This hitch is rated for 20,000 lbs gross towing weight and 5,000 lbs tongue weight, giving you strong capacity for large fifth wheels. The sturdy steel construction and carbide powder coat finish hold up under heavy use and rough roads. It’s a solid foundation that feels stable from hookup to highway speeds.
The rounded, interlocking jaws wrap completely around the king pin for a tight hold that cuts down on rattle and movement. That full 360-degree contact gives you a quieter ride than slide-bar models and makes towing feel smoother and more controlled. It’s the kind of secure connection that keeps things steady even on long hauls.
A quick look at the color-coded lock indicator tells you exactly what the jaws are doing—red means uncoupled, yellow means ready to couple, and green means locked for towing. The indicators are visible from the cab, so you can check your connection at a glance before you pull out.
The fully articulating torsion head helps the hitch self-align as you back in, making hookup easier even on uneven ground. It also suppresses road shock and quiets towing noise, so your trailer tracks smoothly over bumps and turns. The included plastic lube plate lets the king pin glide into place without binding.
When you need your truck bed clear, the fast one-pin head removal lets one person lift off the top section without tools. The hitch mounts on standard above-bed rails, and height adjusts from 13" to 17" so you can dial in the right setup for your trailer. Two built-in zerk fittings make it simple to keep everything greased for long-term reliability.

Today we're going to take a look at the Curt A20 dual-jaw fifth wheel trailer hitch with a 20,000 pound weight capacity. Now, this fifth wheel hitch will mount in your truck bed so that you can tow your fifth wheel trailer. It uses the interlocking two-jaw system right here, which provides a nice 360-degree jaw-to-kingpin contact, and because of that it'll give you less rattle, more security than your slide bar models. Also, on the front of each jaw, over here and over here, you can notice there's two built-in grease zerk fittings, which will give you easy lubrication of the jaws. This hitch does use a fully articulating torsion head for controlled coupling and a nice stable, quiet ride. It will self-align for easy hookup, and helps suppress road shock to reduce any bothersome towing noise. The handle right here is a lockable handle.
It's a very short-throw single-handle operation. The nice thing about it, also, it does self-reset to the ready-to-couple position after uncoupling. Now, when you put this together, when you mount the crossmember to the legs, there's three rows of holes on the crossmember, so it actually will give you a four inch hitch height adjustment. The hitch height would be measured from your truck bed to the top of the hitch head, and you want that to be as close as possible, so when you're towing your fifth wheel with your tow vehicle, you want those level. It gives you three choices, anywhere from thirteen inches of hitch height adjustment up to seventeen inches. One of the nice features on this is the three-point indicator system. It'll tell you what position the jaws are in.
What's nice about it is that it's color-coded. Let me just swing this around so you can be able to see. If you notice, right under the hitch head, right here, you'll notice right now it's showing solid green. That means the jaws are completely closed. If we had a kingpin in there, the green would mean you're ready to tow.
This color coding will tell you if the hitch is ready to uncouple, couple, or tow. What's nice about those colors and looking, if you're in the cab, the cab would be right here, you can turn around as you're hooking up or uncoupling and watch the color, and when it changes, it tells you the position of the jaws. Basically, the green, like it is now, the jaws are locked closed; it's safe to tow. If it goes to yellow, let me just unhook this and pull out the handle. You can see right now, because I opened the jaws, it's showing yellow. Yellow means the jaws are ready to couple.
It's safe to back in the truck to couple up to your fifth wheel. It if would show red there, that means the jaws are locked open, and it's safe to pull your truck away. When it's red, you do not want to couple. Also, this has a nice fast one-pin head removal, makes it very easy for one person to remove the hitch. Back here, there's a clip you can pull out, and then you can pull this large pin out, and that'll allow you to take the head out of the crossmember so you can take it apart in pieces, which makes it easy for one person to remove the hitch. Also included with this . Let me roll this around here. There we go. Included with this, I have laid out, comes with the plastic loop plate right here. This plastic loop plate will go onto your kingpin and lets the kingpin glide smoothly into the hitch during hookup. Also comes with, you can see, the pins and clips for attaching the legs to your base rails. This is a simple installation with base rails and an installation kit. Now, the base rails and the installation kit we do sell separately on our website. I would recommend to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you the correct base rails and installation kit for your application. This fifth wheel hitch is compatible with B and W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley above-bed base rails. This is a sturdy steel construction with a durable carbide powder-coat finish. Again, the specs on this. The gross towing weight capacity is 20,000 pounds. The vertical load limit or pin weight capacity is 5,000 pounds. We had mentioned the hitch height adjustment from thirteen inches to seventeen inches. What I'm going to do now is, we already have the jaws open, ready to couple, showing yellow, so what I want to do is here's an example. This is what a kingpin would look like on your fifth wheel. When you go to hook up, your kingpin would slide in between the two jaws, just like this, and once you get it far enough, your jaws will completely wrap around the kingpin. You notice the handle automatically slides up. The holes line up, so you just take your pin and clip, drop your pin into the hole, clip it, and that'll lock the handle. Now, the hole is large enough, you could actually put a padlock on there if you wanted extra security. It does come with this attached pin and clip. With the handle locked, you look back here at the color, it's showing green. That means you're all ready to tow. Again, to uncouple, you just pull your pin out, open it back out, and go, be able to back right out. That should do it for the review on the Curt A20 dual-jaw fifth wheel trailer hitch with the 20,000 pound weight capacity.

Sorry to hear about the damage and difficulties, Jeff. The handle will get easier to actuate with use as they can be on the stiff side when new. I don't recommend beating it with anything as that will probably damage the mechanism. So don't do that. Are those B&W rails in your bed? And what do you carry in your toy hauler?

Still have not heard from your customer service on why it so difficult to separate the two sections of my hitch.
