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. 303440

Bought this harness for our new Ram 3500. The local RV repair place wanted $250.00 to splice into my truck's harness, but I elected to get this custom harness. Gave me an excuse to buy a hole saw, and after watching the video, I was able to successfully install the harness in a little less than an hour. The connections are solid, the cable was easy to route, and the end result is cosmetically and functionally excellent. The harness was long enough to be able to choose among several routing paths. I was happy that they included dielectric grease, and was also happy that I had a stash of self-tapping screws in my parts box, because one wasn't included in the product package. You need a self-tapping screw to attach the ground to the truck frame. This could result in a trip to the hardware store if you don't happen to have some sitting around. The other item you will need is some longer zip ties. The ones included in the package are small, suitable for tying to a small hose, another wiring bundle, or an existing frame mounting point, but having longer ties will make the job easier, especially if you need to get creative with routing. As always, great service from etrailer.com. It is a real pleasure to deal with these folks. 202738

I bought this harness a couple of months ago, but being winter, I am just now getting outside to install it. The item appears to work exactly as described. The instructions could be more detailed. For instance there is a white wire with a screw connection hole which was not mentioned at all in the instructions. I assumed it to be a ground wire and grounded it to the frame of my truck. But the 90 degree aspect of the harness is great. It let me put it in a tighter spot. It probably took me a total of less than an hour to install it. What instructions there were, were accurate and made it simple. I plugged our 5th wheel into the new outlet and all was good. Then plugged the 5th wheel into the outlet at the back of the truck where the original connection was. Also good. So I have an in bed connection for the 5th wheel and a below the tailgate connection for a bumper pull. Could not be happier. Well, actually, I am happier about something than the item. I am extremely happy about my dealings with Etrailer. It shipped almost instantly and arrived sooner than I could have imagined. As it turns out, I was not in a hurry (obviously), but I could have been. And if I had been, it would have been awesome to have gotten my item that quickly. Thanks guys/gals. 172847

I installed this plug and it was extremely easy and a very clean install. I wanted to use this unit because it did not require any splicing which can cause issues with the ITBC. It was only one 2-1/8 hole to drill and 4 self tapping screws and it was installed. I am very happy with this piece and would recommend it to anyone needing an in bed plug. 216893

How good is free shipping, our Order was placed about 8pm est on Thursday Jan 19th, and arrived Jan 25th before I returned from work at 4pm. Just sold the F-150 I installed the previous B&W fifth wheel hide a ball hitch in. Love this hitch set up, after arriving at a campground and unhooking the camper I have FULL use of the truck bed. Install of round two begins in the morning, directions are simple and easy to understand. George J from E-trailer has been keeping me updated with information about my delivery status and made himself available had I had any questions. Wife and I have been camping for about four years, on our second RV and now our third truck and have been totally satisfied ordering everything we needed from E-trailer over that time, (about 18-20 orders to date) adding to the great products E-trailer provides is the HOW TO DIY videos on many products. 338589

Our truck is a 2015 Chevy Silverado 2500 HD and we our going to be traveling 24/7 and now no worries about new paint being damaged by cable rubbing on tailgate while driving. 136700

This wire harness was exactly what I was looking for. My GMC Sierra only had a bumper connection and this meant the cable from my 5th wheel RV hung over the tailgate and wasn't well contained. After watching the installation videos, the installation was straight forward. While waiting for the wiring harness to arrive, I purchased a hole saw and cut the hole in the side of the truck bed. Once the harness arrived, installation took about 30 minutes. It is now much handier to have the cable to the 5th wheel in the truck bed when connected. 232065



- 41157

by: Aaron05/26/2016


Great product. Installation time was ten to fifteen minutes even with cutting the hole in the box. This is an excellent kit overall. The zip ties that came with it were a little small, so I used my own. It would be nice if the kit came with the ground screw. I would recommend this product to anyone. I installed it on my 2004 Chevy 2500 HD. 252037

Great product easy install plug n play. Installed on 2011 Chev 2500 hd to pull 5th wheel trailer plugged over tailgate when first bought but got extremely tight on turns and almost unplugged from truck installed in bed of truck no worries now would highly recommend. Great price also 20.00 dollars cheaper than RV store 133750

by: Trever H05/13/2014


I assumed this would be a plug and play connector and go together seamlessly. However I found that the end connector that plugs into the factory harness does not lock appropriately. I made sure there were no bent pins. The locking clip and connector did not want to stay locked and I do not understand why. A 1/2 hour install turned into 2.5 hours which ended with ultimately using a zip tie to hold the two connectors together. I'll probably end up buying a another harness that will work. 130421

