Awesome product. When I bought my new Silverado thinking that I would have to buy a new 21K hitch to tow my 5th Wheel but this took care of that issue and saved me a lot of money. Built solid, easy install.



by:

If you own a fifth wheel hitch already and purchase a truck with the puck system this is the way to go. Saves you money and works like a champ.

2017 Chevrolet Silverado 3500

I needed an adapter for my 2017 GMC 3500, found the Demco DM6206, very well made and very heavy. Fit like a glove in my truck. Well pleased with the purchase from etrailer.



by:

Product dropped right onto truck and Hensley hitch pinned in nicely. I’m a little disappointed in the “slop” though. The adapter is secured by the goose neck hole and wobbles on the 4PUC holes with @1” slop. Camper is secure but it’s annoying

Demco has since made a design change that allows the feet that fit into the truck bed pucks to be tightened up. If you have the older model that did not allow for this adjustability which is what it sounds like, Demco offers a shim kit which Ill have them send out to you.



by:

After I received the adapter and installed my Demco hitch, I did not like the way it fit. There was some pivot between the hitch and the adapter plate, about 1/4 in. even thought the pins went in to secure the hitch to the adapter, I did not feel comfortable. I bought at Curt hitch and did away with the Demco hitch and Demco adapter.
I bought all these product from etrailer and was very please with the purchase process and shipping.



by:

The product was delivered very quick has usual with e trailer but I had to make some modifications to my Spyder gooseneck hitch so it would fit down all the way so I could get pins in the adapter and Kaylyn was awesome to work with easy to talk too so it was a good experience overall



by:
2018 Ram 3500

Great fast shipping. Product fit perfect in my 2018 GMC 3500 with OEM underbed hitch system. My Reese 20K 5th wheel hitch also fit perfectly into the rails. If you are looking to put older style rails in your newer truck and use your older 5th wheel hitch this is what you want. Very well made product and also heavy duty. Weighs about 100lbs plus hitch weight. I would definitely recommend product and etrailer to anyone. Very helpful getting you safe and back on the road to more camping and towing.



by:

Made moving 5th wheel hitch to new truck very easy, quick to remove and there are no rails that stay in the bed of your truck



by:
2017 Ram 3500

Just received the hitch adapter today. It is heavy and so far seems like it will work. Have a concern about the one point locking but I have seen no reviews stating anyone had problems. Would like to see four corner locking with the same adapter. I tow a trailer around 13000 lbs loaded so we are wanting to try it out. Will report on it after I get a chance to use it. E trailer is a good company to deal with.



by:

works fine. Has a little wobble from corner to corner and rattles a little. Once hocked up to 5th wheel the weight takes away any rattle and wobble.



by:

Just installed my adapter (quick and easy)! etrailer service was out standing (1st time doing business) intend to do a lot business with these folks.

2019 Chevrolet Silverado 3500

Great product. It was so easy to put in my new Chevy I had to read the instructions 2 more times. Ordering thru E-trailer was also a great experience, help getting the correct order for my truck and it came when promised. Will definitely use them again when the need is there.

The craftsmanship is excellent and installation was a breeze. Well done!

  • Recommendations for 2018 GMC Sierra 3500 5th Wheel Setup
    The GMC integrated brake controller on your 2018 GMC Sierra 3500 may or may not work with your EOH system. Previous model years have required an adapter like the HydraStar # HBA-CAM to function well together. The Pull-Rite Auto slide hitch will work in a standard bed of the GMC truck. You don't need a sliding hitch with an 8 foot bed, but you would with the 6-1/2 foot bed. For either bed size, I recommend the custom bed rails # RP50066-58 for industry standard above bed rails.

  • Converting Curt Q24 Sliding 5th Wheel Hitch To OEM Puck System on 2018 GMC Sierra 3500
    Thank you for all of the info! There are a few different options for using your sliding Curt Q24 # C16546 with the puck system on your 2018 GMC Sierra 3500. If you have the short bed then you need the Adapter Rails # C16023 but if you have the long bed you can either use the Adapter Rails # DM6206 to retain the sliding feature (for future use) or you can swap out the slider for the Stationary Legs # C16025 which drops your Q24 straight into the pucks on your pickup.

  • Fifth Wheel Rail Adapter For 2018 GMC Sierra 3500 With Factory Puck Prep Package
    It sounds like you want to adapt the factory towing prep package in your 2018 GMC 3500 8 ft bed to be able to use your Reese fifth wheel hitch that attaches to industry standard fifth wheel rails. If that is what you are trying to accomplish, you need Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package part # DM6206. There is a not a Reese brand adapter available for the GMC but the Demco adapter drops into the puck holes in your bed and allows you to use your standard...

