Trailer hitch has worked exactly as it should. Could not ask for better performance.

Easy install. Hardest part was using the hole saw in my aluminum bed. Snapped right in to the existing connector. I also tested out the connections with a meter to insure all were working.

- 20110-010

The first harness i ordered did not fit correctly. This harness fit and functioned perfectly. This harness is a very easy install just be sure there isn’t anything behind where you will make your 2” hole. I almost put it where the frame for the bed wouldn’t have allowed it. As always, etrailer was exceptional, even with the harness I had to return! Thanks

This installation was easy and only took about a half hour to get it done.. It would have take me 15 minutes if I had known that I should notch the hole for the cord to fit through..

  • In-Bed 7-Way Trailer Connector Installation
    Based on the items you viewed it appears that you're installing a second 7-way socket in your truck bed for 5th wheel or gooseneck towing. The usual connection point for an in-bed 7-way is at the rear of the existing bumper-mounted 7-way. Since I don't know your truck information I'll give you an example for an F-150. Factory 7-way wiring has a connector that plugs in to the back of trailer connector, like the round U.S. Car wiring connector shown in the linked photo. An in-bed 5th...

  • What is Best Truck For Towing Hefty Fifth Wheel Trailer That Is Over 20,000-lbs
    First, both the Ford F-450 dually and the Dodge Ram 3500 dually are solid trucks that have the muscle to tow a hefty fifth-wheel trailer like the Jayco 4212 fifth wheel that you are looking at. As you look at your options, make sure to go with the longer bed that is 8 feet so that your towing is easier overall as well as this leads to the most cost-effective setup. It sounds like you are looking at the diesel option regarding fuel which is a great choice for hefty fifth-wheel trailers,...

    The Draw-tite Hide-A-Goose Underbed Gooseneck Trailer Hitch # 9468-94 and Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88399 will work together well and not have any interference issues on your 2019 Ford F-250 FX4. The Hide-A-Goose # 9468-94 does have the highest weight capacity of the available goosenecks for your 2019 F-250, and the air bags are a great addition to keep the back end from sagging while your towing. I do recommend that you install the gooseneck first, that...

  • Recommended B&W Companion 5th Wheel Hitch-2020 Ford F250 w/ Tow Prep Package
    The exact hitch needed can depend on the weight of your fifth wheel and the length of your truck bed. For a short bed truck, in most cases you'll need a sliding hitch like # BWRVK3370 unless the front corners of your fifth wheel are dished in to allow sharp turns without the fifth wheel corners hitting the corner of the truck cab. A long bed truck would use a stationary hitch like # BWRVK3300. The stationary hitch is also available in a 25K capacity model as # BWRVK3305. For a trailer...

    I'd be happy to give you the weight of the B&W Companion 5th Wheel Trailer Hitch with Slider # BWRVK3400-5W. I checked with the manufacturer, and the head of the Companion weighs 75 lbs and the base weighs 212 lbs for a total of 287 lbs. It's an extremely durable, high-quality hitch that is built to last. Like all sliding 5th wheel hitches, it is heavy, but if you want to take it out of your truck, there is a part made to do that, the B&W 5th Wheel Lifting Device # BWRVXA3130. You...

  • Gooseneck Hitch Recommended for 2018 Ford F-250 Short Bed
    Assuming your truck doesn't have the factory tow/prep kit with the pucks in the bed, I'd recommend the B&W Turnover Ball Gooseneck Hitch, part # BWGNRK1116 which is compatible with a short bed truck. The gooseneck ball is included, and the hitch also serves as a mounting point for the B&W Companion 5th wheel hitch, part # BWRVK3400-5W should you decide later on that you'd like to pull a 5th wheel.

    You can still use your Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550034 in your 2019 Ford F-250 with a 6-3/4' bed, and the best rail system for this hitch and truck is the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552031-71. The reason this is the best kit is because it does not require any drilling into your frame rails to install. This is not only great for your truck but also means the installation is going...

    Having the scooped corners on your fifth wheel is a neat feature that will eliminate the need for a slider and save you some dollars on the hitch purchase. The 20K capacity # BWRVK3300 B&W Companion you'd looked at would work well for you.

    You're correct. The # BWRVK3500 Companion you referred to is intended for vehicles only equipped with the B&W Turnover Ball in the truck bed, not the factory puck system. We do have an excellent solution, though. For your 2021 Ford F-250 with the factory tow/prep puck system, I'd recommend the B&W Companion, part # BWRVK3300 for the long bed or # BWRVK3370 for the short bed. After a one-time initial adjustment, the hitch will only take a minute or two to install. If you'd like the...

  • How to Position B&W Companion 5th Wheel Hitch Pivot Arms to Install on 2017 Ford F-350 Long Bed
    Since you have an 8 foot bed, either way you set up your B&W # BWRVK3305 Companion pivot arms could be attached in either orientation. I'd recommend the forward position, which will distribute a bit more weight to the front truck axle. This helps make the truck's handling more stable. If you don't already have a 7-way trailer connector installed in the bed, you can install one using # 20110-010. I've linked you to a video showing the installation of the wiring harness.

    For your 2018 Ford F-250, you are correct that with the Lippert Turning Point Pin box on your trailer you do not need a sliding 5th wheel hitch for your 6-3/4 foot bed. The best option to give you the most height adjustment is the B&W Companion OEM 5th-Wheel Hitch for Ford Super Duty Prep Package # BWRVK3300 for a 20K capacity or # BWRVK3305 for a 25K capacity. Both of these hitches offer height adjustment between 16-3/4 - 18-3/4 inches. There is only one hitch that is slightly taller...

    To mount a 5th wheel hitch like your B&W Patriot 5th Wheel Trailer Hitch with Slider # BWRVK3270 in your 2019 Ford F-350, you will need the B&W Custom Installation Kit with Base Rails for 5th Wheel Trailer Hitches # BWRVK2402. The reason is, the bolts you are referencing in the bed of your '19 F-350 are what is keeping your truck bed in place and are not actually part of the puck system, which is why the Demco 5th Wheel Rail Adapter # DM6175 won't work.

  • Is Reese RP30156 Compatible with Puck System in 2020 Ford F-350
    The Reese # RP30156 puck to rail mounted 5th wheel hitch adapter would indeed be fully compatible with the Reese # RP30051 sliding 5th wheel hitch. Both would work perfectly with the puck system in your 2020 Ford F-350, but if your truck is the long bed model, you wouldn't want to use the sliding feature, keep the hitch in the fully forward position. Operating with the hitch slid rearward can place too much weight rearward of the truck's rear axle and unspring the front suspension, which...

For a short bed I recommend the B&W 20K Slider hitch # BWRVK3400-5W and the under-bed install kit # BWGNRK1116-5W. If you have a long bed you'll use the same install kit but instead use a fixed hitch # BWRVK3500-5W. I strongly urge...

The hitch uses a cam-action latch handle that makes releasing the hitch easy, even if the terrain you're on isn't perfectly level.

  • Can Curt Gooseneck Hitch Be Used for 2-Horse Trailer on 2017 Ford F-150

So yes, the two would work together perfectly. You won't need anything else to complete the installation other than the hitch and the Reese puck system.