[another website] sent me twice, a 7 way plug and 3ft of wire for this part . I was running out of time and knew if I ordered this from e-trailer they would get it right! They got it right!! Shipping was fast as well as packaging. Thanks George!! This Pooduct was easy to install and works great! I like that the lid flips up 180 degrees. It also comes with the die-electric grease!! I used spray bedliner material around the hole to prevent rust! 432218

I had to replace the 7 pole plug. After a few months the plug started getting hot. Checked all the connections, all of the wires were secured. Went to local parts store and got a replacement. Same brand so far working very well. Not sure if I would buy online again. Because if I have a problem I can not wait for another plug to be shipped. So I am stuck not being able to use my trailer. I think Hopkins make good products. I just got a bad one. 323357

This was really easy for not too mechanically inclined person. It really is a simple plug and play device. Just read the instructions or watch the installation video on e-trailer website. Visually verify that you are only drilling through a single panel if possible. Sometimes there is other sheet metal in there. Also have a quality metal hole saw on hand. Makes a lot smoother cut. All functions worked perfectly after installation. 310592

Product arrived quickly and in perfect condition. The harness took about 30 minutes to install from start to finish. Good quality and you really don't need the instructions because this is a plug and play part. I had to drill one hole with 2 1/8" hole saw to mount the plug receptacle using the supplied four self drilling screws to secure it then plug it in using the adapter and your done- Easy. 105287

This is a great brake harness for my new Dodge Ram 2500 truck making it easier to hook up the 5th. wheel trailer brake conector. All I can say is Shipping was excellent, quality is excellent, instructions were very easy to follow as well as a u-tube video. And last the price was awesome compared to others. I have to give ETRAILER a full thumbs up on this harnesse. 394381

I had a spray-in done on my truck, and was going to pay to have this installed at the same time. After watching the video on etrailer.com I decided to do it myself. What a waste of money that would have been! Total time was just under 10 mins, and was EXTREMELY simple. YOU GOT THIS. 121918

Received the Hopkins wiring harness yesterday and installed it this afternoon. Any one could install this harness it is that easy. It took me longer to find my 2 1/8 inch hole saw than it took to install the harness. Just unplug factory harness and plug in new one and was done. As usual I received great service from etrailer. 140662

Plug and wiring were easy to install,just followed directions, entire project took less than one hour including tying up the wires and drilling the hole. Plugged trailer connector into both plugs and they worked just like they should. Probably one of the best and most reasonably priced kits on the market, I highly recommend! 297270

Very well satisfied with product, easy to install after watching video. Only down fall was the shipping, UPS delivered it to my hometown post office, instead of my house. Had to make a trip to town (12 miles) to get my parts, plus delayed installing them a couple of days. Otherwise very happy to have it inside the pickup box. 125176

Well thought out design on this product. Literal plug and play, just route it and secure the excess. I chose this one over the others they carry because the socket mounted to the bedside is replaceable separately should you snap the cover off etc. The cover opens 180 degrees too for a bit of extra visual when plugging in. 334467

I was a little skeptical when I ordered because I've ordered stuff on the internet before only to have it show up weeks later or even a call telling me a mistake was made and they didn't have the product but I have to say with etrailer I got my product fast and at a great price. I will definitely order from them again! 104935

This was the easiest trailer wiring I have ever done..Even though it was so simple to install, the finished job looks like a professional did it.. The people at E-Trailers went out of their way to make sure I received the wiring harness, even after it was on back order.. OUTSTANDING service and product.. THANK YOU. 82035

Good product - would recommend it. Need to take care picking where you place it - there are support beams under the bed that limit its location. Tried to squeeze it between the beam and the wheel well - clipped the edge of the inner liner but it worked. Also had issues with getting the trailer plug in - very tight. 136499

Problems from the start and and has not improved. Install was simple. Problems with trailer plugging into the outlet. More than one trailer with same result each time. Other trucks we have do not have any problems with the same trailers. To connect, usually have to force in with and will loose connection as we pull. 400459

I stumbled across this part while looking at another part to try and fix what this one does. I received it a few days after ordering and installed it yesterday. I had the chance to see it in operation this morning and it works better than I imagined. Easy to install. The video on the website was very helpful. 207762

I would rate so far as good to excellent. I installed today and the instructions were easy to follow and accurate. Will be leaving on an extended trip with the truck next week. My only concern is that the spring seems weak and I am concerned that the plug may have a tendency to come out during travel. 371010

E-trailer experience - awesome customer service. Quick responses on questions. This product, I literally installed this in my truck in 20 minutes.

