Very easy to install. But it would be a whole lot easier if they made it shorter. You have a lot of extra wiring harness you have to wrap up tie up out of the way.

2026 GMC Sierra 2500

Product fit perfect . The only two negatives are it showed up later than it said when the order was placed. And the box was beat up and the hardware was loose in the box. The hardware started out in a large bag but it tore open and spread everywhere. Lucky only one nut had escaped the box. But even that was a hassle to locally source a shouldered nut of that size.



by:

This works great! Easy to install. I would ask that a small tube of dielectric grease be included.
Thank you for another GREAT purchase from Etrailer.com

I ordered and paid for expedited shipping. Although I have finally received my product it is 2 weeks or longer past the time I needed it. I realize that shipping is not always your issue but I started receiving “how was your product” and “rate your product” literally weeks before I received it. I had a time frame that I would have time to do this job and that time frame has come and went a long time ago. If you guys can’t handle the logistics, use [online vendor] to market your goods.



by:

Easy to install plug and play works per fectly.



by:

The product itself is quality and works as advertised. Mine didn’t come with the cover plate. Shame on me for not reaching out to etrailer, I assumed I misread the product and bought the cover plate off Amazon. Don’t be like me and pay another $7 you shouldn’t have had to.



by:

Easy Peasy install! Knock out the useless factory cover and thread the wires in, mount the connector to the truck bed and route the wires.

Recommend having the spare tire out of the way and getting some of the dielectric grease for the connection underneath. This kit has everything you need to get the job done. Very Happy etrailer sells this.

Super easy install, takes like 10 minutes tops. Included all the screws and zip ties you might need.



by:

Really simple and straight forward install. Didn't have to drop the spare tire or remove a tail light. My truck had the hole pre-drilled so it was a simple remove the cover in the bed, route the wires, make the lower connections and done.



by:

It worked great. I didn’t have to cut or splice anything. Just plug and play. Love it



by:

Product was a great factory fit for my 2022 GMC 2500hd. Install was straightforward. A little dielectric grease on the connections and zip ties to hold up the extra length and we were all set. The toughest part was trying to get the spare tire down to get more working room as the key fitting for the tire was corroded and had to use spray to loosen it up!



by:

Easy install the only thing that would make the kit better is to supply dielectric grease along with it

Used to to wire in my FourWheel Hawk camper on my new 2024 Chevrolet 2500hd, very easy to use and eliminates running wire from camper to truck battery. Since I converted my 12 volt batteries in camper to lithium, I do not tie them into truck battery.

2022 Chevrolet Silverado 2500

I was mad when I saw this, paid $200 to have installed in my previous truck’s bed. When I watched the video and saw it was plug and play I ordered and installed my self in less than 30 minutes. Shipping took a week but I won’t need it until the 3rd week of August when I head out with the fifth wheel. Product came as advertised with every thing needed to install. It looks factory (see pic). I am very happy with how it came out and the installation video was excellent.



by:

Ordered this for a 2024 Silverado 2500HD even though it wasnt certain that it would be compatible. Once i figured the connections out the actual install took maybe 15 minutes! Ill add i coated all the connection pins with dielectric grease before reconnection. Worked perfectly.

Installed like should. Can’t say it was effortless but it was doable. Works flawlesssly. Very satisfied.

  • Best 5th Wheel Hitch For 2024 Chevy 2500 4dr Crew Cab With 6-3/4' Bed
    Hey Justin, I can definitely help with this. I do recommend going with a sliding 5th wheel hitch since your truck is not a long bed. The slider helps with clearance on tight turns. What I recommend is the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775. This is made specifically for the factory pucks in your Chevy, so installation is simple. The slider allows for 12" of front-to-back travel. Overall the B&W hitches are super solid. The head is fully articulating so you get smooth...

  • Recommended 5th Wheel Rails and Brackets for a 2025 Chevy Silverado 2500
    Hey Jenna, welcome back! To add a set of 5th wheel rails to your 2025 Chevy Silverado 2500, I recommend the B&W Custom Installation Kit w/ Base Rails item # BWRVK2505. This set of rails are industry standard and are definitely compatible with Andersen Ultimate 5th Wheel Hitches like item # AM3200. The brackets included with the B&W item # BWRVK2505 are custom fit and install in pre-existing holes in your Silverado's frame. They fit the both the 6-3/4' and 8' bed lengths and include all...

  • Parts Needed to Use Andersen Aluminum Ultimate in 2025 Silverado 2500 Without Prep Package
    Hey Adam! All you need to use the Andersen Aluminum Ultimate 5th Wheel Connection 2 Gooseneck # 3220 is a gooseneck hitch. The best option is going to be the B&W Turnoverball # BWGNRK1020. The Turnoverball allows the ball to be stored upside down so you have full bed access when not in use. It also gives you the option to use the B&W Companion # BWRVK3500-5W if you ever decide you want to use a traditional 5th wheel hitch. Then for a 7-way in your bed you can use the # C53CR which plugs...