  • Using a Reese 20K Round Tube Slider 5th Wheel Hitch in a 2018 GMC Sierra 3500 w/Factory Prep Package
    As long as your 2018 GMC Sierra 3500 is a short bed you can use adapter # C16023 with your Reese 20K hitch with round tube slider. If your truck is a long bed the above adapter will not fit due to differences between the short and long bed versions of the factory prep package. Assuming your factory prep package includes the gooseneck hitch as well you can use adapter # DM6206 with your Reese hitch on the long bed model. Installing any other 5th wheel installation kit would be a major...

  • Will a Andersen Ultimate 5th Wheel Trailer Hitch Fit into the 2018 GM Factory Puck System?
    I assume you are referring to the Anderson Ultimate Connection item # AM3200 you were looking at. This will fit your 2018 Chevy Silverado short bed but you will need to use the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package item # DM6206.

  • B&W Companion Slider Over an Anderson Hitch for 2018 Chevy Silverado 2500 Short Bed w/ Puck System
    I have a solution for you but the only way to use an Anderson Hitch, like the item # AM3200 you were looking at, with a 2018 GM puck system is to use the the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package item # DM6206. They do not make Anderson hitches that mount directly to the OEM pucks on your 2018 Chevy Silverado 2500. If you are not interested in using a rail adapter then I recommend the B&W Companion OEM 5th Wheel Hitch w/ Slider item # BWRVK3770. This...

  • Will The Demco 5TH Wheel Rail Adapter Fit Both Short and Long Bed Versions of a 2017 Silverado 2500?
    For your 6-1/2' bed on your 2017 Chevrolet Silverado 2500HD Duramax you will need the Demco 5th Wheel Rail Adapter # DM6194. Since the Demco Adapters drop into all 5 mounting points of the factory prep/puck hitch system you will need this adapter as the gooseneck ball sits in a different position on the short bed. You can see that the Demco 5th Wheel Rail Adapter # DM6206 for the 8' bed has more of an X shape where as the short bed has a more y shape frame accounting for the difference...

    It sounds like you're looking for a way to use your older Reese 16k hitch that fits in industry standard base rails in the puck system of your 2019 Chevy Silverado 2500. The best solution for this would be to use an adapter like the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package part # DM6194 for 6-1/2' bed or part # DM6206 for 8' beds. This adapter drops into Chevy/GMC OEM prep package pucks and provides you with industry standard base rails to mount a 5th...

    What Reese hitch - the model number - do you have? It may be possible to switch out the legs or use an adapter. But to know for sure I would have to know the model number of your current Reese hitch. If you can let me know I'd be happy to help.

This adapter drops into the factory prep setup for Chevy/GMC OEM 5th wheels and provides the equivalent of standard base rails that will accept any ISR (industry standard rail) type hitch up to a 21K rating.

  • Available 5th Wheel Adapter for 2008 Chevy Silverado 3500 with 8 Foot Bed and Aftermarket Prep Pkg
    According to everything I'm seeing, the 2008 Chevy Silverado 3500 did not come with factory pucks, so this is most likely going to be an aftermarket type puck kit. If the pucks have a gooseneck installed and are installed in the same manner as the 2016-2019 Chevy Silverado 3500 with OEM Prep Package then you can use the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 8' Bed - 21K # DM6206.

If you are sticking with Chevy for your dually, then you will most likely want the Replacement Base Legs for Reese 5th Wheel Trailer Hitch # RP30727 since you don't need the slider base and then Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 8' Bed - 21K # DM6206.

  • Recommended 5th Wheel Rail Adapter To Use Reese Slider Hitch In 2017 GMC Sierra 2500 W/ OEM Prep Pkg
    As long as your Reese Slider Hitch is compatible with industry standard rails you will need the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 6-1/2' Bed - 21K # DM6194 if your 2017 GMC Sierra 2500 has the 6-1/2' bed, or # DM6206 if it has an 8' bed.

    The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package will definitely sit in all four pucks and locks into place inside those pucks. It is possible you may have ordered the wrong adapter, which is why it isn't fitting. The Demco 5th Wheel Rail Adapter # DM6194, which is what you have, only fits if your 2017 Chevy Silverado 3500 has a 6-1/2 foot bed.
