Review of Curt Fifth Wheel C16536


Today we're going to review part number C16536. This is the Curt Q20 5th Wheel Trailer Hitch with the Curt R20 Slider. This is a Dual Jaw design hitch and has a 20,000 lbs weight capacity. Now, for demonstration purposes, I have this mounted on some base rails just to give you an idea of how this would install on your truck bed. Now, this is a 2-Jaw locking system right up there which will provide 360-degrees jaw-to-king-pin contact. That will give you less rattle, more security than some of the slide-bar models. The head on this is a unique spherical axial bearing which allows easy pivoting of the hitch head.

Gives you a smooth, 360-degree movement, not just front-to-back and side-to-side tilting. It does have some built-in cushioning absorbs road shock. Now there's also 3 Lube points on this hitch head. On each side there's a grease zerk fitting. Right in the middle there's a grease zerk fitting so you can actually lubricate the points on your hitch head that move to help give it longevity. Now, this is on a non-binding slider which will provide clearance that's required for short-bed pickups to turn safely at slow speeds.

That'll prevent the trailer from hitting the cab of your pickup during sharp, slow-speed turns like when you're maneuvering in your camp site. It does slides smoothly right here on this rounded, non-binding rods. Now, the sliders is designed for use on trucks with beds shorter than 8'. Then it is not recommended for use on truck beds that are shorter than 6'. The handle right here, you can see, has a lockable handle right here, lets you easily secure your trailer to the hitch once your kingpins in. Has a pinning clip that's included.

That you can just pop the pin and clip off. Lets open this latch and then you can open the handle. It's also big enough, the holes are, that if you put this across you can actually use a padlock in there. A lot of people might, for additional security. Run a padlock through there, now the padlock is sold separately on our website. This is a short-throw, single-handle operation.

