Review of Demco RV Gooseneck and Fifth Wheel Adapters DM8550045

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.

The only real visual we have of this attachment comes on page 6 of the install manual, linked below. It's basically secured by a coupler bolt that gets tightened to the ball.


What keeps the base from spinning on the ball in the bed

I have confirmed with my contacts at Demco and there is a vertical bolt that is tightened on the cab side of the adapter and that adds pressure on the molded base of the interior of the gooseneck ball portion and acts a bit like a vertical anti-rattle device, and is necessary to be tightened while installed. Please it is not compatible with a rotational pin box or high rise gooseneck balls.


Can you explain how it attaches to the gooseneck ball how does the frame secured self to the ball itself. I believe this product will work perfect for me I just have that one question.

It is not very well explained in this video, and hard to visualize without a truck for installation. The base will slide over the gooseneck ball on your truck. Then there is a tightening coupler bolt that is used for securing the adapter to your gooseneck trailer ball. I have included a link to the installation instructions for your reference, check out page 6 for more details and a few diagrams.
