  • Fifth-Wheel Towing with Your Gooseneck Hitch

    There are a variety of adapters on the market that let you tow a fifth-wheel trailer with a gooseneck hitch. You can use a coupler adapter that replaces the pin box on your fifth-wheel trailer and then attaches to the gooseneck hitch in your truck bed. But these adapters often require modifications to your trailer that can void the warranty. Another option would be using fifth-wheel rails that mount directly to your gooseneck hitch, usually by dropping into the hitch's ball hole. But to do this you have to make 2 separate purchases - the adapter plate that has the rails and a standard fifth-wheel hitch.With the Demco Recon, you get a heavy-duty fifth-wheel trailer hitch that mounts in your truck bed by connecting directly to your gooseneck hitch with the included components. No modifications are required to your truck or trailer. And no additional parts are required for the system to work.

    Secure Wraparound Jaw with Locking Bar

    Single Dimensions

    The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the Recon hitch offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.

    A 3/4" thick solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin.

    Double-Pivot, Cushioned Hitch Head

    Head and Head Components

    The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hookup is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.

    Polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. These dampeners are built into the head assembly to cushion the head's side-to-side pivoting.

    Easy Installation

    This hitch is designed to attach to the 2-5/16" ball on your gooseneck hitch.

    Assembling the hitch is quick and easy because of its lightweight, 2-piece design. First, attach the base to your gooseneck ball. A coupler pin is installed underneath the ball and the coupler is tightened to keep the Recon secure. Then simply slide the head assembly into the opening in the base. There are 3 different height settings to choose from - just slide the head up or down to find your desired height.

    Recon detailedRecon detailed 2

    Once you have chosen your desired height, use the included pin to secure the head to the base. Finally, tighten the bolt to eliminate any movement and rattle.

Video Transcript for Demco Gooseneck and Fifth Wheel Adapters - Adapts Truck - DM8550045 Review

Speaker 1: Today we're going to take a look at the Demco Recon gooseneck to fifth wheel trailer hitch adapter. It has a 21,000 pound weight capacity. Now this trailer hitch adapter will convert your gooseneck hitch to a fifth wheel hitch, so it will let you tow your fifth wheel trailer. The base will drop just over your gooseneck ball in your truck bed. It does have a head with wrap around single piece jaw, which will provide a nice secure connection. It gives you 360 degree jaw to king-pin contact, so that will give you less rattle, more security than the slide bar jaws.If you notice in front, it has a nice 3/4" thick solid steel locking bar, to reinforce the connection with your coupled trailer.

This bar will automatically lock into place when the jaw closes. The head is a double pivot pitch head. It eases hookup, helps limit chucking. Pivots front to back, and side to side. It does use cushioning polyurethane dampeners, to help reduce your noise and absorb road shock.

The handle is a nice spring loaded handle with a comfort grip. It allows for easy, simple coupling. All you have to so is take this tethered safety pin, remove it. That safety pin will let you secure the handle in the open, or the closed position.Your spring loaded handle is you just pull it out. You pull out far enough, you can hear it locks it into the open position.

Now you're ready to hook up. Now you can use three different hitch height settings on this. When you tow your fifth wheel, you want to make sure it's as level as possible when you're towing it. This larger shank right here drops into the base. There's a pin, and a clip here.

If you pull the clip out, and the larger pin out, you can put that into three different hitch height settings, anywhere from 15 1/2", to 17 1/4", or up to 18". The hitch height is always measured from your truck bed to the top of the hitch head. Now the base also has a 3" offset. In other words, when you go to drop it onto your gooseneck ball, it does sit back 3" towards that cab. So it will move the hitch head 3" toward the trailer. It will give you 3" of clearance.This part is a study steel construction. It has a nice rust resistant black powder coat finish to it. It is a light two piece design, which makes installation or removal quick and easy. It a quick, simple installation. The hitch base, the part down here, just installs on the ball of the gooseneck hitch. The hitch head will secure right onto the part right here, and because it's a two piece design, makes it very easy to remove it. Also, you just pull the clip and pin here. Take the hitch head off. Take the base off. Simple as that.This part is made in the USA. The application, again, is designed to fit on to 2 5/16th diameter gooseneck hitch balls. Gross towing weight capacity is 21,000 pounds. Vertical load limit is 5,250 pounds. As we mentioned, the hitch height settings can be anywhere from 15 1/2", 17 1/4", and 18". The last thing I was to show you, I just want to show you how the hitch head will work. Here's a example of what a king-pin would be like on your fifth wheel. When you go to hook up, your king-pin would slide into the head, just like this. You can see, once it gets far enough back, it will release it. As you noticed, the jaw comes around. Then that locking back locks it into place.You're all ready to go. Last thing you have to do is just take your safety pin, drop it into the hole in the handle. Clip it, and you're locked into place, all ready to go, simple as that. But that should do it, for the review on the Demco Recon gooseneck to fifth wheel trailer hitch adapter, with a 21,000 pound weight capacity.

