Features to know about

Built to Tow the Big Loads: 31,000 lbs Gross Towing Weight Rating

This hitch is rated for 31,000 lbs GTW, making it the highest capacity setup in its class. It’s built from solid steel with a corrosion-resistant powder coat finish and uses heavy welded components that feel rock-solid under load. The one-piece wraparound jaw and 3/4" thick locking bar reinforce the connection so you can pull massive fifth-wheel trailers without worrying about flex or slop.

Secure, Stable Connection: Wraparound Single-Piece Jaw with Locking Bar

The wraparound jaw completely surrounds the king pin for 360-degree contact. That tight fit means less rattle and more security than standard slide-bar designs. When the jaw closes, the solid steel locking bar automatically snaps into place, adding an extra layer of protection against accidental uncoupling. The result is a quiet, confident hookup that feels tight every mile down the road.

Smooth, Cushioned Ride: Double-Pivot Head with Polyurethane Dampeners

The double-pivot head moves both front to back and side to side so it naturally follows the trailer as you drive. Three polyurethane dampeners absorb shock and reduce noise from road bumps or trailer movement. Together, these features help cut down on chucking and make towing feel smoother and more controlled—especially on long hauls.

Quick Drop-In Setup and Easy Bed Access: OEM Puck Mount Design

Installing this hitch takes just a few steps—bolt the side plates to the base, set your height between 16" and 19", and drop it into the four receiver pucks. Turn the handles to lock it in place and secure with the safety pins. When you want your bed clear, pull the pins, twist the handles, and lift it out. The head removes separately—about 40 lbs for that piece and roughly 160 lbs for the base—making it easier to handle without equipment.

demco hitch is as nice as the auto slide demco i had built heavy, works great, and fit the factory pucks on my gmc perfectly.thanks



by:

Not to difficult to install. It will require 2 people to get the bolts torqued down. Handles a 14000 lb fifth wheel with ease



by:

Can't say enough good thi gs about e-trailer has worked with me, in turn I and my family have purchased many items. My hijacker hitch works perfect.



by:

I haven't towed with this hitch yet so I'll update this when I do. Shipping was faster than I expected. It shipped in two boxes and both arrived at the same time and in good shape. Assembly took about an hour and was pretty straight forward. The included instructions are a bit vague but if you have just a little bit of mechanical knowledge and some tools its easy to figure out. I couldn't find any torque specs in the instructions but after doing a little research on the internet I found there isn't an actual spec, only make sure the bolts are good and tight, but not overly tight.



by:

Have pull our 42' Montana 5th wheel trailer a few times and this hitch is working great.



by:

No chucking at all, easy assembly and maintenance. Drops in and out of the brackets easily and the latching handles double as carry handles. Weights a lot, and comes in multiple boxes, so be sure to tip your UPS guy!

The bolts are all grade-5 hardware and torque should be standard based on diameter.



by:

This hitch assembled quickly and installs easily. Many thousands of miles and zero issues. I would highly recommend ths hitch. Mush smoother and problem free than my prior hitch.



by:

