Video Transcript for Comprehensive Review: Demco UMS Series Gooseneck Trailer Hitch for UMS Series Base Rails

Today we're going to take a look at the Demco Hijacker UMS series Gooseneck Trailer Hitch for Fifth Wheel Rails. It has a 25,000 pound weight capacity. Now this part will allow you to mount this gooseneck trailer hitch in your Demco Hijacker UMS series fifth wheel base rail, so that you can pull a gooseneck trailer. It will also work with standard above-bed base rails from other manufacturers like BMW, Curt, Draw-Tite, Hidden-Hitch, Husky, Reese and Valley that have the standard above-bed base rails. Basically easily installs and removes from the truck bed. It attaches with the pins and clips. It is constructed of a sturdy steel, and it does resist corrosion because it has a nice black powder coat finish on it.

It is made in the USA. You can see your gooseneck ball right here, and the holes for the safety chains to hook to. The ball diameter is 2-5/16", and again the gross towing weight capacity on this is 25,000 pounds. Just to show you how this would work, is you just pull these pins out, pull the clip off, then pull the pin out and you'll see your levers right here. You just rotate those out 90 degrees, and when you do that these tabs will rotate and that'll allow you and you do it on that side also, it'll allow you to lift it off of the base rails. When you go to install it, same way, you just open these up 90 degrees, the tabs will move, drop it into your base rails, once they're dropped in, just rotate these back, and then to lock them into place just drop your pin and clip through just like that, and that'll keep that handle from opening up and it locks it into your fifth wheel base rail and gives you the gooseneck ball to tow. That should do it for the review on the Demco Hijacker UMS series Gooseneck Trailer Hitch for Fifth Wheel Rails, with a 25,000 pound weight capacity..

  • What Are Mounting Puck Dimensions of Demco Hijacker UMS Series Gooseneck Trailer Hitch
    I appreciate you getting me the picture of your dimensions but it's not totally clear exactly what you have dimensionall. Instead check out the picture I attached that shows the dimensions of the mounts on the Demco # DM5988 that you referenced. What is the year/make/model of the truck? It looks like a factory rail kit from Ford, GM, or Dodge but I'd need to know what you have to be sure.

  • Will the Demco UMS Series Gooseneck Hitch Fit a 2015 Silverado 2500 Short-Bed?
    As long as the rails you currently have installed on your 2015 Silverado 2500 short bed are the UMS style rails, like the Demco # DM8551010, you can definitely use the Demco Hijacker UMS Series Gooseneck Trailer Hitch # DM5988. If you have another brand of auto slider and or rails, however, I cannot guaranty the fit.

  • Recommended Gooseneck Hitch Plate for 5th Wheel Rails
    It looks like the 18k Demco 6077 5th Wheel Hitch mounts on industry standard 5th wheel rails. To install a gooseneck ball on these rails, I recommend the Demco Premier Series Gooseneck Trailer Hitch item # DM5996. This plate will give you a 25,000 lbs capacity 2-5/16" gooseneck ball. I have linked a review video below. Some of the Demco hitches use a mounting pattern that is similar to the factory puck systems that come in newer trucks. If your 2005 F-250 has holes in the bed for your...

  • Dimensions of Mounting Pins for Demco Hijacker UMS Series Gooseneck Trailer Hitch
    I was able to go out to the warehouse and measure the center to center mounting posts for you on the # DM5988. I found that the center to center on the pin on the connecting same side of the bracket is 13-1/2 inches. The distance from the c2c of the opposite side bracket is 29-3/4 inches. I have included a diagram for you to better see. The # DM5988 will only fit the UMS series under bed rails. If you instead have a set of industry standard above the bed fifth wheel rails you will...

  • Best 5TH Wheel Trailer Hitch For a Short Bed 2024 Ford F-350 Super Duty Without Factory Hitch Prep
    I feel the Demco Autoslide 5th Wheel Trailer Hitch # DM8550037 is going to be the best option for any short bed truck like your 2024 Ford F-350. This hitch will automatically move back up to 14" as you turn to ensure you have enough cab clearance and do not have to manually move the hitch multiple times. The hitch will mount using the Demco Underbed Mouning System # DM32GV so you will not have above bed rails which interfere with sliding things in and out of your bed. Should you ever...

  • Comparing B&W Companion VS Demco Hijacker Autoslide 5TH Wheel Hitches For 2017 Ford F-250 6-1/2' Bed
    I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550022 for your 2017 Ford F-250 with the 6-1/2' Bed. With having the Autoslide you will be able to maneuver your trailer in tighter spaces by being able to make a jackknife turn. Since it does not require you to unlock the hitch like many manual sliders to achieve this you will be able to make quicker turns in tight parking lots while on your trips. The Underbed Rail and Installation Kit # DM8551009 will allow you to...

