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. 672067

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. 747315

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! 707696

  • 5th Wheel Hitch Compatibility with GMC OEM Puck System for 5th Wheel Prep
    There is not an adapter for the 15K Hitchhiker 5th wheel hitch you have with rails running front to back. The only adapter currently available is the Demco 5th Wheel Rail Adapter for 8 foot bed # DM6206 of the 6-1/2 foot bed adapter # DM6194. 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. My recommendation is to use the Curt A16 # C16520-16025 for a long bed truck or short...

  • Factory Prep Package Puck Adapter to Universal 5th Wheel Rail Compatible Hitch for Ford, Ram & Chevy
    The Curt Q25 5th Wheel Hitch # C16265 will work with an adapter for the puck systems. You simply need to recognize that some adapters will limit the towing capacity. 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...

  • 5th Wheel Towing with 2019 Silverado 3500 Short Bed with Factory Prep
    If your goal is a lightweight 5th wheel towing setup in your 2019 Silverado 3500 short bed with factory prep then the combination of the Andersen Ultimate # AM3200 and the Demco Rail Adapter # DM6194 will work as long as your specific trailer's design gives it enough turning clearance when used with the 9-inches of offset from the Andersen. The distance from the Andersen's ball to the cab must be 4-inches more than half the trailer's width. Also, your trailer's pin box must be the fixed...

  • Availability of GM Factory Puck System 5th Wheel Rail Adapter for 2019 Chevy 2500 HD
    Yes, the Demco 5th Wheel Rail Adapter, part # DM6194 is exactly what yo need for your 2019 Chevy Silverado 2500. It's designed for Chevy/GMC trucks with OEM 5th Wheel Towing Prep Package with the 6-1/2' beds. Since you're using a slider, I assume you have a short bed, but if you have a long bed, you would instead need to use adapter # DM6206, and just make sure to keep the slider mechanism locked, since you won't need the extra turning clearance. The adapter simply drops into the four...

  • What is Needed to Install Demco Hijacker Autoslide in 2018 Chevy Silverado 2500 With Puck System?
     A Demco Hijacker autoslide fifth wheel hitch would be a great option for your 2018 Chevy Silverado 2500 and you would need the Demco 5th Wheel Rail Adapter # DM6194 to mount it in your truck bed with the factory puck system (I assume you have a short bed though if you did happen to have a long bed you would need Rail Adapter # DM6206). The Demco Hijacker has a capacity of either 18,000 lbs # DM8550034 or 21,000 lbs # DM8550035; this hitch slides automatically so you no longer have to be...

  • Can a PullRite SuperGlide 2900 5th Wheel Hitch Use the Demco 5th Wheel Rail Adapter # DM6914
    The PullRite SuperGlide model 2900 5th Wheel Hitch is designed to mount to industry standard (ISR) above bed rails.

  • Can PullRite SuperGlide 3100 5th Wheel Hitch Be Used on 2019 GMC Sierra 2500 with Factory Pucks
    We do not currently carry PullRite products but based on my research your 3100 model SuperGlide uses very specific mounting rails (not industry-standard) that are only designed to fit truck beds that are less than 6 feet. With this in mind the hitch is not compatible with the Demco 5th Wheel Rail Adapter # DM6194, which drops into the factory pucks on your new GMC to provide industry-standard, above-bed base rails. From the information I was able to find it doesn't look like the hitch...

  • Demco Hijacker Autoslide 5th Wheel Hitch ofr 2019 Ram with OEM Tow/Prep Package
    The # DM6107 Replacement Head and Base Assembly is missing the necessary side plates needed to attach to the # DM6099 OEM puck adapters. The complete hitch is part # DM8550035. You'd also need the # DM6099 or the # DM6194 adapter that will allow the hitch to attach to the in-bed puck system. If you don't already have the 7-way trailer connector in your truck bed, you can install one using part # DM8555002. I've linked you to install/product demonstration videos as well as installation...

  • 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.

If you don't have a slider base on your 20K Reese hitch, you will also want the Reese Square Tube Slider for 5th Wheel Trailer Hitch - 10" Travel # RP30048 unless your trailer has a Revolution or Sidewinder Pin Box to allow you enough turning clearance.

    The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package # DM6194 is what you will want to use if your truck has a short bed. It provides standard base rails in place of the pucks on your 2018 Chevrolet Silverado 3500 enabling you to still use your Reese 16K 5th Wheel Hitch. Keep in mind that you will want a sliding hitch for trailer-to-cab clearance when making sharp turns. If you still wanted to use your 16K Reese Titan head you could simply replace the stationary...

The adapter will mount directly to the factory pucks to provide you with above-bed, industry standard base rails with which the Demco Recon is compatible.

    There is an adapter that will work for your 2018 Chevy Silverado 3500 6-1/2 foot bed with factory pucks, the Demco 5th Wheel Rail Adapter for Chevy/GMC # DM6194. This will fit your PullRite Slider if it is an ISR Series that mounts to industry standard rails. I would love to give you a few different recommendations, but the Demco rails are the only option that fit into your '18 Silverado's puck system.

  • Comparing Curt 16023 and Demco 6194 Fifth Wheel Rail Adapters
    Each of the fifth wheel rail adapters you mentioned, the Demco # DM6194 and Curt # C16023 will offer you complete security for the hitches that fit on them. The Demco works by turning the locking plate with the thumb screw, which rotates the feet of the adapter locking it into place. The biggest difference between these two adapters is going to be the hitches they fit, which is generally the deciding factor in the adapter they have. The Demco adapter can accommodate any fifth-wheel hitch...