Hitch is nice and makes me feel more comfortable being a more novice RV'er with the large steel bar that acts as a secondary safety, unlike one of the other big brands that just has teeth that close around the pin. Assembly took a couple hours of blood and sweat even though it really is very easy.... You have to make time to torque about 20 or so bolts, but that's pretty typical of anything you plan to drop up to 21k pounds on and jerk around all over the country. Install into/out of the truck bed is now a 5 minute project thanks to a block and tackle in the garage ceiling. Extremely easy to put in or remove as long as you have an overhead weight bearing device of some sort. Beyond my experience with dragging a 17k pound RV with it, the mfgr is VERY responsive if you call for help. I was missing 1 washer upon assembly and the sticker decal was damaged in shipping but the MFGR had new ones in my mailbox in 2 days at no charge. They are also VERY good on tech support. The only caution I have on this is make 100% sure you know what grade bolts you have and what you should torque them to. Novice mistake: I rated the bolts based on the chart in the instruction guide but I rated on head size, not the diameter and thus I over-torqued. Luckily I did not have the means to torque to the actual higher spec or I would have snapped them at 250ft-lbs. If you have any questions on correct torque, call the mfgr and as for tech support! As for usage experience: Carry a long stick with you. We end up on crooked camping sites frequently and the only issue is that while this hitch moves ALOT to accommodate, sometimes you may get up under the pin-box and you just can't get the hitch to snap shut. Having a long stick on-board will let you push on the spring-loaded part and cause it to snap closed. One last thing from experience: lube, lube, lube. Keep the thing lubed as per the manual and do not be stingy with it on the parts that slide and grab your king-pin. It helps out drastically in getting it to snap closed on the 1st try. As for lubing the top plate, everyone is using those plastic lube discs these days. They work fine BUT: They WILL cause you a bit of grief in getting the pin exactly where it needs to be to snap closed on occasion. The hitch has enough wiggle room to accomodate them but it is not 'designed' for it, so once you're 1/4" higher out of the hole than spec, sometimes you will have to play with it to get it shut. If you ever find yourself just TOTALLY unable to get it to close on the pin, put your jacks back down and pull out from under your trailer. I totally destroyed one of those plastic discs a week ago and spent 40 minutes fighting and cussing at the thing b/c it wouldn't close on my pin far enough to put the safety pin in the handle... I finally yanked the hitch out from under the trailer and I had caught the lube disc at an angle on the 1st try and it had ripped a gash in in. That extra misplaced material up under there was preventing me from being able to secure the pin. Aggravating: Yes. But I kinda like it. You will KNOW that there is an issue with your current hitching job with this thing. It can be unforgiving at times but when I have $80k of truck and $110k of RV depending on it, I'd rather it be unforgiving and tell me in a loud voice: "You screwed up your mount attempt, try again" than to get to the end of an entrance ramp and have the trailer come down on the truck bed. If I had to buy one again, I'd buy the same one.



by:

This is better than I thought it would be. It came in three boxes and you have to put it together but the instructions are easy to follow. It is totally height adjustable so you don’t have to worry about whether it will be too short or too tall for your truck bed.

Second product I bought from etrailer with no complaints.



by:

Great unit and help from etrailer. We sold the 5th wheel that had a sidewinder hitch on it. We are buying a 2017 Keystone Cougar RLSWE now. Will this Demco work on it?
Thanks



by:

Very simple install. Very well built unit. Had to remove 1 shim on 3 of the feet because the handles were way too tight. Had ro use a rubber mallet to turn them at first. After removing the shims, it is perfect. I purchased a small master lock to replace one of the cotter pins for the safety pins so that noone steals the hitch. No noise while driving with just the hitch installed at all. I have not had a chance to tow anything as of yet--- pick up my 40' 5er wed!
Seems to be a very well made, good looking, compact hitch. This was installed in a 2018 F350 long bed dually woth the oem under bed puck system.



by:

The safety features of this hitch were exactly what my husband was looking for. We have a 2016 F 350 with the factory cutouts and this dropped right in and locked in with no problems. You do have to put this together which is fairly simple. The only complaint I had was throughout shipping, there were holes ripped all throughout the boxes. One of which was the one that had the nut's bolt's and washers in it and they weren't sealed in the bag that they came in so, we didn't have all of them. Many were lost but they were easily replaced at the local parts store.
We haven't towed with it yet but everything should be typical with that.



by:

Our Demco hitch installed with out issues. We didn't use it till the last of May, then we pulled over 3000 miles. the only issue we had was un-hitching with hitch & 5th wheel in a semi-bind, NOT the hitches fault. Totally satisfied with the unit.
We have had Demco tow bars for years before our 5th wheel, so we were not surprised at the quatity of our hitch, only complaint would be better prep before painting/coating unit. thank you Phil Z



by:

Hitch went together smoothly and fit into the factory bed holes perfectly.Rides nice on the initial test drive.Demco could make their packaging more durable. the paint was rubbed off in one area and the box was on it's way to destruction. let's face it, this is some heavy stuff to ship around.



by:

This hitch did amazing with a trailer move i preformed over the weekend..Demco products are highly recommended.



by:

The Demo hitch arrived first, all good, nice heavy duty boxes, I assembled it with no issues, can't wait to use it.
The Hydrastar disc brake kit however arrived a couple days later in a beat up torn box barely held together. The parts in the big box were also boxed sort of, they were all broken and torn up. Fortunately the parts weren't broken.I have never seen heavy items with such flimsy packaging. I assume hydrastar boxed it all up. I am giving 5 stars because Etrailer has great customer service, and helped me over the phone to make sure I was order the correct items for my rig.



