Secure, Two-Piece Jaw

Q20 Two-Piece Jaw

Unlike slide-bar models, the rounded, two-piece jaw on this fifth-wheel trailer hitch inhibits rattle and movement by securely wrapping around your trailer's king pin, resulting in easier hookup and a safer, quieter ride.


Three-Point Indicator System

Get peace of mind with Curt's color-coded lock indicator. Just look at the indicator - either the one on the handle or the one on the hitch itself - to determine whether the jaw is in the correct position to uncouple (red), couple (yellow) or tow (green).


Q20 Color Indicator System

360-Degree Pivot

Curt's unique spherical axial bearing provides a durable pivot point that allows easy, 360-degree movement of the hitch head. This ball joint is designed for smooth, quiet operation with less clunking and chucking.


R20 Slider

Most often used on trucks with 6' and 6-1/2' beds, this roller helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a roller to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


Non-Binding Design

The round-tube design of this slider allows for relatively uninhibited movement of your fifth-wheel hitch. Because your hitch can glide smoothly and easily along the rods, there is less chance of binding.


With straight, flat contact points, as found with square-tube sliders, tension can build between the slider and the hitch when your truck and trailer are somewhat out of line or are on uneven ground. As a result, it can be difficult to properly activate the slider when your truck and trailer are not in a straight line.


With a round-tube slider, there is more give between the contacting surfaces, allowing better mobility of the hitch system. Fewer corners means less tension buildup. Activating a round-tube slider is easier, and operation as a whole is smoother.

Ordered via phone on a Wednesday. Was delivered on Friday. Ordered the slide that is compatible with my puck system. Came in three boxes. All parts and accessories were accounted for. Only issue was directions supplied was for the rail system. But, online video’s are out there to help with product instillation. Hitch is easy to connect and disconnect from king pin. Pins instead of bolts would make it easier to adjust the height but, once it’s set for your king pin, you are good. So measure first before you assemble the head. 821444

eTrailer did a great job with packaging this product with the factory OEM packaging inside additional reinforced boxes. The large heavy packages arrived in good shape. I had to return two of the same hitches I had originally ordered from Amazon because they were shipped in original OEM packaging with no extra packaging and arrived in poor shape with significant damage to the hitch. Overall very happy with the quality and performance of the Curt hitch. I installed a electric winch in my garage for easy removal and installation due to overall assembled weight of hitch. (Too old for lifting heavy objects or smarter with age?) 820999

Just installed today, all parts are very heavy. I will need a crane to take it out. Had to go to hardware store because of some wrong parts in sealed bags. Handle was bent my guess was during shipping. Maybe a little to early for a complete review. Looking forward to hooking up the trailer and testing hitch. 670303

Review from a similar Q20 in Fifth Wheel Hitch


The Curt Q20 with R20 slider hitch arrived just as promised in 3 days after placing the order. The Q20 head box was totally destroyed. The manufacture packaging was not made to ship individually using small package carrier such as UPS. Upon inspection I discovered that the bolts and washers were missing. I contacted Bill at E-trailer and told him. He explained that the replacements would have to come from the manufacturer and would take several days. I told him that I already scheduled an install and really needed those bolts and washers. He was able to round some up for me and shipped them out next day and they arrived on Monday just as promised. I also spoke with Bill about not being able to remove the head unit for the hitch. It needed to be removed to be able to install it on the slider. It seemed to be stuck and I could not budge it. I assumed that it may have been damaged in shipping, especially after receiving it in a demolished box. He explained to me that since it was new its tolerances were tight and I might try taking a pry bar to it. Well that did not make me feel real good. He was totally correct. Just a little more effort with a pry bar moved it just enough for the bushing to squeak loose and the head came right out. I am disappointed in the jaws on this unit. They look like they were forged by a 3rd grader. Not smooth and somewhat pitted. They are not machined jaws for sure. Had it all installed using the new Reese rail brackets for the 2017 F250. Everything went smooth. An added plus is the quiet ride when not connect to trailer. Can’t even notice the hitch is back there. My other hitch rattled and clanked all the time and was so annoying. I just hooked my 38ft 5th wheel for the first time. It was smoother and easier than any other hitch I have ever used. I bought the sider unit which is recommended by all for the short bed. However I cannot use the slider as the king pin box slides too close to the tall tail gate. The new 2017 F250 is taller and the bed is deeper so I needed a hitch that would go up to 19 ½ inches. I will update after a my first run with trailer later this month. Everyone at E-trailer was outstanding. 5 Star. I will keep using them in the future. 303415

