Just received wont be installed till Monday, but the customer service when ordering and the shipping was awesome. Will update when installed and I pull my new camper home (50miles) with pics



Just as I had hoped, great

2017 Ram 2500

Product fit exactly as advertised and the installation video on etrailer's website was a great help in the installation since the installation directions that came with the kit was not very informative. I hope etrailer continues to provide installation videos for products they sell and I will definitely but from them again.

Thanks etrailer.


The Demco slider hitch I purchased with you bed kit is truly a phenomenal piece of equipment. I’ve had many questions about my hitch to which I’d recommend to any and everyone. This is my first fifth wheel and my first experience with pulling a fifth wheel. It’s truly amazing how it operates

2015 Ram 2500

Haven't used this yet, but believe it will be terrific for lifting my Demo 5th wheel hitch to move to another truck. Purchased my Demo hitch also from, they are fast shipping, let you know exactly what you need for your particular vehicle. I would recommend them highly for any of your camper & auto and RVing needs!


I recently called Diana at etrailer and requested a product for a brand new dodge ram that know one else could locate. Without hesitation she new exactly what I needed and told me so right away without putting me on hold or anything, great job Diana and great products you guys have. Keep up the good work

2018 Ram 2500

The product was in good order. The install is somewhat difficult. The backside driver and front side passenger is easy to install. The drivers front and rear passenger is the most difficult. It would be helpful if the template was sent with the package so that you could layout the bed and drill everything from the top. Because you can't get to the front drivers side from under the truck. It took me 3 hours to install this product. One last comment is that there are 2 bags of nuts, bolts and bushing but you have to figure out what ones to use. If you know the make and model of the truck why can't the correct bolts and all of the accessories be put in the box.

2018 Ram 2500

This is my second order for my second truck. I couldn't be happier with the pricing, service, delivery time, and courteous people.

Great, very happy.

  • Parts Needed To Install Demco RV Fifth Wheel On Ram 2500 With Standard After Market Rails
    # DM8550035 will fit all industry-standard rails, including those from B&W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley. All you have to do is bolt on the side plates and attach the head to the hitch base. If you have any of these industry standard rails then the hitch will fit your truck. The side plates have 2 functions. They contain the feet that fit into your above-bed rails, and they allow you to raise or lower the hitch head to better match your pin box height....

  • Demco Slider For 2018 Ram 2500 Short Bed
    I do have an option for you but the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider part # DM8550022 fits a Demco UMS underbed rail kit which is not available for your 2018 Ram 2500 short bed. If your truck does not have the OEM prep puck package, I recommend the same Demco autoslide hitch part # DM8550034 (which is the same hitch but fits into the bed differently) with fifth wheel rails part # DM8552025-71. This will give you the Demco Auto Slide hitch that will fit into fifth...

  • Best Slider Fifth Wheel Hitch and Rail Kit Recommendation for a 2014 Ram 2500
    Yes, the two part numbers you mentioned would fit your 2014 Ram 2500 short bed without the hitch prep package and would work very well for you. The rail kit part # DM8552025-71 is a custom fit kit designed specifically for your truck to minimize drilling and install time. The Hijacker # DM8550034 will automatically slide around tight corners which will greatly reduce the hassle of towing with a short bed truck. Normally you have to get out and manually operate the slider every time you...

  • Can 2019 Ram 2500 with RamBoxes Tow Fifth Wheel Trailer
    There is a way to tow a trailer with your 2019 Ram 2500 short bed that has the RamBox cargo system but you will have to install a Sidewinder pin box on the trailer. Standard pin boxes when turning would contact the bedrails and damage them but with the Sidewinder the pivot point is moved up above the bed rails which prevents contact. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker...

  • Could Demco Fifth Wheel Rail Kit be used with Pullrite Fifth Wheel Hitch
    If the Pullrite Superglide you have was designed to fit the industry standard rails (it will have ISR listed in model name), then yes the Demco rail kit part # DM8552025-71 would work. If not, then the only rail kits that will work are from Pullrite.

  • Which 5th Wheel Base Rails are Compatible with Demco DM8552025 Frame Brackets for 2017 Ram 2500
    The Demco # DM8550043 Recon 5th wheel hitch is compatible with industry standard bed rails such as those provided with the Demco # DM8552025-71 bracket/rail kit. The kit combines the # DM8552025 brackets along with the # DM6071 industry standard rails. The hitch fits on industry standard rails from Reese, Husky, Valley, B&W, Demco ISR and Curt, among others, but if you use Demco frame brackets, you'll want to use bed rails from the same manufacturer. The brackets and rails aren't capacity...