Product is of excellent quality. I liked most the ease of installation. Product was received as advertised and in a short period of time. The video provided on the web site was very helpful in detailing installation. It provides me with the wiring plug for fifth wheel trailer in a very convenient place. 181669

This kit is just what the Dr ordered for my Chevrolet 2500 HD! I installed this kit to make it easier to tow my gooseneck and 5th wheel trailers. Plugging in the light cord in the bed keeps it away from hanging it up and pulling out of the bumper mounted socket. Installation was a breeze!! Thank you!! 163606

  • What is the Best Truck for Towing a 5th Wheel Trailer
  • You are doing the right thing by doing the research first. There is a lot of conflicting information out there so let me break it down for you and I will provide some part recommendations at the end. Basically, if you want to tow a 5th wheel trailer, the best trucks are going to be long bed 3/4 or 1 tons like a Ford F-250/F-350, Chevy/GMC 2500/3500, or Ram 2500/3500. Half ton trucks could work but are not nearly as capable as the larger trucks. A long bed for sure is something you will...

  • Unlike the 3/4 and 1-ton Ram trucks the 1500 does not have a separate towing capacity for 5th wheel or gooseneck towing. Based on your truck, 2016 Ram 1500 Quad Cab 4x4 with 6 foot, 4 inch bed, 5.7 liter motor, and 3.21 rear end, and with standard rather than premium options the capacity can vary depending on the trim level of the truck: Outdoorsman, Big Horn, and Lone Star, 8,250 pounds Tradesman and Express, 8,150 pounds Sport, 8,000 pounds Laramie, 7,950 pounds Payload in general...

  • 5th Wheel Trailer Hitch for 2016 Chevrolet Silverado 3500 with OEM Factory 5th Wheel Prep Package
  • We have exactly what you want. For the 2016 Chevrolet Silverado 3500, I recommend the Curt Q24 5th Wheel Hitch, # C16545-16025 because it was specifically designed to drop right into the under-bed mounts that come on your truck and it has a towing capacity of up to 24K. One thing to keep in mind is that this hitch is not compatible with Sidewinder or Reese Revolution pin boxes because the wedge on the bottom of those pin boxes can damage the Q series head. If you have a Sidewinder or Reese...

  • 5th Wheel Trailer Hitch and Installation Kit for a 2017 Ford F-250 Short Bed
  • For your new 2017 Ford F-250 short bed you have some options for 5th wheel hitches and installation kits. For an install kit I recommend going with a custom kit, # RP50074-58. With a custom kit there is less drilling required and it takes less time to install compared to universal kits. And for a hitch I recommend the Reese Titan 20 # RP30870. This hitch is rated for 20,000 pounds, features the super-secure serrated dual jaw design, and it is cushioned. I have linked a video review of...

  • Recommended No-Drill Fifth Wheel Frame Bracket/Bed Rail Install Kit for 2015 Chevy Silverado 2500
  • Reese offers two different no-drill frame bracket/bed rail options for your 2015 Silverado 2500, neither of which would require drilling into the truck frame. The inboard bracket kit, part # RP50066-58 is a bit less expensive, but is a bit more difficult to use, as the attachments between the bracket and the bed rail are made on top of the frame members, making them a bit more difficult to get to. Another option would be the Reese outboard rail kit, part # RP56001-53 that used bed rails...

  • Best Wiring Options for Towing a 5th Wheel Trailer
  • You have a few options when it comes to 5th wheel wiring for your truck. Most trucks come with factory 7-way trailer connectors at the bumper. If your truck has a factory 7-way, then I recommend installing a 5th wheel wiring harness like the Hopkins Endurance 5th Wheel Harness, # 41157. In-bed harnesses provide a quick and easy connection point in the bed, so you don't have to modify the existing trailer harness to make it longer or use an extension. This harness has a 90-degree plug,...

  • Fifth Wheel Hitch Recommendation for a 2011 Chevy Silverado with 5-1/2 ft Bed
  • It is possible to install a fifth wheel hitch in the bed of a 5-1/2 ft bed 2011 Chevy Silverado 1500, but since the bed is so short it makes things a bit more interesting. The only slider hitch we offer that will slide far enough back to give you turning clearance is the Demco Hijacker Auto-Slide part # DM8550040. This hitch has 22-1/2 inches of sliding travel compared to most sliders that can only go about half that. For a rail kit to install this hitch you will need the custom install...

