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!

  • Rail Adapters Confirmed to Fit a 2019 GMC Sierra 2500 With Factory Prep/Puck System
    For your 2019 GMC Sierra 2500 the correct rails will depend on your bed length as the Adapter Rails # C88KR will only fit the 2020 and newer Chevrolet and GMC Heavy Duty trucks with the Prep/Puck system. For an 8' long bed you will need the Demco 5th Wheel Rail Adapter # DM6206. For the 6-1/2' short bed either the Curt Adapter Rails # C16023 or Demco 5th Wheel Rail Adapter # DM6194 will be the one you need.

  • Recommended 5th Wheel Adapter Rails for Ford, Chevy, GMC, and Ram Factory Prep Package Puck Systems
    Depending on what truck brand you are looking at will determine what adapter rails you need for your Husky hitch to be compatible. Each factory prep package is slightly different so the adapters are not interchangeable. If your new truck is a Ram, then you will want the Reese adapter # RP30154. If you new truck is a Chevy or GMC, then you will want the Demco adapter # DM6206 for an 8 foot bed or # DM6194 for a short bed. The two adapters are not interchangeable between bed sizes. If...

  • Fit of Reese 20K Select Plus Hitch RP30928 in 2018 GMC Sierra 3500 with Factory Rail Kit
    The Reese 20K M5 5th Wheel Trailer Hitch # RP30928 is designed to fit into industry-standard above-the-bed base rails like those in custom rail kit # RP50066-58 and universal-fit kit # RP30035. These kits differ in their price and overall installation time (the custom kit costing more and taking less time) but they both use the same industry standard above-bed rails. Any brand of standard hitch will fit into these base rail kits. For a Sierra 3500 with the factory under-bed 5th wheel prep...

    For your 2019 Chevy 1 Ton Dually with OEM pucks I recommend the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 8' Bed - 21K # DM6206 which will give you the industry standard rail footprint for the vast majority of 5th wheel hitch compatibility. I've attached a photo to assist. When not in use, the bed will still be clean with just the OEM pucks. If you don't already have the in-bed 7-way, I recommend the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree...

  • Factory Prep Package Puck to 5th Wheel Rail Adapter for 2021 Chevy Silverado 3500
    The # DM6206 you mentioned only fits 2016-2019 GM trucks with the 8 foot bed. From 2020 onward, GM changed the layout of the puck system. For the 2021, you'd use the # DM6333 rail adapter. After an initial adjustment, the adapter would drop into the factory pucks and be secured. The adapter provides bed rails with industry standard hole spacing. If you click the provided link, you can see a product demonstration video featuring the Demco # DM6333 adapter.

  • Which Demco Rail Kit Fits 2019 GMC Sierra 3500 with OEM Rail Kit
    For your 2019 GMC Sierra 3500 you'd need the Demco rail kit adapter part # DM6206 as the # DM6333 fits the newer GM rail kits and would not work for you. This would work with the Andersen Ultimate part # AM3200 that you asked about as well.

    The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 8' Bed # DM6206 is secured in place by the gooseneck hitch lock position as you stated. The 4 other corners of the adapter also help hold the adapter in position and have 2 different shapes. These don't lock, but do keep those 4 corners tight.

  • Do Curt Q25 Grease Fittings Break Easily and How Does Demco Adapter DM6206 Install in 2018 Silverado
    I combined both of your questions into one. There were some issues with the Curt Q Series hitches including # C16069. Those issues have been addressed though in the form of a new series of hitches; the "A" series. The A25 is # C16066. Damaged shipping cartons occur when the delivery service handles the packages. Heavy items can sometimes get tossed around and the boxes get damaged. The packaging is not damaged when it leaves our warehouse though. On the Demco adapter # DM6206 there is...

    You can install any brand of industry-standard 5th wheel hitch in the Demco 5th Wheel Rail Adapter # DM6206, including one like the Reese shown in the linked photo. 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. Since your hitch is a slider and you have a long bed truck you will not need to release the slide mechanism for making...

  • Can I Use B&W Patriot Sliding Hitch In 2018 GMC Sierra 3500 With Prep Package
    There are normally adapters to fit the B&W Patriot sliding hitch part # BWRVK3270 to factory prep packages, however the only adapter available part # DM6206 for the 2018 GMC Sierra 3500 long bed is not compatible with the Patriot because the cross section of the adapter interferes with the sliding mechanism of the hitch. There is also not an interchangeable base available that fits the prep package at this time. The only option is to replace the fifth wheel with a fifth wheel that fits...

  • 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. Either of these options will fit in the OEM puck system in your truck. I included videos for both of the products mentioned for you to take a look at.

    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.

    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.

  • How to Tell if 2019 Chevy Silverado 2500 has OEM Rail Kit
    The OEM rail kit/package that your 2019 Chevy Silverado 2500 could have came with would look like 5 pucks in the bed of the truck that a hitch would fit into. If you look into the bed of your truck and you don't see any mounting hole you wouldn't have it. Most likely you'd know if you did though since they are pretty noticeable. I attached a picture that shows what it looks like for you to check out as well. If you don't have the OEM rail kit the Curt kit part # C16411-204 is the correct...

  • Correct Demco 5th Wheel Rail Adapter for 2017 GMC Sierra 3500HD with 8 Foot Bed
    The correct Demco 5th Wheel Adapter for your 2017 GMC Sierra 3500HD with the 8 foot bed is the part # DM6206. This will drop right into the factory pucks on your truck bed to provide industry standard rails that are compatible with most 5th wheel hitches on the market. The Demco Adapter # DM6194 that you referenced is only a fit for the 2017 Sierra that has the shorter 6-1/2 foot bed. The puck configurations on the two bed sizes are just a tad different requiring different adapter designs.

This adapter will mount directly to the factory pucks in your truck bed to provide industry-standard base rails that the Husky hitch will attach to. If you happen to have the 8 foot bed, you will instead need the Demco Rail Adapter # DM6206. This will work exactly the same as the above mentioned adapter, but it is...

  • 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.

  • Can One Fifth Wheel Hitch Be Used in Ford and GMC Trucks with Factory Rail Kits
    If you used the appropriate rail kit adapter in each truck you'd be able to use the same fifth wheel hitch. For the Ford truck you'd need the part # RP30156 and for the GMC 3500 you'd need the Demco adapter part # DM6194 for if you have a short bed truck or part # DM6206 for if you have a long bed. If the trucks have short beds you'd need a slider like the Reese part #RP30075 or if you have a long bed truck you'd want the # RP30047.
