Video Transcript for Demco Fifth Wheel Installation Kit DM6194 Review

Speaker 1: Today, we're gonna take a look at the Demco fifth wheel rail adapter for the Chevrolet and GMC OEM fifth wheel towel prep packages. This has a 21,000 pound weight capacity. Now this is a custom fit part. It is designed to fit the 2016 and new Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks with the 6 1/2' bed and the factory rail kit. Basically, this part will convert your factory installed under-bed fifth wheel mounting kit from Chevrolet or GMC. It's a standard above-bed fifth base rail, basically to let you use your fifth wheel trailer hitch that would normally attach to this standard above-bed rails.

This part does mount very easily, mounts to the OEM pucks or sockets in your truck bed. Basically, there's a tab right here, one on that side, one on that side, one on that side, and then the very middle, there's a post. So basically, what you'll do is this will drop into the pucks. The post center here, if you turn this, it'll lock it into place. Then you just put your thumb screw on their and tighten it down to hold it into place.So once you get that started, just go ahead and tighten it down all the way and then it'll lock that post into your under-bed system.

There's no drilling or welding required. The finish on this, it's a rust resistant black powder coat steel construction. Part is made in the USA. Again, the maximum capacity on this is 21,000 pounds, so again, when you go to install this, you'll just right up here at this end and over there and then back here, those four corners will drop into the pucks. The post will drop into the middle hole.

Like I said, you just turn this, line it up, and then tighten that down to lock it into place and you're already to go. Your fifth wheel will drop right into the rails. But that should do it for the review on the Demco fifth wheel rail adapter for Chevrolet and GMC OEM fifth wheel towel prep packages. This has a 21,000 pound weight capacity.

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. 557890

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. 582330

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 553122

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. 600784

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. 488212

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. 651862

Product arrived in just 2 days. Very pleased with the item and the quality,This thing is heavy duty. Fit perfect just as advertised. I liked that the 4 legs were adjustable, allowed to level it with the bed. Only negative was it did not come with the bolts that go in the center pin to lock in place and no instructions, but there are videos on line that show the instructions. Still give it 5 stars! 615044



- DM6194
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. 612296

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! 607378

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. 590659

2018 Chevrolet Silverado 2500

It arrived lighting fast. I had it installed in less than 21 hours from when I ordered. It was falling out of the box when it arrived however there wasn't any damage. The legs are round however my 2018 truck pockets are slotted. I called customer service and assure that was by design and weight of the trailer prevents movement. Also the rear legs dont sit in the rear pockets again by design. The plate is held down in the gooseneck slot. It's seems well made. 564391

  • 5th Wheel Hitch Compatibility with GMC OEM Puck System for 5th Wheel Prep
