Review of Curt Fifth Wheel C16566


Today we're going to take a look at the Curt Q25 Dual Jaw 5th-wheel Trailer Hitch with the R24 slider. It has a 24,000 pound weight capacity. Now this 5th-wheel hitch will mount in your truck bed so that you can tow your 5th-wheel trailer. It comes with the non-binding slider, which will provide 12 inches more clearance which is required for a short bed truck to turn safely at slow speeds. That'll help prevent the trailer from hitting the cab of your pick-up during those slow speed turns. It does slide smoothly on these rounded non-binding rods. The slider is designed for use on trucks with beds that are shorter than 8 foot.

It's not recommended for use on truck beds that are shorter than 6 foot. The head has a nice 2 jaw locking system which provides a full 360 degree jaw to kingpin contact, because of that it'll give you less rattle, more security than the slide bar models. On the head there is 3 lube points and they're easy to access. One right down here, one over here and one over here. They are Zee Grease zerk fittings which will allow you to pop your grease gun right onto them and pump them full of grease for lubrication. Now the hitch height adjustment. This gives you a 4 inch range and the hitch height is measured from your truck bed up to your top of the hitch head.

That's critical because you always want to tow your 5th-wheel trailer as level as possible with the tow vehicle. When you go to mount this cross member to your slider legs, there's three rows of holes that will give you the option of a 4 inch height adjustment, anywhere from 20 inches hitch height up to 24 inches. The head itself, it's based on a unique spherical axle bearing which allows easy pivoting of the hitch head. Gives you a nice smooth 360 degree movement, not just front to back and side to side tilting. Also has built in cushioning to help absorb any road shock. The main feature on this is the three point indicator system. Basically what that is it's a color coding that you will tell you if your hitch is ready to uncouple, couple, or tow, and it's on the back of the handle right here.

It will show a color that's visible from the cab, so if you're in the cab here looking back as you're hooking up, you can tell by what color is showing in that window what position the jaws are in. What I'm going to do is just turn this around to show you what we're talking about here. There we go and you can see right in here there's the window. It has the color in it. Right now you can see it's showing green, and green means you're ready to tow. Basically that means your jaws are completely wrapped around the kingpin.

Now we don't have one in here, but if there was one in here, it would be completely wrapped around there. You're ready to tow, it's all locked, ready to go. If it shows yellow, let's unlock this handle, and we'll open it up. You pull the handle out and the jaws pop right open. Now it's going to show yellow. Yellow will mean the jaws are ready to couple, so it's safe to back your truck and hook up to your trailer. Now if it did happen to show red in there, there's just three colors. Green, yellow, and red. If it showed red, red would mean the jaws are locked open. It's safe to pull your truck away, but it's not in the position to couple right now. This handle, if you notice, it is a lockable handle. Just flip this over to lock it and put the pin and clip through there. It is a short-throw, single-handle operation and the nice thing about this handle it will self reset to the ready to couple position after uncoupling. Also while we have it turned around if you notice these two pins right here with the clips on them. If you pull those out, pull the clips out, pull the pins out, you can actually take the head out of the cross member, and that's handy because it makes it easy for one person to remove the hitch from your truck by taking it all apart in pieces. What I'm going to do now, let's swing this back around. Now this does come with everything shown here. Comes with this included plastic lube plate that goes on to your kingpin so when you're hooking up it will help that kingpin glide smoothly into the hitch during hookup. Comes with four pins and clips that you put through the slider legs to attach them to your base rails. For this video I'm displaying it on base rails and an install kit. But now when you do receive this, you do have to still purchase the base rails and the installation kit for your application. We do sell those separately on our website. It is a simple installation. What I would recommend is to go to our website, use our fit guide, put in your year and model vehicle, and it will show you the correct base rails and install kit to attach this to your vehicle. These slider legs here are compatible with BMW, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley above bed base rails. The hitch is a sturdy steel construction. Has a nice durable carbide powder coat finish over it. A few specs again on this. The gross towing weight capacity is 24,000 pounds. Vertical low limit is 6250 pounds. The slider travel from front to back is 12 inches. The hitch height we mentioned is adjustable from 20 inches to 24 inches. What I'm going to do now is I want to demonstrate the jaws and the hitch head how they work. Then how the slider would work. Let me grab a sample of a kingpin. This is what a kingpin would be like on your 5th-wheel. Basically we have the jaws already open. We pulled the handle out. It's showing yellow means you're ready to couple. As you're backing up and it's hooking up your kingpin is sliding in. Once it gets in far enough, the jaws as you can see will completely surround the kingpin for 360 degree contact. Then if you look where the color is in the window, it's showing green. You're already to tow. All you have to do is flip that over, line the holes up, put the pin and clip through, and the handle's locked. You're ready to tow. Then if we're ready to uncouple, just reverse it. Unlock it, pull the handle out. It will let the kingpin come out of the jaws. Now that you're all hooked up there, I'll show you how the slider works. This handle, which would be on your driver's side of your tow vehicle. Right now it's in the towing position which means it's closest to the cab. Your cab is back here, so this would be the closest to the cab. When you're on the highway, and not making sharp turns you're fine. But if you get into a campground, and you're having to back your trailer in, you might have to do some sharp turns, you don't want that trailer hitting the cab, so you want to gain an extra 12 inches back to the maneuvering position. Take this handle, and pull it out and just rotate a little bit to hold it open towards the cab. That will hold it in the open position. Then you will see it slide to 12 inches, and once it gets to the maneuvering position, it's locked automatically into place. Now you have that extra 12 inches of clearance, so the trailer doesn't hit your cab. When you're done maneuvering and you want to get back on the road and tow, you want to put it as close to the cab as possible. Same way, take your handle, this time just turn the handle towards the 5th-wheel, that will lock it in the open position and slides back in to the towing position. Just like that, and same way. It slides it over and locks into position. Now you're all ready to tow. That should do it for the review on the Curt Q25 Dual Jaw 5th-wheel Trailer Hitch with the R24 slider, and a 24,000 pound weight capacity.
