Installed this in my 2021 F-150 long bed. Was able to cut a hole right by my onboard outlet in the bed of my truck. Simple plug and play install. On occasion the connection isn't the best, but I think it would be better if I used some dielectric grease on the connectors.

@MitchB Thanks for checking back in, we're glad to hear that!


by:

Only feedback I have is that one of the frame brackets where we had to press fit the bolt grommet was oversized and didn't retain the grommet. We worked around it to hold it in place until we could engage the bolt. Other than that we love the fit and finish and are very pleased.

Wiring harness has worked great no complaints. Easy to install, no issues.



by:

Work like a charm, easy to install instructions for great. Would definitely purchase again.



by:

Great product. Plug and play mostly. I would be willing to spend a few more bucks if they sold it with the hole saw bit and the grease as a package deal. The plug is very easy to install. It helps to lowered the spare tire down to make room to make the connection, then all you have to do is cut a hole in the inside of the box, route the cord and mouth the outlet.

etrailer does it again. One of my items was backordered and then it appeared to be further delayed. I called, spoke with Carol and told her that I needed the parts for the upcoming 3-day weekend. She told me that she would check with the warehouse and make sure they shipped that day. I received the parts unbelievably quickly and am installing them over the next few nights. I'll update the post to comment on the install and my impressions of the product but for now I'm completely blown away by etrailer's consistently outstanding customer service. Thanks Carol, thanks etrailer.

Easy install, the etrailer videos were extremely helpful. Really the only thing I used the included instructions for was to get drill bit size information. Thanks etrailer for the fast shipping.

Ford F-250 Super Duty

I ordered the Curt Spider Gooseneck Hitch and the Wire Harness for my 2020 f250. WOW is all I can say!!! It was delivered to my door less than 20 hours. The hitch is of great quality and I can not wait to put it to work. I will continue to do business with eTrailer.



by:

The quality of materials and the fact that this plugin has a 7ft cord makes it perfect for a short bed pickup,if you take a little time in the routing of the cable it looks factory



by:

Etrailer was great to work with and Curt products are always quality and fair priced



by:
2018 Ford F-150

Fit and finish are excellent and work as expected. I would be cautious with measuring for the hole in the bed, depending on what if any bedliner is installed. In my 2018 F150 the factory spray in bedliner was thinner than the measurement in the instructions. This resulted in the hole being off center by 1/8". This is not a deal breaker, just something to be aware of, and is the responsibility of the installer. I Regularly pull a 9800 pound fifth wheel camper and gooseneck dump box with no issues.



by:

Very simple install and seems to be great quality,



by:
2019 Ford F-250 Super Duty

Easy to install with very informative i nstructions



by:

First, what I like. This system was easy to install. The cable length was perfect. The connector system to splice into the stock connectors was perfect. The directions accurately detailed the hole-saw size needed to drill in the truck bed. The umbilical from my 5th wheel seats securely. The problem I have is the mounting screws. The screws are steel while the 2020 F250 bed is aluminum, meaning there is the possibility of corrosion with dissimilar metals. The connectors design solution is rubber grommets to isolate the steel from aluminum. With only a few plug/unplug cycles, the grommets failed, the connector came loose. I had to remove the mounting system and replace with steel bolts, using silicone caulk to provide corrosion protection. Bottom line, connector mounting system doesnโ€™t work.

Perfect ready to use,easy to install,thanks



by:
2018 Ford F-250 Super Duty

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.

2019 Ford F-250 Super Duty

Always fast shipping and your customer service team is awesome! Thank you!

Very simple install, good quality.

  • Parts Needed To Install a 5th Wheel Rail Kit on a 2019 Ford F-250
    In order to install an above bed rail kit on your 2019 Ford F-250 (short or long bed), I recommend using the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit # DM8552031-71. This is also a custom fit so no drilling into the frame is required. The only other thing you may need is an in-bed wiring harness, the Curt 5th Wheel/Gooseneck Custom Wiring Harness part # C57008.

  • Underbed Base Rails and 5th Wheel Hitch for 2019 Ford F-350 Super Duty Short Bed
    While you cannot add the puck system as an aftermarket option to your 2019 Ford F-350 Super Duty, you can add an underbed rail system so you have a clean bed in your truck. I'm not sure what bolts you are referring to, but you would know if your truck came with the factory 5th wheel prep package. For underbed rails and a sliding 5th wheel hitch for your 2019 Ford F-350 you have a pair of options. - Underbed Rail and Installation Kit for Demco Hijacker # DM8551009 with the Demco Hijacker...

  • Correct Reese Custom 5th Wheel Install Kit for a 2020 Ford F-150
    The correct Reese Quick-Install Custom Installation Kit with Base Rails for a 2020 Ford F-150 (All Models) is part # RP50087-58. This will work wonderfully with the Reese 5th Wheel Hitch part 30032OE which is pretty much the same as the Reese 5th Wheel Trailer Hitch part # RP30047. It features no-drill installation into the frame so installation will be much easier than others. In order to complete your towing setup, you'll want an in bed wiring harness like the Curt 5th Wheel/Gooseneck...

  • Which Reese Under-Bed Puck Kit for 2021 Ford F-350 Long Bed
    Both the # RP87FR and the # RP39FR Reese Elite are identical parts, we sell one as a 5th wheel hitch mounting/installation kit and the other as a gooseneck hitch. Other than the part number, there's no difference between the two. Because Reese developed the factory puck system for Ford, the Reese # RP87FR and # RP39FR have the same exact puck layout as the Fort OEM puck system, so the B&W Companion for the Ford OEM pucks you'd looked at, part # BWRVK3300 would be compatible with either....