Basically, if you just take the pin and clip off, leave the latch down. I'm going to show you, I got an example of a kingpin here, but if you just push, pull this handle, it's, there you go. Pull it all the way out, you can see it'll lock into the uncoupled position. Got the kingpin out of there. Now, it's uncoupled, ready to be coupled. What you got to do is just lift up on this latch. When you do that it'll drop down to the couple position. Now it's ready for the kingpin to slide in there. Once it slides in there, given example, this is an example of a kingpin. Now, it's set up to when it's slides in, it'll push back on those jaws. When it does that it'll drop the handle into the lock position. Then you can put your pin and clip or padlock if you decide to use it. Right back into place. This is a self-aligning head which will pivot for simple hookup. Now, it does come with this plastic lube plate that you can put on your kingpin. What that will allow you to do is once it's on your kingpin on your pin box, helps slide on to their and gives you some lubrication between the hitch head and the kingpin. It also come with sound dampeners that, those have already installed, basically it's a square rubber piece with a hole on the middle. That you would put those between the rails and these legs of the slider. You put those on the tabs that dropped into the rails. What that'll do is to give you a rubber cushion between the rails and the legs of the sliders so that'll give you less rattle. Now, also this center cross member, on the ends here, there's actually three rows of holes. You can see there's two bolts on each sides. Depending on, if you raise that cross member into whichever the level of holes you want. You can actually get a 4" range of height adjustment. That's for your hitch height which means the measure in from your truck bed to the top of your hitch. You want to try and get that as close to perfect as possible. You'd, by changing the cross member on those three rows of holes, the range will be anywhere from 17 1/2" to 21 1/2". Now, I do want to swing this around to the back. Just to show you a few features on the back here of the hitch. With this all the way turned around, you can see there's actually 2 pins and clips right there. Basically, that lets you and allows you to remove the head. Makes it easy for one person to remove the hitch. If you're done towing and you want to take this out of your truck bed, if you try to take the whole unit out it's pretty heavy. Even it's heavy for two people. The cut down on that, what you can do is you pull these two pins and clips out on one side, the same on this side. It'll allow this head to come out of the cross member so it lightens it up for one person to do it. Go ahead and put that back in. Now, there's also back here right on the handle, you'll see some colors. That's actually a three point indicator system. The color coding on this makes it tells you if your hitch is ready to uncouple, couple, or tow and these colors, these indicators are visible from the cab so when you're in the cab, you'll be able to see when you hook up if it's ready to couple or if it's locked in to the two position. Just to show you that again, we'll take the pin and clip out. Again, right now, you see the king pins installed and it's showing green, so that means it's locked, ready to be towed. The green would indicate tow position. If we just slide this, again, if I just pull this out all the way, king pin comes out. You can see now it's showing red. Red means that it's in the uncoupled position, the haws are open and it's uncoupled. If you drop this, if you just lift up on this, that drops it to yellow. You'll see the yellow in the window there, that means it's coupled. Now, it's available to where the jars are ready when the king pin drops in there, it would wrap around the king pin. Just to show you that, like we did earlier, if you watch that color right now it showing and if you're in the cab of the truck, you'll be able to see when you're backing on the king pin, it's yellow, which means it's able to couple. Once the king pin comes in, you can see the jaws wrap around it, locks in the position, and shows green, green means you're ready to tow. All you have to do is put your pin and clip, and position, locks the tab in, locks the handle, the king pin's all locked up, ready to go. There are also, when I spin this around, I'm going to show you how the slider works. There's a color line on this slider handle over here and one over here. The green is over here and red is over there. That also indicate if the slider is locked in position or not locked. I'll show you that in a minute here. Let's swing this back around. I had mentioned, for demonstrations in this video, I got it mounted on some rails. Now, the rails, the base rails and the installation kits, which are the mounting brackets that go to the frame of your vehicle on the side here. These are all sold separately. We recommend just go to our website, put in your year and model vehicle and it'll show you the choices you have. This hitch will work with industry standard rails made by Curt, Draw-Tite, Hidden Hitch, Pro Series, Reese, and Valley. I do recommend that if you go to look up your base rails and installation kit, that if there is a vehicle specific bracket kit available for your application, we highly recommend to do that because it will simplify the installation probably about half the time as a universal kit. Now, it's not available for all applications but the popular ones that is available so far, we do highly recommend that. The hitch is made of a sturdy steel construction. Has a nice durable carbide powder coat finish. Gross towing weight capacity on this is 20,000 pounds. Vertical load limit or pin weight capacity is 4,000 pounds. I did mention the height adjustment you can set is anywhere from 17 1/2" up to 21 1/2". The slider has 12" of movement, front to back. Just to show you how the slider works, if you pull this handle right now, it's in the locked towing position. Let's turn it just a little bit so you could see. There's a green here, that's the locked towing position, which you want to do, is when you go to, if you want to go to maneuvering position or where you'd get to your campground, you want to maneuver in the sharp, sharp turns in a small area. You want the maneuvering position, you wanted to go back further to the tailgate. What you'd do is pull out on this handle, just like this, and then you'll turn it counter-clockwise, push the handle towards the cab of the vehicle or counter-clockwise. Now, that will allow this to unlock and you could see the red showing right now, that means it's unlocked. So if you go, this will slide to the maneuvering position. You see there's a little cut out here, when it hits that area, which is 12", the handle will automatically slide over and lock and it's no longer showing red. But over here, it will show green. On the pin, green is sticking out so you'll be able to see that. Now, you're locked in a maneuver position, you can maneuver your trailer into a campground where you need. Now, if you're all done camping and you're ready to go, what you can do is unlock it from the maneuvering. Now, when you do the unlocking from maneuvering, what you got to do is pull it and go clockwise. If you're going to go to maneuvering, it's counter-clockwise, if you're going to go to towing, you put the handle clock, or clockwise. What it'll allow you to do, is this will slide all the way back towards the cab in the towing position. Same way when it hit that slots in there, that groove. Handles slides in, red is no longer showing. If I turn this you'll probably able to see the green. There's the green ring showing on the pin right over here, it means it's in the lock position so you're good to go. That should do it for the review on part number C16536. The Curt Q20 5th Wheel Trailer Hitch with the Curt R20 Slider, the Dual Jaw Design and the 20,000 Weight Capacity. .
