Im really sorry to hear that, Renee. Im going to make sure the missing part is shipped to you. Be on the lookout for an email!

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.

  • Recommended B&W Turnover Ball System for a 2023 Ford F-350 w/out the Prep Package
    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. I have previously checked with B&W on this Turnoverball system, since you do not have the prep package you will want the B&W Turnoverball Underbed...

  • Recommended B&W Turnover Ball Hitch for a 2023 Ford F-350
    I checked with B&W and can confirm that the B&W Turnoverball Underbed Gooseneck Trailer Hitch item # BW73FR does fit the 2023 Ford F-350. It fits both the 6-3/4' and 8' bed length trucks without the OEM prep package. To make towing with a 5th wheel easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 10' Long item # C57010. 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...

    To add an in bed 7-way connector to your F-350 you will want the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C57010. I really like this harness because it 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 gooseneck or 5th wheel trailer easier and more convenient. What sets this wiring harness apart from the others is that this kit includes rubber well nuts that separate the included stainless steel bolts...

  • How to Use a B&W Companion Gooseneck-to-5th-Wheel Adapter BWRVK3500 on a 2024 Ford F-250
    There are two ways to use a B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter item # BWRVK3500 in a 2024 Ford F-250. Which option you use will depend on whether or not your 2024 F-250 has the factory puck system. I have listed both options below: With the OEM Puck System - Replacement Base for B&W Companion OEM 5th Wheel Trailer Hitch item # BWRVB3305. This will allow you to replace the base of your Companion item # BWRVK3500 and reuse the head. This will give you the B&W Companion...

  • Recommended 5th Wheel Rails for a 2022 Ford F-350
    We do have a set of rails and brackets for the 2022 Ford F-350. They are the Curt Custom Fifth Wheel Installation Kit for Ford item # C79BR. These will work with any 5th wheel hitch that is compatible with industry standard rails so you should be good to go with your Reese hitch. These rails fit both the 6-3/4' and 8' bed lengths. It will not fit the cab and chassis models. To make towing with a 5th wheel easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/...

    It's not a silly question at all, and yes, the 2-5/16" gooseneck hitch ball does come with the Curt OEM gooseneck that fits the 2023 Ford F-250 & F-350 Super Duty: - Curt Custom Underbed OEM-Style Gooseneck Trailer Hitch # C59VV If you also need gooseneck wiring for your truck the correct fit is the 5th Wheel/Gooseneck Wiring Harness # C57010.

  • 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...

    So long as your customer's Pull-Rite 24k 5th wheel hitch mounts to industry standard rails, you'll want the B&W Custom Installation Kit w/ Base Rails item # BWRVK2402.

  • 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...

  • 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. To add a custom fit set of above bed rails to your 2022 F-250, I recommend the Reese Quick-Install Custom Installation Kit w/ Base Rails item # RP50074-58....

  • What is the Difference between the RP87FR and the RP39FR for My 2021 Ford F-350 Super Duty?

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.

Both of these hitches will work with your F-250's Turnover ball system. Since you have the shorter bed length I recommend using the slider.