  • Recommended B&W Turnoverball Gooseneck Hitch for a 2022 GMC Sierra 3500
    No, I am sorry it will not. Your B&W item # BWGNRK1012 stops fitting the Sierra 3500's after 2019 when GM changed the frame size. For your 2022 GMC Sierra 3500 you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch item # BWGNRK1020. I have linked an installation video below to help you get it set up. To make towing with a gooseneck or 5th wheel trailer easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way...

  • 5th Wheel Rails and Hitch for 2021 Chevy Silverado 2500
    Hey Nicholas! What exactly are your questions? If you're looking for a complete kit with rails and a 5th wheel hitch I recommend the B&W Patriot 5th Wheel Trailer Hitch w/ Slider # BW67XR. This comes with a custom base rail kit for your Silverado along with the Patriot slider so you have clearance for turns with the standard bed. If you don't have wiring in the bed you will also want the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C53CR. If you have a different question, or you're...

    Congrats on the new truck! Since you have the shorter 6-3/4' bed in your new 2025 Silverado 2500 it is recommended to go with a slider hitch like the Curt A16 item # C16521 you referenced. This will give you the proper turning clearance so you don't have to worry about hitting your truck when you're making tight turns. There's two different configurations of this hitch depending on whether or not your 2025 Chevy Silverado 2500 came with the factory puck system or not. I have listed them...

  • 5th Wheel Hitch for 2022 Chevy Silverado 2500 Towing Keystone Cougar 26RKE
    Hey Thomas! For a 5th wheel hitch I recommend going with B&W. Their hitches are well built and reliable so you'll have a great towing experience. If you have the prep package you can use the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775. If you do not have the prep package I have two options. The first is the B&W Patriot 5th Wheel Trailer Hitch w/ Slider for Chevy/GMC # BW67XR. This includes the above bed rails you will have to install in your truck to mount the hitch. The...

  • Can I Add A Second 7-Way Outlet To A 2024 Chevy Silverado 3500HD?
    Hello Terry and Pam, thanks for getting in touch. So we do not have any kind of 7-way that would have two outlets. The best way to do this would be to add a 7-way to the bed using part # C53CR. This way you can have the factory 7-way on the back bumper, and another 7-way in the bed. This is the only way we are aware of to safely add a second 7-way outlet to a 2024 Chevy 3500, or any truck for that matter. Reply below with any other questions or comments and I will get back to you.

  • Do You Have a In-Bed 7-Way Connector w/ Camera Inputs?
    Hey Rex! Sorry, we do not carry anything like that. What you're describing sounds like the Trailer Tow Harness Connector 13530416, which is a GM OEM part. I have never seen it come with the in-bed 7-way connector like the Curt item # C53CR, you referenced. What you would need to do is source that connector from a vendor who carries OEM parts and then pair it up with the Curt item # C53CR. They both use the USCAR 7-way socket which is that circular connector. It's been standard amongst...

    Hey Rob, I can help you get what you need for your 2020 GMC Sierra 2500 to install the Demco # DM6077 hitch. I assume when you say "no mounting" that you don't have the side plates for the hitch, or the base rails for your truck. So with that in mind, here's what you'll need: - Replacement Side Plates for Demco Autoslide 5th Wheel Trailer Hitches # DM6003 - Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck # C16429-204 The side plates will attach to the # DM6077, and the...

This gooseneck hitch is custom fit for the 2026 Chevrolet Silverado 3500's without the tow package. It fits both the long and standard bed models.

Since you're driving such a newer truck and using a Reese 16k hitch already, I seriously doubt the rail system you have is old enough to not be compatible with the Patriot hitch.

  • Troubleshooting Trailer Backup Light Not Working After Installing Curt 5th Wheel/Gooseneck Wiring
    Hi Richard; have you tried testing the pin on the Curt 5th Wheel/Gooseneck # C53CR 7-way for power? I would start there. Since the light works on your trailer with the 7-way at the bumper I expect it to work with the gooseneck wiring as well. If you don't have power on the reverse light pin I would double check the connections. Go ahead and unplug the wiring and plug it back in to make sure everything is properly seated, this is likely the issue. This includes the connector in the truck...

    Hey Zach, thanks for all the information. Since your 2020 GMC Sierra 3500 has the B&W Turnoverball item # BWGNRK1020 installed you'll need to use the B&W Companion item # BWRVK3500 and lock out the Reese Revolution pin box so it doesn't rotate. Locking it out will turn the Revolution into a standard pin box and there's no compatibility issues with it and the Companion item # BWRVK3500 when you do this.