  • Demco Hijacker Fifth Wheel Hitch or Pullrite SuperGlide for 2019 Ram 2500
    When comparing the Demco Hijacker and Pullrite SuperGlide for your 2019 Ram 2500, I highly recommend going with the Demco Hijacker for a number of reasons The first reason is the superior jaw system of the Hijacker. As you can see by the accompanying photo, this hitch has a single-piece jaw that wraps completely around the king pin, and has an enhanced connection via a 3/4" solid steel bar that locks into place once the jaw is closed. This reinforced jaw system is what will give you a...

  • Are Rails and Brackets Needed to Use the Demco Hijacker Autoslide on a 2014 Ram 2500
    If you don't have the OEM puck system or industry standard base rails on your 2014 Ram 2500 then you will need the Demco Hijacker Premier Series Above-Bed Base Rails and Bracket Kit # DM8552025-71 to utilize the Demco Hijacker Autoslide # DM8550034. If you do have the OEM puck system then you will need the Rail Adapter # DM6099 for the Hijacker to mount to. Please note that the Hijacker should not be used if you have the RamBox on your pickup. You will also need 5th Wheel Wiring Harness...

  • Do Fifth Wheel Rails Have A Weight Rating
    Fifth Wheel Rails like Demco Hijacker Premier Series rails part # DM8552025-71 are not rated. What is rated for weight capacity is the hitch that goes on the rails such as the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035 which is rated for 21,000 lbs. The only way to install the fifth wheel rails is to remove the gooseneck hitch you have installed in your truck because they install in the same spots on the frame.

  • 5th Wheel Hitch Rails And 7 Way Connector For 2019 Ram 2500 w/out Puck System
    It is possible that your old rail system may fit your new 2019 Ram 2500 without prep package, but without knowing the part number or previous vehicle that you had, it is difficult to say for sure. I went ahead and gathered some information on 5th wheel rail kits that are a fit for your 2019 Ram without prep package and you can see if your current rail system happens to match one of the part numbers.

    The Demco Hijacker Premier Series brackets, part # DM8552016, are confirmed to fit models of the Ram up to 2012 but not your 2016. Which kit fits your truck depends on the size of your Ram: Part # DM8552030-71 for the 1500 Part # DM8552025-71 for the 2500 Part # DM8552026-71 for the 3500

  • Can Demco Hijacker Autoslide Be Installed on 2016 Ram 2500 w/o Removing Existing B&W Turnover Ball
    I have looked over the installation instructions and videos for both the # BWGNRK1384 B&W Turnover Ball and the # DM8552025-71 Demco install kit for the # DM8550034 18K or # DM8550035 21K Demco Hikacker Autoslide. From everything I can see, the Turnover ball won't interfere with installing the Autoslide 5th wheel hitch, and the folks at Demco didn't see a problem with it either so there's no reason to believe it wouldn't work. I'll link to the two installation videos for the Turnover...

  • Removing Brake Line Clips for Installation of Demco Above-Bed Base Rails
    Yes when installing the Demco Above-Bed Base Rails and Custom Installation Kit, # DM8552025-71, you should be able to reinstall the brake lines as they where from the factory, careful to not brake or damage the clip. For installation of the brackets, the clips will/may need to be removed to accommodate installation of some hardware and for having access of tools/sockets to tighten nuts. Once the new brackets are installed the brake lines/clips should be able to be reset as per the factory.

  • Recommendation for a 5th Wheel Hitch to Fit a 2014 Ram 2500 With 6 Ft. Bed
    I found a couple 5th wheel hitches that will work well with your 2014 Ram 2500 with 6 ft. bed. The first hitch I like is the Demco Hijacker Autoslide 5th Wheel Hitch, # DM8550034, and the Demco Above-Bed Base Rails, # DM8552025-71. This Demco hitch has a weight capacity of 18K lbs and a pivoting head to help reduce chucking. The best feature of the Demco hitch is the Autoslide function. This feature will automatically engage the hitch's slider without exiting the cab of your truck. The...

  • Parts Needed to Install a Demco Hijacker Auto Slide Fifth Wheel Hitch in a 2016 Ram 2500 Short Bed
    We have just what you need to install a Demco Hijacker Auto Slide fifth wheel hitch # DM8550034 in the bed of your 2016 Ram 2600 short bed. You will need to install the rail kit part # DM8552025-71 in the bed of your truck to give the hitch something to attach to. This is a custom install kit so that means the install time will be about half that of a universal kit and it will minimize frame drilling. Your spray-in bed liner would not be an issue at all.