Fitted the 2008 square hole perfectly. A longer release handle with a pin locking extension would improve access. Currently, I must climb into the truck box to reach the pin & handle. Thanks. 751326

- DM8550045

I wish I had known in advance that the hitch was coming in 2 parcels and that they wouldn't arrive together, but the hitch itself is great! Assembly is simple and I can quickly disassemble into 3 pieces for easy storage in a bay. Although it states that the top plate is 15 1/2" above bed, it is actually 16 1/2" at the lowest setting and I ended up adjusting my pin box to compensate so everything rides level. All things to be expected. It is much easier than hitching up to a gooseneck, especially since my tool box blocks the view of the hitch. It rides smooth with no discernible bucking on the road. I highly recommend this hitch and especially the people that I bought it from. Etrailer has been great to deal with. Pics will follow when the weather clears. 745141

- DM8550045

From start to finish my experience with etrailer was top notch. I studied all the videos on deciding my hitch choice and more than happy. Took approx.1 hour to install completely, now ready to start using. The heavy duty quality was more than expected. Thanks again. Santa K (Kevin) P.S. ordered 2 days later on my door step 609647

Great ! A bit heavy but very easy to take out and reinstall each use as I use my bed every day. I see other hitches but for my ball to hitch application its the best.

Great product. Good price and simple ordering. 1 day shipping. Over all 5 stars. Thanks 610581

- DM8550045

Exactly what I needed, fits perfectly and works awesome!! 727365

- DM8550045

Awesome product the e trailer employees answer u immediately !!! George was super with getting me my fifth wheel !!! 567313

- DM8550045

Took about two hours to install. Of course that includes taking the old goose neck adapter off the camper. Looks nice and I will be trying it out from Anchorage, AK to Louisiana, in September. 673132

- DM8550045

Bolted right in my truck no issues everything seems to be very solid and well made 655380

- DM8550045

The hitch is easy to ensemble. Great design. Pulled my trailer great! But when I hooked up the second time to the trailer the roll pin that goes in the locking bar fell out. Wasn't a really big deal. But if I hadn't had any tools and a 1/4" bolt with a lock nut I probably won't have been able to hook up. Maybe they could change that. The best adapter from gooseneck to fifth wheel.But all in all very happy with it. 634063

I use this hitch adapter a few times a month and have had no issues with it. The paint and parts all still look brand new and it is easy for me to assemble and take apart by myself. I'm 5'3" female and can move this in and out of my truck by myself as long as I take apart all 3 pieces. I looked at a lot of adapters and this was the only one I could move myself that didn't require any modifications to the 5th wheel pin. We drive commercially and even my clients are comfortable with us using this adapter when we arrive to transport trailers nationwide. Great product at a very fair price! 625500

- DM8550045

It's a very quality piece of equipment. It clunks a little more than my gooseneck so not sure if that is supposed to do that or not and I am not as comfortable as I probably should be because I think this results in two moving parts- at the gooseneck ball and at the fifth wheel plate. I think the footprint spreads that out but without being in the back when in tow, I'm not sure if it is acting properly. It seems that starting and stopping results in a lot of banging and clanking and this after I tightened down all the bolts/nuts to proper torque. In all I'll keep it but might see about just installing the actual fifth wheel rails in the truck anyway. 570633

I installed the Demco Recon Gooseneck to 5th Wheel Hitch yesterday. The Hitch was installed on a Reese Remove A Ball Hitch and fit perfectly after cutting the rubber mat in the bed of my 2012 GMC Sierra 3500hd Duramax Diesel Dually. I will be hauling a Keystone Avalanche 5th Wheel. 628371

- DM8550045

For the most part this is a good product. i do believe there needs to be some work done on the set screw bolt that holds the height adjustment secure. mine broke the bolt off on the inside. the height adjustment began to wiggle and broke the head of the bolt off due to the nut that was welded to the outter piece broke loose. I tried to weld back with another bolt however the bolt set screw will not stay in place. i have since found my height i'm keeping it at and welded it in place. 770621

Hitch works great, easy to hook up the camper. I have a short bed truck and didn’t have any problems making turns when we drove through town or backing in the driveway. Ships out in two packages, set up isn’t a problem. Pretty self explanatory, if you’re loading or unloading from the truck either have someone help or break it down to at least two pieces. It’s pretty heavy all assembled. I would recommend this hitch versus drilling holes or welding on a gooseneck adopter to your trailer. 769648

- DM8550045

Quick setup and install. I opened the box set it up and was pulling my camper in about 15 minutes. 765643

- DM8550045

Quick shipping, box was beat up but hitch was ok. Works fine. 757196

Love the 5th wheel so far.it was easy to install might have taken 30 min just have to fine tune it. Plan on going to Houston TX in a couple of months that will be the test 500 and something miles one way. 740380

I like my new 5th wheel hitch. I especially like Demco, their factory representative can be easily contacted, unlike Reese. etrailer delivered the product I wanted in a timely manner. 725681
