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.
by: Craig11/02/2022
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.

Work like a charm, easy to install instructions for great. Would definitely purchase again.
by: Kyle 07/28/2022
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.

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.

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: Lucas09/09/2022
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.

Etrailer was great to work with and Curt products are always quality and fair priced
by: Jay01/22/2022
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.

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: William 01/26/2021
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!!!

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...

- Demco Hijacker Autoslide 5th Wheel Hitch Recommended for 2021 Ford F-150Demco offers both an 18K or a 21K Hijacker Autoslide hitch. Given that you have a 1/2 ton truck, I'd recommend the 18K unit, which is part # DM8550034. You'll also need a bracket/rail kit. The Demco kit is part # DM8552028-71 would take roughly 4-1/2 hours to install and would require drilling into the truck frame. Reese offers the # RP56034-53 which uses existing holes in the truck frame, so about one hour would be shaved off the install time. The # DM8550034 is compatible with industry...
view full answer... - 5th Wheel Rail Kit and Hitch Recommendations for a 2022 Ford F-150 with a 5-1/2 BedYes, the Curt Custom Fifth Wheel Installation Kit # C93WR will fit the 5-1/2' bed on your 2022 Ford F-150 and you can use the Universal Wiring # C57008 for an easier time connecting your wiring. When it comes to a 5th wheel hitch we need to look at a stationary one though because you won't have enough clearance for a standard sliding 5th wheel hitch - you need to use a stationary hitch with a replacement pin box that has a rotating turret so you trailer doesn't make contact with your truck...

I recommend the B&W kit and Companion hitch. The insall kit for your for your 2018 Ford F-350 is part # BWGNRK1116-5W. I like the B&W kits because the fifth wheel install kit is actually a gooseneck hitch in case you ever need it in the future. It's also an underbed kit so you don't have the fifth wheel rails taking up space. Then for the hitch that fits into the B&W kit use the fixed Companion, part...
view full answer... - Weight of Curt C16180 A25 5th Wheel Hitch for 2022 Ford F350 With OEM Puck SystemThe Curt A25 5th wheel hitch you'd looked at, part # C16180 weighs about 120 lbs, and the necessary # C88KR base rail to puck adapter weighs right at 70 lbs. The hitch is a bit heavy, but its weight can be significantly reduced by removing the hitch from the head, which is done by pulling one clevis pin. This breaks the hitch down into two pieces that are more easily handled. If you'd like to install a 7-way in your truck bed so you don't have to run the trailer connector up over the...

That said, there is a way to determine the clearance, though you will first need to add a gooseneck hitch and offset hitch ball, which are the following: - B&W Turnoverball Underbed Gooseneck Trailer Hitch with Custom Installation Kit # BWGNRK1116 -...

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.

In addition to the hitch you will also need the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C57008. This plugs in-line with your factory 7-way and will provide you with a connector in your bed to hookup your trailer wiring.

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.

The adapter drops into the pucks, which might require a little fiddling to get adjusted the first time, but once adjusted it'll lock down into the pucks perfectly. Then, mount the hitch to the adapter just like you would to a regular bed rail. If you don't already have a 7-way trailer connector set up in the truck bed, you can install one using part #...

To make plugging in and unplugging faster and easier I recommend the # C57008. This wiring harness will plug directly into your factory 7 way and allow you to reroute your plug to the bed of your truck for ease of access. Doing this does not get rid of the functionality of your factory 7 way at the rear of your truck.

With both of these models, you will need the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552028-71 to complete the installation.