Review from a similar Q20 in Fifth Wheel Hitch


I had a 16K Husky 5th wheel hitch for 12 years. It came with the RV purchase. We upgraded to a larger 5th wheel in 2015. I pulled it with the K16 but due to wear on the hitch I didn't feel comfortable. I searched the internet and came upon etrailer.com. I began researching different hitches. I settled on Curt due to it's reviews. I placed an order with etrailer and the next day I got an email with all of the shipping and tracking information. I had the hitch in 5 days. I was very disappointed when it was delivered. The shipping box was very light duty and had been reinforced with pieces of cardboard damaged. There was also a lot of heavy duty staples holding it together. I took photos upon delivery. After I opened the box I found the hitch was damaged. I immediately sent an email with photos of the box as received and the damage to the hitch. I called customer service and talked to Gina and Janice and went over the details. I was given instructions for returning the hitch and was emailed necessary papers to ship it back at no charge. I dropped it off at UPS the same day and received notification in 3 days that it was received. I was also advised a new hitch would be sent out and I received it in 3 days. At first I was very upset but after. That quickly changed after talking to the staff and receiving the new hitch within 5 days. These type things sometimes happen. I give the staff at etrailer.com an applause for their quick handling of this issue. I have since made another purchase. Give them a try. 275867

Review from a similar Q20 in Fifth Wheel Hitch


Just got back from a two-week road trip out west, the new trailer hitch performed without a snag! Easy docking and undocking, very nice to have a nice smooth ride. We are very impressed and thankful for an excellent product. The package in which the hitch arrived was in pretty rough shape, but all the pieces arrived. There is one place on the deck itself where it took some scuffing of the paint from whatever it was banged on during shipping. We are going to have to touch up that place to keep it from rusting in the elements. All in all, this was a great buy. Thanks 574834

After watching a YouTube video, assembly wasn't a problem. Hitch seems ok, haven't used it enough yet. The one problem I Have at this time is the Curt decal on the hitch head was installed crooked . It looks like a kid put it on. If I can't get another one I'll tear that one off and repaint if needed 634939

Received product from ETrailer in a very timely manner. All went well with no hitch, play on words, that is what I purchased. Sandy was helpful beyond belief and answered all my questions. Some speak of the damaged boxes when these Curt Hitches arrive. Mine too were damaged but the product was unscathed. Shipping the 100 lbs products I didn't expect the boxes to last. ETrailer did a great job stuffing the shipping boxes all was well. I would recommend ETrailer just on how professional the employees are. I will being purchasing other items again. Thanks again Sandy! 328914

Review from a similar Q20 in Fifth Wheel Hitch


After I bought my new camper the search was on for a better hitch. I previously owned a little rocker 15k with the slide bar style locking mechanism. It worked well but with the bigger camper I wanted something that would eliminate the chucking in the hitch that I was getting. After looking at a lot of other hitches and comparing price vs. features I settled on this hitch. The box it was shipped in was pretty beat up when it got to my house but I kinda expected that. The hitch survived the journey without a scratch. Its built very heavy, but not so heavy that I cant remove it my truck by myself. The fitment between all the components seems good without a lot of slop. After setting the height I hitched up to the camper and took her for a test run. I am very happy with the results so far. The only place that I get any movement is where the hitch connects to the rails but I plan on purchasing the felt pads to eliminate that in the future. The indicators on the release bar are very nice, its nice to have a visual indication and know the jaws are locked. Even after a year of use i still can't find anything to really complain about. If anyone is looking for a solid hitch that won't break the bank I would strongly recommend this one. 607787

This 5th wheel hitch fits OEM hitch mount provisions perfectly on my 2017 Ram 3500. Connecting and disconnecting works well. This hitch is heavy for one person to manage, but a hoist set-up makes for easy installation and removal. Tows well with no play between trailer pin and truck. Great product. 625666