by:

This is one of the best fith weel hitches that I have had and I used about all of of them thanks for thanks for asking



by:

I am HAPPY 5TH Wheel



by:

Other than the logo sticker being upside down the hitch is great. Demco is sending a new one. No problem to assemble and install. Regarding etrailer.com, what rating is above excellent? Pat C in customer support went above and beyond to address any issues and was always ready to answer any questions.



by:

First, thanks to Christina for the service and information re hitches and selection.Ok now for the complaints..... they are few. THE instructions are poor at best and the description details are misleading. They state no drilling required other than the truck bed. While I am sure this is true for 2010 trucks and newer, not so for my2007 F350. Not stated in the description is the fact that older trucks require 4, 1\2 inch holes need to be drilled in the truck frame rails. No big deal but be prepared to drill them if your truck is an older mod. Ford.
Came in four boxes, each with its own set of instructions... What I was looking for was a Start Here point. That didn't exist so it was guess work for a starting point. Referring back and forth to different sections for what to do.
Once I got past the slight confusion ,assembly and install was pretty easy.
Took about 4 hours start to finish. Haven' towed with it yet..... that happens later to day.
Good stuff. The hitch is well made and Quality seems to be outstanding. It works just as expected easy to place the hitch in the truck and comes out easily too nice clean bed after removal.
If it weren't for the instructions this would be 5 star rating.



by:

Looks like a great hitch, just put together and it fits great.



by:

It seems like a good hitch we still have snow up here so I have too wait to try it out.everything fit perfect. I think I will be very happy with it, and it was at a good price as far as I’m concerned. If someone is thinking about getting one just remember you need a torque wrench.



by:

Having owned and used the 2005 predecessor to this hitch, I can say it's done well for us. I am hoping that this new clamshell design will make connecting to our 5th wheel toy hauler even easier. We've never invested in a hitch cover for the old one and only travel about 5 times per year. The hitch is always in the weather. We plan on covering this one as the rain washes away vital lubrication and the sun evaporates said same. This has made operating the old slide bar type hitchhiker a pain from time to time. I was disappointed in the packaging for shipment. There were three separate cardboard boxes, two of which had parts either penetrating out through the sides or in the one case, a bag of bolts falling out upon delivery. I would have liked to see better operating instructions included in the box. There are parts lists and schematics for each of the separate assemblies, but nothing aside from the stickers on the hitch on how to properly use and maintain the hitch.

  • Comparing B&W Companion, Curt A25, and Demo UMS Jaw Systems for 2022 Ram 3500
    Great question, Jason. The jaws on the BW Companion # BWRVK3600 don't overlap like the A25 # C16046, but they are a massive 1" thick and have never had a problem keeping hold of the king pin. I personally like the jaw system of the Demco UMS # DM67GV the most because of the single jaw with that extra piece to keep it centered as well as the 3/4" bar just for peace of mind. All 3 of these 5th wheel hitches are top-notch and provide great performance. Although I like the Demco design a...

  • Can Older Demco FWH 24PA 5th Wheel Hitch Be Adapted to Fit 2024 Ram 3500 OEM Puck System
    Thanks for reaching out, Mark!

  • Fifth Wheel Hitch Recommendation for 2018 Ram 2500 that is Smooth and Quiet
    A lot of people refer to the B and W Companion hitches as the gold standard of fifth wheel hitches so you can't go wrong with the part # BWRVK3600. What people rave about this hitch is how quiet and smooth it is as well as how well it's proven itself over the years as being super reliable. The only other hitch that rivals it is the Demco UMS part # DM67GV which also is knowing to be really quiet and smooth. It's a newer design so it's maybe not as proven but it's jaw design, cushioning...

  • Recommended Lube Plate for a Demco UMS Double Pivot 5th Wheel Hitch
    I sure can Alex. For your Demco UMS Double Pivot 5th Wheel Hitch item # DM67GV, I recommend the 12" diameter Curt Lube Plate for 5th Wheel Trailer Hitches item # C16722. Demco does recommend using a lube plate that is not thicker than 3/16" or grease on the skid plate. The Lube Plate item # C16722 is going to be a lot cleaner than adding White Lithium Grease like item # L11354 to your Demco item # DM67GV hitch head.

This will extend the life of the hitch and cuts down on the noise without the annoyance of getting grease all over the hitch and king pin.
