue for me after a few trips and you get used to the angles. It weighs about 300 pounds. I got a small chain hoist which I installed in my garage rafters and easily lift the hitch in and out of my truck and just let it hang front he rafters until I need to use it.
This 21K unit is very well built. It does have some weight to it so some help installing would be much easier.my installation was completed solo and took approx 1 hour in a GMC 3500 Denali.
Heavy as hell. Shims should be in smaller increments. Took a sledge hammer to get pins to finally seat in pucks and to close the locking handles. Took apart and back together 5 times to get it right. Not enough play in the system in my opinion but I have zero experience with OEM 5th wheel prep stuff so who knows. Ultimately in the end it's installed and feels tight. Backing 90 degrees i didn't see and slide but maybe it knows what it needs to do better than I do.
The product is very well built. The instructions could use some clarity on exactly which bolts go where.
Hitch is amazing. I was worried about towing a 5th wheel with a short bed. Hitch works as advertised. Easy install. Thanks for the help and fast shipping.
The product showed up in perfect condition. Followed the instructions and install was pretty smooth. I had access to a forklift so I was able to do the install by myself. Just be aware that it’s a freight shipped item so the estimated arrival time is wrong. It will take longer than what the website tells you at checkout. But the customer service reps were helpful in explaining the process when I inquired as to where my package was.
I like to hitch but unfortunately doesn’t work for my trailer as it won’t travel level meaning it was to high in the bed of the truck causing to much weight to be on the rear axle of the trailer which will cause other issues like wearing tires, wheel bearings, axles and could cause rear tires to blow out while traveling. With discussion with Will at ETrailer we worked out to use a stationary hitch until one can be available for our situation. Will was excellent to work out our options.
Installing was relatively easy. Made my silly Rhino hitch work with auto slide.
This hitch is very well made. Its very heavy and will require some kind of lift to get into the back of the truck. I used a foldable engine hoist. The puck system works well as long as the pucks the truck manufacturer installs are cast correctly. One of the RAM pucks had some slag or casting imperfections that had to be removed for the hitch to go into the puck. Once that was cleaned up the hitch installed very easily. Another thing is this hitch has no rattles when I am not pulling a trailer.Very impressive to other 5th wheel hitches I have used. The hitch works as intended as I do not have any issues with clearance in a full 90 degree turn. When turning at a 90 on a grade or large angle which sometimes causes clearance issues this hitch I have not had any issues.
Working perfectly. Delivered via LTL, the carrier called in advance to schedule delivery to our home. I requested a lift gate at delivery. Driver picked up the (1) skid (approx. 500 lbs.) with pallet jack, moved it to the lift gate. I backed the pickup truck receiving the hitch to the back of the carrier truck and put down the tailgate. Driver lowered the lift gate to the same level as the tailgate of the pickup truck and moved the pallet from the lift gate to the back of the pickup using the pallet jack. All done in the street in front of our house. No problem!
I assembled the hitch in the rear of the truck by myself. Everything lined up perfectly with the "puck" system. Install took a few hours since I was on my own.
First hookup with 5th wheel was a little problematic. Hitch would not engage when the king pin hit the back of the hitch. Being new to a 5th wheel hitch, I thought I was doing something wrong. I got a neighbor who had years of experience with 5th wheels to take a look - we still were having problems getting the new hitch to engage. As it turned out, the king pin on the camper had a little corrosion, which we cleaned off and added a little grease. We added a touch of grease to the new hitch at the point of contact with the king pin. Hooked up on the next try and every other try (probably a dozen or more) since then.
Did some practicing on sharp turns and the automatic slide works perfectly! Full clearance between cab of truck and camper in all the turns we attempted. I did a lot of research and stressed a good deal over this purchase - so excited it worked out. Knowing what I know now, I'd do it again!
Worked out great. I used the hitch for my camper right after I installed it. However, I did break one of the bolts when installing it, which is OK. I just switched to grade 8 bolts which is better anyways. I love the fact that Demco hitch unlocks when you pull the lever regardless of weight on it. Compared to my previous Mopar hitch you had to get at the right weight pressure to unlock it.
Seems to be built very well, and installation was fairly easy considering the size and weight. Won’t know how it travels until I get the RV in the Spring….we shall see! In my particular case, I had to use spacer washers between one of the brackets and the hitch so it wouldn’t jam in the truck mounts but no big deal.
I’ve also figured out a way to “store” the hitch for the winter.
The hitch is great. I installed it myself and it worked very well pulling a 5th Wheel Trailer across the country last year. I have learned however that one must start out from corners slower to avoid a large "clunk" as the hitch slides in the frame per the inherent design. Great Product!
Install pretty straight forward. Hitch works as it should. 90 degrees with my 5 1/2 foot bed. The ums rails..well just say there ain't no way the bolts just drop in from above like in install video. My truck is same year as in the video. Rails with spacers (which needed pusuasion to "slide" in) are flush with the bed. Also the hole plugs work great with no rails...need to trim tip off for them to seat with rails installed. See pics

Im very happy with the hitch. Ive towed for close to 15,000 miles. I did however travel over one very uneven road and cracked a weld on the adjustable side guide on the top plate. Great hitch!
