This harness is exactly what I needed for our new 5th wheel to get a plug close to the pin box but not lose the plug in the bumper. The quality is good and the install is simple. The only, very small, negative is the wire ties that are supplied with it are terrible, they all broke very easily. No problem, who doesn't have a supply of them already...

This was a C57008 for a '18 F250 6' box. The item was delayed because of the new vehicle. But etrailer kept me well informed of the progress. The plug system was so convenient without having to splice the right wires and the 7' length was just long enough to locate the socket just ahead of the wheel well for my slide in camper. It also included a nifty isolation kit to avoid screwing directly to the aluminum bed.

  • What Is Needed to Tow 5th Wheel Trailer With 2020 Ford F-150 With 5-1/2 Foot Bed
    You can tow a 5th wheel with your 2020 Ford F-150 with a 5-1/2 foot bed, but you will need a standard/fixed 5th wheel hitch and a Sidewinder rotating pin box. The reason for that is the Sidewinder will move the pivot point back to the turret, which allows for the needed clearance so your 5th wheel trailer does not crash into your F-150's cab. The correct Sidewinder will depend on your 5th wheel trailer's pin box model number, as you'll need that in order to know the correct fit. For...

    There is a sliding 5th wheel hitch that will work for your 2018 Ford F-150, as well as base rails and an installation kit if you also need those for your truck. The hitch and rails for your F-150 are the following: - B&W Patriot 5th Wheel Trailer Hitch with Slider - 18,000 lbs # BWRVK3270 - B&W Custom Installation Kit with Base Rails for 5th Wheel Trailer Hitches # BWRVK2403 You made a really smart choice going with B&W as they are considered by many to be the preeminent manufacturer...

    The Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 referenced in your question will plug into the factory US connector on your 2017 Ford F-250 and the extended 7-Way will work perfectly. The issue with regards to fit on your 2017 model, as you alluded to, is the truck's aluminum body which requires some additional mounting hardware. The needed hardware is included with the Curt # C57008 Harness which is why it is the recommended option. What you can do to use the more economical...

  • Installing Curt Wiring Harness In 2018 Ford F-150 With Aluminum Bed
    I have a solution which is going to allow you to use your Curt # C56070 harness with your 2018 Ford F-150, though you will not want to use aluminum screws. Instead, you will just need the Curt Isolation Hardware Kit for 7-Way RV Plugs in Aluminum Truck Beds # C57007, which will give you just the 4 stainless steel bolts and 4 rubber well nuts that come with harness # C57008, but will not require you to purchase the entire harness.

  • What Size Pilot Hole do I Need to Drill to Install the Curt In Bed Custom Wiring Harness
    When installing the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector part # C57008 you will drill a 7/64" hole at all four of the mounting holes. This is what is stated in the instructions and will be the best practice to follow. When we do them here at etrailer sometimes we do not drill the pilot holes and it works for us but keep in mind I personally have done at least 80 of them so we are pretty practiced at it.

  • 5th Wheel Hitch & Air Bags For 2020 Ford F-150
    We can get your 2020 Ford F-150 set up to tow a 5th wheel trailer, though in regards to capacities, that depends on many different factors, including axle ratio and wheelbase so I recommend taking a look in your owner's manual for the specifics.

    It is certainly possible for the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY56FR to work on your 2020 Ford F-250 Super Duty short bed, but there are likely going to be clearance issues as these are meant for long bed trucks.

  • Towing Capacity and Recommended Upgrades for 2017 Ford F-250 to Pull 5th Wheel Trailer
    The first thing I recommend doing is simply making sure that your 2017 Ford F-250 has the towing capacity needed to pull the Grand Design Solitude 373FB Trailer. There are a variety of aftermarket components that will allow the truck to operate better and easier within its towing limits, but nothing that can actually increase the towing capacity set by the Ford. Based on my research the Grand Design Solitude 373FB has a GVWR of 16,800 pounds. This is the most it can weigh when fully...

  • Is Demco Hijacker 5th Wheel Hitch Compatible With Reese Underbed Rails on 2019 Ford F-250 FX4 4WD
    I'm glad you asked because the Demco Hijacker will work with the Reese base rails for your 2019 Ford F-250 Super Duty, but you will need a different part number. The reason is, the Reese underbed rails for your truck essentially give you the Ford puck mounting system, so what you will need is the Hijacker that fits the Ford factory 5th wheel prep. So, the correct parts that will fit are the following: - Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches...

Instead, for brackets and base rails that fit your truck and do not require drilling I recommend the B&W Custom Installation Kit with Base Rails for 5th Wheel Trailer Hitches # BWRVK2402.

  • Adding 2nd 7-Way to 2019 Ford F-250 to Provide 12V Charging Power for Trolling Motor
    The 7-way wiring harness setup in your F-250 that will connect to the camper (or to a trailer with a 7-way hookup) does include a 12V auxiliary power circuit that can maintain the deep-cycle batteries that come with the camper. This 12V power circuit is carried on the contact at the 1:00 position, as shown in the included photo.

    Yes! The Reese Under-Bed Rail and Installation Kit # RP87FR will fit with your Pullrite adapter. What the Reese rails do is essentially give you the Ford puck mounting system. If you used your adapter with the OEM puck system on your old truck, it will be the same experience with the Reese system on your new one. If you don't already have one, you'll need a wiring harness like the Curt 5th Wheel/Gooseneck Custom Wiring Harness with 7-Pole Connector for Aluminum Beds # C57008.

These rails are a custom fit for your 2019 Ford F-250, so they will install without drilling and allow you to mount a 5th wheel hitch in your truck bed using the above bed rails.

When you hook up to your fifth wheel trailer the king pin on your trailer slides into the jaws on your hitch and there is a locking pin that locks that king pin into the hitch.