  • Which Gooseneck Hitch For a 2017 Ford F-350 Without the Factory Prep Package
    The OEM "prep" package just refers to already having 4 puck style mounting points and a gooseneck hitch already installed in your truck, so if you don't already have one then you will want to select the choice for a 2017 Ford F-350 without the OEM Prep package. The best available gooseneck hitch for your 2017 Ford F-350 with the single rear wheel is the B&W # BWGNRK1116, which is renowned for their durability and quality. This hitch will install without any drilling required since it...

  • Recommended Trailer Connector for 2020 Ford F-350 Cab and Chassis
    I don't have much information on Cab and Chassis models but so long as they have the standard US Car Connector then you can use something like the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket part # HM40975 for use at the bumper or the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector for Aluminum Beds - 7' Long # C57008 if you need to install it somewhere else.

The # C57008 does not install to the connectors you sent in a picture of though. These plug inline with the 7-way connectors at the rear of your truck.

  • Which Curt 5th Wheel Bracket Kit Fits A 2021 Ford F-250 Super Duty?
    I have another option for you, but the Curt 5th Wheel Bracket Kit # C16424 you were looking at only works with select Ford F-250/350/450s from 2011-2016. For your 2021 Ford F-250 Super Duty you will need the Curt # C16204 instead which comes with new above bed rails, as just the mounting brackets are not available. This will allow you to use a 5th wheel hitch that utilizes industry standard rails (ISR). Lastly since your truck does not have the OEM Towing Prep Package you may also be...

  • Recommended 5th Wheel Hitch Connection for Reese Elite Slider Hitch on 2019 Ford F-250 Short Bed
    The Reese Elite 18K hitch # RP30144 you have is only compatible with elite puck systems. You can add the elite pucks to your 2019 F-250 using # RP87FR. There is not an adapter for that hitch to standard above bed base rails, so installing the puck system above is the only option for that hitch. That is an excellent system and my recommendation over adding base rails and using a different hitch. You may also consider adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole...

  • B&W 5th Wheel Hitch Recommendation
    For your 2017 Ford F-250 4WD long-bed pickup without the factory tow prep package the B&W hitch option is the under-bed-mount Companion hitch # BWRVK3500-5W and the installation rail kit # BWGNRK1116-5W which doubles as a gooseneck hitch. For towing flexibility this setup is pretty tough to beat and the build quality of B&W hitches is well-known. B&W fabricates these hitches entirely in their Kansas factory and the Companion includes features like extra-thick 1-inch jaws for a tight grip...

  • 2018 Ford F-350 Super Duty Gooseneck Hitch and Wiring Recommendation
    I recommend using the Reese Under-Bed Gooseneck Trailer Hitch # RP39FR for your 2018 Ford F-350 Super Duty because this is the aftermarket version of the OEM Ford puck system so you get a clean-looking system that can be used both for gooseneck and 5th wheel towing. I also recommend picking up the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C57008 so you can make your 7-Way wiring connection inside your truck bed instead of trying to stretch it down to your bumper.

  • 5th Wheel Hitch Recommendation for 2020 Ford F250 With Factory Tow/Prep Package
    You cannot go wrong with the B&W Companion 5th wheel hitch for the Ford Tow/Prep package, just check out the product reviews! The hitch uses beefy 1 inch thick jaws that hold the 5th wheel's king pin super tightly for great ride quality. 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. If you have a short bed truck, use the sliding version, part # BWRVK3370. For a long bed truck, use the stationary hitch,...

    If you believe there's a possibility that in the future you might wish to upgrade to a larger 5th wheel and a vehicle with a greater towing capacity, then going with a higher rated 5th wheel hitch would be a good idea. The Curt A-Series 5th wheel hitches are one of my most often recommended 5th wheel hitches because they offer some nice features for the price.

  • Will Demco Hijacker Fifth Wheel Hitch Fit 2017 Ford F-250 Super Duty With 6-3/4 Foot Bed?
    Yes, the Demco Hijacker UMS Double Pivot # DM8550033 will fit in the factory puck system of your 2017 Ford F-250 Super Duty despite the fact you have a 6-3/4' bed and not an 8' bed. This is not in our fit guide for a short bed because normally a sliding fifth wheel hitch is required in a truck with a bed that is under 8'. With your Lippert Turning Point pin box you will not need a sliding hitch so the Hijacker # DM8550033 is going to be a great option. I also recommend Wiring Harness #...

    The Curt OEM 5th-Wheel Hitch Legs for Ford Super Duty Towing Prep Package - 24,000 lbs # C16017 will work with the Q25 hitch head, but it will limit your capacity to 24,000 lbs. You may also want to consider the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector for Aluminum Beds - 7' Long # C57008. This will connect to your factory wiring and give you a second 7-way wiring connection in the bed of your truck for easy connection access.

The gooseneck hitch also serves as the installation kit for the Companion 5th wheel hitch so you get both types of hitch in one setup.

    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.

    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...

    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,...

  • Can 2017 Ford F-250 Short Bed 6.7L Diesel w/ 3.55 Axle Ratio Tow 14,000 lb 5th Wheel Trailer
    Since your dealer said your 2017 Ford F-250 short bed with a 6.7L diesel and 3.55 axle ratio can tow 16,500 lbs, you can tow a 5th wheel trailer that weighs a total of about 14,000 lbs without issue. You mentioned pin weight, and for a 5th wheel trailer that will be roughly 15 - 20 percent of your loaded trailer, or somewhere between 2,100 lbs and 2,800 lbs, so you'll want to check that against the GAWR, or axle rating, on the label on your door jamb, but it should be well above that...
