I added this to the left front of my bed for a slide in truck camper. It connected into the factory 7 pole connector in the rear of the bed. Fits well appears to be well made and installation was easy after getting the courage to cut a 2 1/8 inch hole in my bed.

  • Which Gooseneck Hitch Fits a 2022 Ford F-250?
    The correct B&W gooseneck hitch for a 2022 Ford F-250 is the Turnoverball Underbed Gooseneck Trailer Hitch item # BWGNRK1116. This system fits both the 6-3/4' and 8' bed lengths. This hitch is custom fit and includes all hardware necessary to complete installation on your truck. It has a massive 30,000 lbs capacity. I have linked an installation video below to help you get this gooseneck hitch set up. To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck...

  • Recommended 5th Wheel Wiring Harness for 2022 F-350 Diesel
    I reached out to Curt and found that the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 has the same connectors as the # C57010 which is confirmed to fit the 2022 Ford F-350 with factory 7-way. This means that the # C56070 will also fit if you have a factory 7-way. However, you would want to use the # C57008 instead since it comes with the rubber well nuts that separate the stainless steel bolts from your aluminum truck bed to help prevent galvanic corrosion.

  • B&W Companion or a Demco Hijacker? Which is Better for a 2021 Ford F-250?
    I would be happy to help you set your 2021 Ford F-250 up to tow your 5th wheel trailer. The Demco Hijacker Premier Series Double Pivot 5th Wheel Trailer Hitch item # DM6076P-21K you referenced is a great hitch and would definitely get the job done. As far as ease of access and using your bed goes you will need the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit item # DM8552031-71 to use this hitch. These rails do take up space inside your bed. The best option...

  • Difference Between 7-Way Connector With Flat Versus Round Connectors For 2022 Ford F-350 Super Duty
    The flat connectors you found on your 2022 Ford F-350 Super Duty is where the Curt T-Connector Vehicle Wiring Harness # C69CR connects to the factory wiring harness. This is designed as a replacement harness or for trucks that did not come with the factory 4/7-way connector. It is shorter as it is only designed to connect to the bumper. The Curt 5th Wheel/Gooseneck Custom Wiring Harness # C57010 is designed to tee in at the Bumper Connection # HM40975. This provides a 2nd 7-way connector...

  • Is There a Difference Between RP87FR and RP39FR for 2020 Ford F-350 Super Duty
    The two parts you mentioned are both the same Reese Elite Series Under-Bed Rail and Installation Kit that fit your 2020 Ford F-350 Super Duty, giving you the ability to pull a gooseneck trailer with a gooseneck ball or use a 5th wheel hitch in the puck system. The only difference is that we have one listed as a 5th wheel install kit and the other as a gooseneck hitch, but the # RP39FR and RP87FR are the exact same, the Reese Elite Series Underbed Kit.

  • Wiring Needed To Install 7-Way Connector In Front Of Bed On a 2019 Ford F-350 With Factory 7-Way
    The Curt 5th Wheel/Gooseneck Custom Wiring Harness # C57010 uses a 10' long harness. It will connect in line of your current 7-way in your bed allowing you to install another 7-way in the front of your bed on your 2019 Ford F-350. This will allow you to not have to use an Extension # C56080 with your slide in camper.

    Definitely a smart move to ensure the proper fit so you get the correct B&W Companion fifth wheel hitch for your 2019 Ford F-250 or F-350 with the Ford fifth wheel prep package. The only thing you didn't say is if you had a short or long bed so I'll give you the options for both.

  • Recommended 5th Wheel Hitch & Rear-Axle Air Bag Kit for 2017 Ford F-250 4WD with 6-3/4-Ft Bed
    For your 2017 Ford F-250 4WD with 6-3/4-foot bed you will need a slider-type 5th wheel hitch like the Pro Series # PS30121 or the Curt # 16516 along with a base rail installation kit like # RP50074-58. A slider hitch will give you the clearance you need for making sharp turns. Between the two I suggest the Curt hitch since it offers more slider travel. You can still use the Reese install kit # RP50074-58 since it costs a bit less. For a wiring harness for the truck bed you can use part...

  • How Long Does it Take to Install B&W Turnoverball Gooseneck Hitch on 2023 Ford F-250, F-350 or F-450
    This can vary greatly depending on the individual and their comfort level or experience with various tools but an estimate is somewhere in the 3 hour mark, give or take. The GRNK1123 does fit a 2023 Ford F-250, F-350, or F450 Super Duty, and our part number for that is the following: - B&W Turnoverball Underbed Gooseneck Trailer Hitch # BW73FR The only other thing I wanted to add is that if you need gooseneck wiring for your truck the correct part is the Curt 5th Wheel/Gooseneck Custom...

    The Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches item # BW83FR and item # BW73FR are identical kits that both fit the 2023 Ford F-350 with either the 6-3/4' or 8' bed lengths. It looks like item # BW83FR was the original inventory number but they both have the same components, installation method, and capacities.

  • Recommended 5th Wheel Rails for a 2022 Ford F-250
    Congrats on the new truck! I do not recommend an under bed mounting system over above bed rails. After market under bed systems have limitations on what type of hitches and pin boxes you can use and sometimes expensive adapters are required. There is nothing comparable to the Ford OEM puck system available for your 2022 Ford F-250 either.

The correct one for your 2022 F-250 is the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails item # RP56017-53. I have linked an installation video below.

This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel or gooseneck trailer easier and more convenient.

  • Truck Bed Wiring Harness For 2019 Ford F-250 Super Duty For Slide-In Camper
    To connect to the plug on your 2019 Ford F-250's truck bed camper, what you will do is use a 5th wheel/gooseneck wiring harness. The best location really depends on the camper, but most find positioning the harness towards the rear of the bed (closer to the tailgate) to be difficult because of limited clearance, so further forward in the bed would be the better option. For that you'll want a longer, 10 foot plug-in harness: - Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector...

  • What Is Included In The OEM Prep Package For A 2021 Ford F-250
    The OEM Prep Package is just a manufacturer package that gives you an in-bed 7-way, like part # C57010, and four "pucks" that allow you to drop puck-style 5th wheel hitches. I've attached a picture below of what the pucks look like to give you a better idea. The system essentially just makes things much easier since it provides a clear bed when not in use and is easy to mount into.