  • Automatic Sliding Fifth Wheel Hitch Recommendation for 2016 Ram 2500 without Factory Rail Kit
    For your 2016 Ram 2500 short bed without the factory rail kit the hitch setup you would want is the Demco Hijacker Auto Slider. Part # DM8550034 for an 18k hitch or part # DM8550035 for the 21k version of the hitch. For a rail kit you then would want the custom install kit part # DM8552025-71 which is custom fit for your truck and would minimize drilling and install time. I attached review videos for the hitches for you to check out as well.

  • Auto Slide 5th Wheel Hitch and In-Bed Trailer Connector Recommended for 2020 Ram 2500
    I'd recommend the 18K capacity Demco Hijacker Auto Slide 5th wheel hitch, part # DM8550034 and the # DM8552025-71 bracket/rail kit. Just as the name states, the Hijacker Auto Slide hitch head will slide rearward during sharper turns to provide the necessary clearance between the front of the fifth wheel and the rear of the truck cab. For the trailer wiring harness to mount in the truck bed, I'd recommend the Curt # C56000. If you use the provided links, you can see a demonstration video...

  • How to Determine Height Setting of Demco Hijacker Autoslide 5th Wheel Hitch on 2019 Ram 2500
    The first thing to know is that you'll need to have at least 5 inches to 6 inches of clearance between the top of your bed rails and the bottom of the trailer loft. You'll want to measure from the ground to the top of the bed rails on your 2019 Ram 2500 and then from the ground to the bottom of your trailer loft and the difference will be your clearance. Your Demco Hijacker 5th Wheel Hitch # DM8550034 (18,000 lbs) or # DM8550035 (21,000 lbs) have height settings of 15-1/4 inches, 16-1/2...

  • Will Andersen Ultimate Allow a 90 Degree Turn When Towing with a 2017 Ram 2500 6-1/2 Bed
    The Andersen Ultimate Connection # AM3200 has a 9" offset. I am not sure if it will allow you to make 90 degree turns with your 2017 Ram 2500 6-1/2' bed but this can simply be determined by measuring from the back of your cab to the middle of the space in-between your base rails (or the pucks). Once you know that simply add 9" for the offset and the subtract half of the width of your trailer. The formula looks likes this: (A + B) - C = Clearance A = Distance from center of fifth wheel...

  • Does the Demco Hijacker Autoslide 5th Wheel Hitch Only Fit Demco Base Rails
    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550035 referenced in your question is an excellent choice for your 2014 Ram 2500 with a 6-1/2 foot bed. As you mentioned, this 5th Wheel Hitch is compatible with the Demco Base Rail Kit # DM8552025-71, but it is also compatible with any industry standard, above-bed base rail kit. If you are not wanting to use the Demco Rails, I recommend looking at the Reese Quick-Install Custom Base Rails and Installation Kit # RP50054-58 or the...

  • Recommended Autosliding Hitch and 5th Wheel Rails for a 2023 Ram 2500
    Congrats on the new truck! To add a autoslider 5th wheel hitch you will first need to add a set of rails to your 2023 Ram 2500. There is no aftermarket way to add a puck system or below bed mounting method for an autoslider 5th wheel hitch. I recommend the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit item # DM8552025-71. This set of rails is industry standard which means it will work with most 5th wheel hitches on the market. The brackets are custom fit and install...

  • Weight Capacity Of Bed Rails Included with Demco DM8552025-71 5th Wheel Bracket/Rail Kit
    The # DM6071 rails provided with the Demco # DM8552025-71 bracket/rail kit will absolutely handle the 21K capacity of the Demco # DM8550043 Recon 5th wheel hitch you mentioned. The bracket/rail kit has a 25K capacity per the folks at Demco, so you'll have some capacity to spare. You'll want to keep in mind- for a short bed truck, unless your 5th wheel has the concaved-in front corners and the 5th wheel manufacturer specifically states that a sliding hitch isn't necessary, you might not...

  • Gooseneck or 5th Wheel Hitch Recommendation for 2016 Ram and Grand Design 5th Wheel Trailer
    I looked up the BDS lift kit and it is a suspension lift which is good because that means the truck bed and frame are still the same distance apart from each other so you can install a hitch in the bed. If towing a 5th wheel trailer you will want a 5th wheel hitch but given your situation I do have a recommendation that will work as long as the 5th wheel trailer has the tapered front end for short bed trucks and as long as it has a pin box that is compatible with a Reese Goose Box.
