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.

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.

2020 Ford F-250 Super Duty

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.



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:
2018 FordF-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:

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



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 doesn’t work.

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.



by:

Very simple install, good quality.



by:

Excellent service! Called in my order and received my order in just a couple of days. The Curt 7 pole connector for al beds was easy to install and works perfectly for my 5th wheel. Highly recommend etrailer!!!

  • Can Curt Rails Install In 2018 Ford F-150 With Bed Liner
    Hi Francis; the Curt Custom Fifth Wheel Installation Kit # C57008 can be installed with a bed liner. However, the installation process depends on the type of bed liner. If it is plastic it must be trimmed for metal to metal contact. If it is a spray-on liner then no modification is required. With the bed rails installed you will be able to use the # C16541.

  • Recommended In-Bed 7-Way for a 2020 Ford F-350
    I would be happy to help you. I recommend the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 10' Long item # C57008 for your 2020 Ford F-350. This is designed for aluminum beds like your model truck has. 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 trailer easier and more convenient.

  • Do I Need a Sliding 5th Wheel Hitch for a 2019 Ford F-250 Short Bed?
    Congrats on the new trailer! You will need a sliding 5th wheel hitch. A standard fixed hitch like the Curt A20 item # C16140 won't provide you with the necessary clearance you'll need. You'll end up running the nose on your Dutchman into the back of your F-250's cab. Since you already have a set of Reese 5th wheel rails installed, the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider item # C16541 will be a great addition to your set up. The Curt A20 has a 20,000 lbs capacity and will give...

  • Recommended Gooseneck Hitch for a 2017 Ford F-250 w/ Inner Brackets Welded to the Frame
    Yes, we do. What you are describing sounds like the Inner Frame Brackets for Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Hitch item # RP27FR. I have attached a picture below. These come welded to the frame exactly where you described. With these already on your 2017 F-250, I highly recommend installing the Reese Under-Bed Gooseneck Trailer Hitch item # RP39FR. This will not only give you a gooseneck hitch but also the factory puck system that Ford installs as...

  • 5th Wheel Rails Needed to Use a Curt Sliding Hitch on a 2019 Ford F-250 Short Bed
    The exact part that you need to use your Curt sliding 5th wheel hitch, like part # C16541, in the short bed of your 2019 Ford F-250 depends on if you have the OEM prep package or not. If you do have the OEM prep package then you simply need the Elite Series Underbed Rail Adapter # RP30156 which drops into your puck system. If you don't have the OEM prep package you need a base rail kit like part # RP50074-58 which doesn't require drilling for the install. Both of these options give you...

  • Does B&W Custom Installation Kit With Base Rails For 2018 Ford F-150 Have Anti-Corrosion Protection
    Excellent question, and there is anti-corrosion protection for the aluminum bed of your 2018 Ford F-150 that comes with the B&W base rails and install kit that fits your truck, though it is not in the form of shims.

  • What All Drilling is Required to Install B&W Turnoverball Gooseneck Hitch BW77FR on 2023 Ford F-150?
    The only drilling you will need to perform on your 2023 Ford F-150 to install the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BW77FR is the 4" hole for the ball and the four 1/2" holes for the safety chain hooks. You will not need to drill into your frame to attach the side plates. I recommend installing the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C57008 when you install the gooseneck hitch. This will allow you to plug in the connector inside your bed rather than running...

  • Parts Needed To Use Curt A16 5th Wheel Hitch In 2019 Ford F-250 XLT without Factory Puck System
    If the 2019 Ford F-250 XLT does not have the OEM Pucks, then they can still use their old Curt A16 5th wheel hitch as long as it is for ISR (Industry Standard Rails), they'll just need to install rails in the bed. If they don't have and ISR hitch they can replace the legs with # C16920 to convert it to ISR. I'd go with the Curt Installation Rails # C79BR. These are custom fit for the truck so install will be pretty quick compared to the cheapy universal kits, and will work perfectly with...