  • Brake Controller and Wiring Harness for a 2016 Ford F-150
  • If your new Ford F-150 came with the factory installed brake controller then you would not have to add an aftermarket one to activate the trailer brakes. If the truck does not have the factory controller and you need to control the brakes then you will need one. For a brake controller I recommend the P2, # 90885, because its easy to set up and use and it is reliable. You will also need the appropriate wiring harness to plug the controller into the truck.

  • Recommended System To Tow A Gooseneck Or Fifth Wheel Trailer With 2016 Chevrolet Silverado 3500
  • I do have a system that lets you tow either a gooseneck trailer or a fifth wheel. First, you will need the EZr Double Lock Underbed Gooseneck Trailer Hitch, part # C611-624. This system gives you a gooseneck hitch in the bed of your truck with a 30,000-lb capacity. You would then need an adapter, part # C16220 to install in the gooseneck ball opening in the bed of the truck. This gives you base rails for a fifth wheel hitch like part # C16245.

This plug-in harness provides on one end dual round U.S. Car connectors in a Y-arrangement that allow you to tap into your existing 7-Way (while keeping all of its functions active for your tow rig).

  • Recommended Fifth Wheel Hitch for FW Flagstaff # 85258IKWS Compatible with Reese Revolution Pin Bux
  • The Reese Revolution is the OEM version of their aftermarket Sidewinder. Lets begin with the Curt Q20 fifth wheel hitch, part # C16130. Curt makes a great hitch, and I really like the spherical axial bearing they use to allow full 360 degree tilting movement. The double jaw used in the hitch grabs the fifth wheel king pin from all sides, reducing rattle and chucking. The built-in cushioning further reduces how the rattling, clatter and chucking is transferred to the vehicle. However,...

We have a video that shows the installation process. Because you have a short bed pickup, please make sure your hitch has a slider on it.

First, you can use # 41157. This connector plugs in line with the factory 7-Way just behind the connector at the back of the truck. Second you can use # PK11893-11932. This harness also plugs in line with the factory connector but requires a little manual hardwiring as well. The diagram for this is on the...

It's the exact same sliding fifth wheel hitch that's designed to fit into a B&W Turnover Ball Gooseneck Hitch. We do this so it will run through our fitguide. If you don't already have a 7-way trailer connector installed in the bed of your Ford, you can easily install one using part # 41157.

But the vehicle manufacturer has already done all of that work for you! The towing capacity is in the owner's manual. You can also look at the sticker in the door jamb. If you subtract the gross vehicle weight rating (GVWR) from the gross combined weight rating (GCWR) then that will tell you the towing capacity of the truck. But I can tell you now that a 2016...

  • 5th Wheel Towing Capacity and Hitch Recommendations for a 2016 GMC Sierra 2500HD Short Bed
  • The dry hitch weight, also called tongue weight for travel trailers or pin weight for 5th wheel trailers, is the amount of weight pushing down on the trailer hitch. Dry means the trailer is empty; no cargo, water, propane, just the trailer by itself. So the dry weight is less important than the actual hitch/tongue/pin weight when the trailer is loaded and ready to tow. Based on the figures you have provided the trailer has a hitch weight that is 21 percent of the gross trailer weight...

I like the Draw-Tite Hide-A-Goose, # 9464-46. But the general applications for gooseneck hitches for the 2013 Dodge Ram 1500 exclude models with the Crew Cab. The hitches come with the proper installation kit. You may also be interested in added in-bed wiring using # 41157. On a short bed truck, you can run into clearance issues...

The Curt Double Lock, Flip and Store Underbed Gooseneck Hitch # C60723 has been confirmed as a fit for your truck and would work well for you. For a 7-way to install in the bed of your truck to make connecting your trailer lights easier you would want the part # 41157.

  • No, you do not have to remove the bed on your 2015 Ford F-250 to install Curt gooseneck trailer hitch # C60720. The only variation of the installation is that on 2011 and newer model trucks the hitch head needs to be rotated when installed so that ball cylinder faces the rear of bed to line up with factory punch-out in truck bed. This will place pull rods on passenger side of vehicle. I have included a link to the installation instructions for you. To add a 7-Way trailer connector in...

The wedge isn't compatible with the Q20 or Q24 fifth wheel hitches, so it's not recommended to use either of those in conjunction with the Revolution/Sidewinder.
