I needed a little help moving the item. It weighs about 200lbs. Very easy installation. Took about 30 minutes. Put my 5th wheel hitch onto the product and pinned it down. Great item!!

The product has exceeded my expectations. I have had no problems with this product at all. I is low profile enough that when I take out my 5th wheel hitch I do not have to remove the Demco product.

Gave my review elsewhere, but didn’t see a place to add pics. This is adapter was a perfect fit to my 2019 Chevy 2500HD 6-1/2’ bed truck, and allowed use of my Reese Pro Series 16K fixed hitch. It’ll work great towing my 10,000 lb. camper. The only thing to pay attention to is that the thumbscrew used to lock the lever in place after the adapter is installed, is ONLY a THUMB screw. I attempted to give it a final snug with a tool and it snapped right off.

I needed an adapter plate if i was going to utilize my old Reese sliding fifth wheel hitch.
It arrived in very short time . I was skeptical it would be able to securely be able to do the job. 1200 miles later i was home again. It worked great. I currently have it for sale as i have purchased a newer truck and the hitch or plate are compatible.
Great product though.

2018 GMC Sierra 2500

etrailer kept me informed as to the delivery status of my order and I was very please to receive the Demco adapter base for my 2018 GMC 2500HD a week early! The install was simple.

My only issue was the rear Demco product leveling studs that rest on the truck bed pucks were not the same thickness and that caused me some install delays. (See Photo.) etrailer, please let Demco know of this issue so they can improve.

Once I saw this I worked around the issue. Otherwise very well built product that saved me from having to buy a new 5th wheel hitch when I bought the new truck.

2018 GMC Sierra 3500

The demco hitch adapter arrived earlier than expected. Packaging was crap but it fit perfect and was real easy. I did sand & repaint the entire assembly. I also put on the new decals you sent me. (Thank you). When I need additional stuff you will be the company I contact

Fits perfect in my 2019 Silverado 3500hd. The bottom rear feet are not pins. They are flat that you adjust with a supplied Alan wrench. Pin the middle and adjust the feet to keep from rocking back and forth. Side to side. Fits my Reese 16k hitch nicely.



by:

Dropped right in and fit great. Very easy to install. Installed to hold my 16k Pullrite Superglide in my factory 5th wheel prepped 2018 GMC Sierra 2500.



by:

Great product well built fit perfectly made my slider hitch install a breeze



by:

Install was easy, product is as advertised and seems pretty beefy. Only Issue is the Wing Nut to lock it is a weak metal. There appears to be a bit of overspray or extra material making it difficult to get the screw in. My Wing nut sheared off when trying to get it locked down. Luckily I had a Steel Machine Screw with the same dimensions that I used in the second hole.



by:

So far, So good, my adapter came two days after placing my order. Had it in in a few minutes, set my Huskey fifth wheel slider on it and was finished.
Thanks, for a great product.

We just got it today, but it went in easy and can't wait to start pulling camper this summer! Shipping was fast! Thanks

Perfect fit packaging was fine arrived on time absolutely phenomenal system. Jesse M was a fantastic customer service representative explained a lot of stuff to me once it arrived installed within 15 minutes.



by:

Was impossible to locate 5th wheel rail mount to fit fit my new 2019 GMC Denali built-in puck system until I called Donna P. at etrailer. The rail fits into all five holes pre-designed and built into my truck bed. Made a heavy-duty construction much heavier than the double rails normally used in truck beds it is certain to last a lifetime. The new Reese Hitch was just as impressive. Thank you Donna!

The Demco rail adapter arrived at our house less than 48 hours after I placed the order. It fit perfectly in our 2018 Silverado 3500, and I was towing our fifth wheel the next day. Everything works as advertised. Thanks to Pat at e-trailer for answering my questions and helping me place our order.

The product arrived as indicated and fit my 2017 GMC Sierra 2500 as stated. I wiil be putting my fifth wheel on this hitch plate and pulling my Columbus 320RS the week before Thanksgiving. I so glad I did not have to drill hples in the bed of my truck. This adapter fit the factory holes for the removable gooseneck set up.



by:

The service I received was exceptional!!! They came in to help me with a small glitch after hours. I would highly recommend etrailer. My Demco 5th wheel rail adapter has really been a great product.

GMC Sierra

Arrived on time, quite heavy though, but after all it's rated for 21,000 lbs.. Fit my new GMC 2500 Sierra with 6 1/2' bed and underbed 5th-wheel towing prep package as promised. Very easy installation and fell right in the prepared opening in the truck bed. More important was that it fit perfectly the 15k PRO Series 5th wheel hitch we already owned. All in all, great product and installed within 1/2 hour.



by:
2017 Chevrolet Silverado 2500

I like the product. However the leveling pucks were to high to allow the locking pin engagement. I had to grind down the four treaded pads on the plate to raise the pucks. I'm not sure if it was weld slag or the paint that caused the problem. Also there was paint in the treaded holes for the 1/4 - 20 wing nut which prevented the install of the wing nut. I had to chase the treads. I hope that this product will give me may years of good service.



by:
2019 Chevrolet Silverado

We installed it in a new 2019 Silverado 3500 that had the 5th wheel preparation package. It only took about 10 minutes. Then, my 5th wheel hitch from the prior truck attached easily to this new rail system. No need to pay someone to install. Very pleased!



by:
2018 GMC Sierra

I received the Demco puck system hitch adapter for my 2018 GMC Sierra 2500 on August 24th at about 8:00 pm and had it in my truck by about 8:15 pm. The hitch adapter is well made and was extremely easy to affix to my truck. It is a very heavy duty adapter. I couldn’t be more pleased. Definitely a good buy.



by:
Chevrolet SS

Very fast shipping and hitch plate was great quality. Very heavy duty. Was missing thumb screw to lock the hitch into the goose neck hole, but I remedied with a better option by using a hex pan head SS screw and lock washer. This made it more vandal resistant, i.e someone could not just unscrew the thumb bolt and remove the hitch adapter without an allen wrench.

