The Curt E16 5th Wheel Trailer Hitch w/ S20 Slider is rated for 16,000 lbs gross towing weight and 4,000 lbs vertical load. The sturdy, steel construction with a carbide black finish gives you a solid feel when you hook up and start down the road. It’s designed to handle heavy fifth wheels without flex or rattle, giving you peace of mind when towing through long hauls or uneven terrain.
Hooking up is simple with the auto-locking, slide-bar jaw mechanism that secures around the king pin as soon as it slides into place. A rear steel tension bar clamps down on the king pin to minimize movement and rattle, keeping your connection tight for a smoother ride. The dual-pivoting head with 10 degrees of lateral movement helps line things up on uneven ground so coupling feels natural and quick.
When you need more room during slow turns, the non-binding S20 slider gives you up to 12" of front-to-back travel. This extra clearance helps prevent contact between the trailer and cab during sharp maneuvers. The slider moves easily without binding, so repositioning is smooth even at an angle or when under tension.
Getting your trailer level is straightforward thanks to the adjustable height range of 14" to 17". These four positions let you dial in the right setup for proper bed rail clearance and stable towing performance. Once set, it stays locked in securely so you can tow knowing your rig is balanced.
Installation is simple with the included rail adapter—just drop the base into the puck receivers and pin the hitch in place. The setup doesn’t require complicated alignment or drilling, making it easy to remove or reinstall when needed. It’s a solid setup that’s ready to tow when you are.

Hello, everybody, this is Jeff at Etrailer. Today we're gonna take a look at this CURT E16 fifth wheel trailer hitch with the S20 slider and it's for the Ram OEM prep package. Has a 16,000 pound gross towing weight capacity. Now, this is a custom fit part. It is designed to fit the 2013 and newer RAM 2,500 and 3,500 trucks with the six and a half bed. And as we mentioned, the OEM prep package on it.
And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show if this will work for your application. Now, this fifth wheel hitch is designed to mount in your truck bed so that you could tow your fifth wheel trailer. It's gonna convert your Ram OEM puck system to standard rails. And this part is compatible with kingpin extension boxes, including the common pivoting pin boxes. Wanna zoom into the head a little bit here.
This uses an auto locking slide bar jaw mechanism here, which will provide superior security. The rear tension bar right here, this will work with that slide bar to clamp around the kingpin, minimizing any rattle and movement. And right over here, if you notice, there's two tabs with holes in it. It is lockable. You can lock the handle so nobody can mess with your fifth wheel connection.
And it does require a padlock, which we do sell separately. Now, the slider that it's mounted on, it is a non-binding slider, provides clearance required for short bed trucks to turn safely at slow speeds. In other words, when you release this, it'll give you a travel of 12 inches front to back on the slider. So this is gonna prevent your trailer from hitting the cab of your pickup during sharp, slow speed turns. It'll automatically latch in both directions, so you only have to exit the truck once.
And it is designed for use on trucks with beds shorter than eight feet, and it is not recommended for use on truck beds that are shorter than six feet. So basically six to eight foot range. Now, the hitch head right here does have a four position height adjustment for multiple towing applications. It'll range anywhere from 14 inches to 18 inches, and that's measured from the truck bed to the top of the hitch head. So you just put it in the position it works best for your application. The dual pivoting head right here has a 10-degree lateral movement for simple hookup, has a nice anti-rattle skid plate, provides a nice smooth quiet ride. And they do require a nylon lube plate, which we do sell separately to help prevent scratches on this skid plate, and to let your kingpin glide smoothly into the hitch during hookup. Now, it is a simple installation with the included rail adapter right here. Basically what you'll do is drop this base, and what I'm gonna do is show you, we're gonna go to a different camera angle, but you can see on the corner of this base here has these handles here. So what you're gonna do is drop the base into your puck receivers, and the way you'll do that, on each corner, you'll take out the safety pin, turn this 90 degrees, and you'll notice that tab turns on the bottom there, tab it into the open position. You'll do that on all four corners. And once you get it open on all four corners, drop the space into your puck receivers in your factory-installed prep package. And then just turn this back, take your safety pin, patch it, keep it in place, you're ready to go. And again, you'll do that at all four corners. Now, this is a sturdy steel construction. Has a nice carbide black finish. Again, the gross towing weight capacity of 16,000 pounds. The vertical load limit or pin weight capacity is 4,000 pounds. And just briefly, I wanna show you how this head operates. We have an example. This is what a kingpin would look like on your fifth wheel. So what you're gonna do is just pull your handle out and you'll notice once you pull it out far enough, it locks into the open position and now you're ready to hook up. And when you go to hook up, your kingpin's gonna slide right in. And once it does that, it pushes on that tension bar and that releases that slide bar to come across and locks your kingpin in place. And as I mentioned, if you wanna lock it with a padlock, you could do that. But otherwise just like that, and you're all ready to go. Simple to install and simple to remove. Now, if you do have any other additional questions regarding this part or any other item we carry, please feel free to reach out to us so we can help you get all of your questions answered for you. But that's about gonna do it for our look at this CURT E16 fifth wheel trailer hitch with the S20 slider for the Ram OEM prep package.

Wow--thanks for sharing your experience with the hitch! I bet you aren't the only one this has happened to, and I think you might be saving someone a lot of time with tracking down a solution. Thanks, Juan! Congratulations on the new RV, too!

Update, I still wish this hitch locked. It seems to have some slap in it. It doesnt really hurt anything, however its very noticeable when backing the trailer up. The hitch pin feels like it kind of bounces for lack of a better word against the hitch itself because of how the retaining mechanism is designed. We camp in the summer and are not full time RVers. I would not recommend this if I was a full time RVer.

I am glad to hear that everything was in tact and in the package despite the damage. The install looked like it went well, it is great to hear the videos were a big help, and it looks great in the truck. What are you planning on towing with the hitch?