  • Will The Adapter Plate DM6333 Work With The Demco Under Bed Rails DM8551004
    No, the Adapter Plate # DM6333 will not work with the Demco # DM8551004 underbed rails. The adapter plate is made to work only with the Chevy of GMC factory puck systems. The Underbed Rails # DM8551004 will only work with Demco Underbed Mount Series (UMS) 5th-wheel and gooseneck trailer hitches, like the Demco Autoslide 5th Wheel Trailer Hitch # DM8550022. The only adapter available for the Demco Underbed Rails # DM8551004 is the Demco UMS Series Gooseneck Trailer Hitch for UMS Series...

  • Is Demco DR37FR Under Bed Rail System Compatible Wtih B&W or Curt 5th Wheel Hitches
    The Demco # DR37FR Underbed Rail Kit you'd looked at is only compatible with the Demco Hijacker Underbed Mount Series (UMS) 5th-wheel and gooseneck trailer hitches such as: • Hijacker UMS Gooseneck Hitch # DM5988 • Hijacker UMS 20K Double Pivot 5th Wheel Hitch # DM8550032 • Hijacker 18K Autoslide # DM8550022 • Hijacker 21K Autoslide # DM8550037 For an underbed mount for a sliding B&W Companion hitch like # BWRVK3400-5W, you'd need their Turnover Ball Gooseneck hitch like # BWGNRK1020-5W I've...

  • Can I Adapt Demco Hijacker To Tow Gooseneck Trailer
    There is not a way to switch out the top of the Demco Hijacker with a gooseneck ball. However, if your Demco Hijacker fits under bed UMS Demco rails like the Demco Hijacker part # DM8550032 you can use the Demco Hijacker UMS Series Gooseneck Trailer Hitch for UMS Series Base Rails part # DM5988. The adapter will attach to the UMS underbed rails and give you a goose neck ball in the truck. You will have to remove the Hijacker to do this. If the truck already has industry standard 5th wheel...

  • Recommended 5TH Wheel Hitch System For a 2021 GMC Sierra 2500 Short Bed Without Factory Puck/Prep
    I have another recommendation for you as I have heard a lot of complaints about the Curt CrossWing # C32DR and the amount of noise it makes. I also do not feel the offset is going to be enough to prevent damage between your truck and trailer when maneuvering. I recommend going with the Demco Autoslide 5th Wheel Trailer Hitch # DM8550022 on your 2021 GMC Sierra 2500. This uses the Demco UMS System # DR37FR which places the rails under your bed so you can maintain the clean bed when you...

  • Demco Highjacker Mounting System For a 2021 Chevrolet Silverado With 6-3/4' Bed Without OEM Puck Pkg
    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550037 requires multiple mounting points on the frame of your 2021 Chevrolet Silverado 2500. Therefore you will not be able to use the Curt X5 5th Wheel Base Rails Adapter # 16310. No autoslide 5th wheel hitches can be used with a single point mount such as a B&W turnover ball or Curt double lock gooseneck. The Underbed Rail and Installation Kit for Demco Hijacker # DR37FR will allow you to keep a clean bed when you do not have...

    In order to easily tow both 5th wheel and gooseneck trailers and to leave the bed free when the hitches are removed, you'll want to use a Demco Hijacker Autoslide that uses their UMS under bed rails. For a 21K capacity Hijacker Autoslide hitch, you'll want so use part # DM8550037 with the # DM8551000 rail kit. Once the 5th wheel hitch is removed, you would use the # DM5988 gooseneck hitch which is compatible with the UMS rails. This option provides a lot of convenience, as the hitch...

    With your 2020 Chevy Silverado 2500 only having a 6-3/4 ft bed with out the OEM prep package it's recommended to use a slider to provide enough clearance between the nose of the camper and the cab of the truck. I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 21,000 lbs Item # DM8550037.

  • 5TH Wheel Trailer Hitch For Lippert Turning Point On 2012 Chevrolet Silverado 1500 5-1/2' Bed

This is due to the single attachment point of this particular style hitch. If you wish to keep the same clean bed style as the B&W with your short bed(5-1/2') 2012 Chevrolet Silverado 1500 you will need the Underbed Rail and Installation Kit # DM8551008. This will allow you to use their Demco Hijacker UMS Series Gooseneck...

  • Do Demco Fifth Wheel Rails Require Demco Fifth Wheel to Gooseneck Adapter
    Demco uses/used a few different styles of fifth wheel rails over the years so the key will be determining what rails you have now so that we can pick out the correct adapter you'd need. The part # DM5988 you referenced is for the UMS style rails which are an underbed rail that looks like part # DM8551010. If you have what looks like standard fifth wheel rails that sit on top of the truck bed and are spaced 22 inches apart like part # RP30035 then you can use more of a standard gooseneck...