  • Can The B&W Patriot Be Mounted To Adapter Rails For GM's Puck System
    Hey Tom, The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package # DM6194 would fit your 2019 GMC Sierra 2500's puck system, but the design of the B&W Patriot Slider # BWRVK3270 will prevent it from being able to be mounted to adapter rails like this one. You would unfortunately need to switch to B&W's Companion slider # BWRVK3770 in order to utilize your puck system. I would see try to sell the Patriot to recoup some of your cost to transition over.

  • Recommended 5th Wheel Hitch for 2019 GMC Sierra 2500 with Puck System
    I would be happy to help you select your first 5th wheel hitch for your 2019 GMC Sierra 2500! If you have an 8' bed then you don't need a slider and I recommend the 20K B&W Companion # BWRVK3700 because it has 1" thick dual jaws to secure your king pin and a cam-action latching handle that allows you to release your 5th wheel trailer even if you're parked on uneven terrain. The 20K rating is more than enough for your 12K trailer and since this is made in the USA and comes with a limited...

  • Autoslide 5th Wheel Hitch Recommendation for 2019 GMC Sierra 2500 with Factory Pucks
    We have exactly what you need! For your 2019 GMC Sierra 2500 I recommend either the 18K Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550034 or the 21K Hijacker # DM8550035. The only real difference between the two models is their towing capacity. The Hijacker features an automatic slider to provide cab clearance with your short bed Sierra without having to get out of the truck. It also has a premium wraparound single-piece jaw that will provide an excellent connection with the...

  • Reese Hitch and Sidewinder Recommendation for 2019 GMC Sierra 3500 Short Bed with OEM Rail Kit
    Since we know you have a Rota-Flex pin box on your trailer we also know that there is a Sidewinder that can fit as a replacement. We do need to know more info though to determine which specific Sidewinder you need. You'll need to look for an LCI number like 1621, 1116, 1716 etc. and we'll know which is the correct fit. If you have a Lippert 1621, 1621HD or 0719 you'd want the part # RP34FR. If you have a Lippert 1116, 1716 or 0115 you'd want # RP77FR. So the other part of this that gets...

The center connection will give you the towing you need and the 4 puck locations even though they don't lock in the pucks will minimize any excessive movement of the hitch.

  • Fifth Wheel Rail Kit Adapters for 2018 GMC Sierra 3500 with Factory Rail Kit
    What's interesting about the GM fifth wheel rail kits in the 2018 GMC Sierra 3500 is that the pucks are different widths apart based on the length of the truck bed. So the Demco 5th Wheel Rail Adapter part # DM6194 fits the short bed trucks and then for the long bed trucks you'd want the Demco 5th Wheel Rail Adapter part # DM6206.

  • Is There An Adapter To Mount A B&W Patriot Slider 5th Wheel Hitch In A 2022 Ford F-450 W/ OEM Pucks
    Hey Kevin, Unfortunately due to the design of the Patriot's # BWRVK3270 slider base it's incompatible with adapters. The crossmember (seen below) sits lower than the rails and would compete for the same space as the center of the adapters. You have two options going forward: Option 1: You replace the slider base of your Patriot with the fixed base # BWRVB3255 and then use an adapter like the Curt # C88KR to mount the hitch to your factory puck system. Since you have an 8' bed you won't...

  • Can B&W Patriot Slider Be Used With Ford Puck System?
    Hello Kevin, thanks for reaching out. So, there are rail adapters that will fit into the puck system in your 2022 Ford F-450. The problem is that none of them will work with the B&W Patriot slider. For example we have the Curt Adapter Rails # C88KR which fits into the Ford puck system, but the placement of the turn handles and the crossmember connecting both rails obstructs the Patriot slider, so they will not work together. Sadly, there is no way to use the patriot slider with the Ford...

Both of these are rated for up to 21,000 lbs and will give you the industry standard rail locations for the hitches compatible with the horizontal bed rails.

Curt is one of the hitches that uses legs compatible with the different pucks, so I will give you both options. For a Ram, you will use Reese adapter # RP30154 or Demco # DM6099. You can alternatively use the Curt legs # C16021 which will mount directly to your pucks. For a Chevy or GMC, you will use the Curt OEM 5th Wheel...

  • Tips for Demco GM OEM Rail Kit Adapter Stuck in Truck Bed
    Sounds like something is binding in the pucks/hitch tube or one of the releases is still stuck. Have you tried hitting the portion of it that fits down into the hitch with spray lube at all? One trick that helps others in similar situations is to put a hitch in the adapter and then put the pin weight of a trailer onto it and then try to release the rail kit as this normally allows the mechanism to fully release. From there you can remove it from the hitch.
