The new lower base for the Demco hitch arrived on Tuesday via Freight it was a great interaction the driver I actually knew from a previous delivery, me and a friend were able to lift the old one out of the bed of my truck and install the new one today and all I have to say is...

PERFECT FIT!

It appears that Demco has already redesigned the lower base compared to my original one to prevent this problem from happening again. I was actually kind of shocked to see that upgrade and change.


I cannot say enough good words about you with E-Trailer and Demco working with me to get this problem solvedm Yes it took a little bit of work, ultimately this time we got it. I cannot thank you guys enough.

My friend and I will be finalizing the installation and getting it locked down to the bed with a few custom spacers for the lower rails this weekend.

Here are a few pictures of the installation resuming. If I remember , when I finally pick up my new camper, I'll send some pictures along too. Have to give credit where credit is due . Not sure of you have a customer wall at HQ. I know we had one in my old shop.

Anyway.. thank you again .

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

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 Etailer.com, 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 Ram2500

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.

See what our Experts say about this Demco 5th Wheel Hitch Rails

  • 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...

  • Comparing Demco Hijacker and Pullrite Superglide Fifth Wheel Hitch for 2017 Ram 2500
    The things that the 18K Demco Hijacker # DM8550034 and the 18K SuperGlide have in common are that they both offer 14" of travel, they are both automatic sliding 5th wheel hitches, have 2-point pivoting hitch heads, are compatible with industry standard base rails, and they are both rated to tow up to an 18K trailer. Both 5th wheel hitches come with a 5-year limited warranty as well. Although they both have the single-jaw system to lock the king pin into place, the SuperGlide hugs it against...

  • Fifth Wheel Hitch for a Rotating Kingpin on a Grand Designs Reflection 150 Series Trailer
    Part of your Grand Design Reflections 150's best features is the 90 degree pivoting pin box, and it would be a shame to not use it. You're right in that you don't need to have a sliding hitch given its design. However, you'll want to verify the clearance. I've included a link to our Sidewinder FAQ so you can get a similar idea of its features. Most importantly, in this article is how to calculate the clearance to verify if you need a hitch with offset to make the most of your pivoting...

  • Recommended Sliding 5th Wheel Hitch for Use on a 2017 Ram 2500
    According to the online version of the owner's manual for your 2017 Ram 2500 it states that the towing weight limits for a 5th wheel trailer are 25,000 lbs Trailer Weight and 5,000 lbs Tongue Weight. You will be able to safely pull your trailer with the 2500 model. The best option that we have when it comes to a sliding 5th wheel hitch is to use the Hijacker Autosliding 5th wheel hitch. The Demco Hijacker that I recommend is the 18K # DM8550034 along with the base rails # DM8552025-71...

  • Will the 5th Wheel Mounting Brackets on a 2020 Ram 2500 6.4 Hemi Mount on a 2014 Ram 2500 Diesel?
    It is possible that your industry standard rail system in your 2020 Ram 2500 may fit in your 2014 Ram 2500 Diesel but without knowing which brand or part number you have I can not say for certain. You will want to use all new hardware if you are able to transfer the kit over.

  • Best 5th Wheel Hitch Option for 2019 Ram 2500 Mega Cab With 6-1/2 Foot Short Bed
    With clearance being the biggest issue for you, there is one option I highly recommend for a 5th wheel hitch that fits your 2019 Ram 2500 with a 6-1/2 foot bed, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch with Slider # DM8550034. The Hijacker gives you more clearance than any other sliding hitch because of its 14 inches of front-to-back travel; other hitches have between 10 inches and 12 inches of travel. That will give you the most possible clearance for your 2019 Ram, and you...

  • 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...

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.

  • 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 5th Wheel Hitch for 2019 Ram 2500 w/ a Short Bed
    Due to the fact that the truck has the shorter bed, you'll want to go with a sliding fifth wheel hitch to provide enough clearance between the truck cab and the front of your fifth wheel. I recommend the Curt Q20 fifth wheel hitch, part # C16541 as well as the # RP50054-58 installation kit. The Q20 features a fully articulating hitch head and a two piece jaw mechanism that holds the king pin very tightly, which provides good ride quality. The slider mechanism will give you 12" of travel. For...

  • Demco Autoslide 5th Wheel Hitch and Base Rails That Fit 2019 Ram 2500
    I can get the correct Demco Autoslide 5th wheel hitch and base rails for your 2019 Ram 2500, and you are right that if you do not have any puck holes, you do not have the 5th wheel prep package. Since you have a lighter 5th wheel trailer of 16,000 lbs you do NOT need to get the 21,000 lb capacity # DM8550035. It won't provide you with any extra benefit and you would be paying extra for capacity you don't need, so the best option is to go with the 18,000 lb capacity Autoslide and save...

  • 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...

  • Is Trailair Air Ride Pin Box Compatible with Demco Hijacker Autoslide Hitch
    Trailair Air Ride 5th Wheel Pin Box # LC158778 is fully compatible with Demco Hijacker hitches such as the 18K # DM8550034 and 21K # DM8550035 which fit short beds fitted with standard above-bed base rails like Demco kit # DM8552025-71. You'll also want to use the Demco Capture Plates for Trailair Pin boxes # DM6171. Pin box part # LC158778 is a correct fit to replace a Lippert 1621HD 5th wheel pin box. This direct replacement will bolt right up in place of the 1621HD and give a smoother...

These are above-bed, industry-standard rails with which the Anderson Ultimate is compatible.

  • Best Fifth Wheel Hitch Recommendation for 2019 Ram 2500 Short Bed
    Hey Jake, so I know there's a lot of hitch options for fifth wheel towing and in general you are correct that cost and quality go hand in hand but to answer your question about what you really need versus what's available let's start with the fact that since you have a short bed truck you do need a slider hitch to provide tight turning clearance so you don't hit the cab of your truck on the nose of your trailer. The Demco Hijacker part # DM8550034 that you referenced is a really great...

    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.

    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.

It certainly looks like your base rails are industry-standard since your measurement taken at the outside edges of the holes is 29-3/4-inches.

  • Best Quality Sliding 5th Wheel Hitches for 2018 Ram 2500 Short Bed
    If your Ram 2500 with 6-1/2-foot bed has the factory 5th wheel prep (with mounting pucks in the bed) then I strongly recommend going with Demco's 18K Hijacker Autoslide # DM8550034 and the matching installation kit # DM6099. Not only does the Demco have 14-inches of slider travel (more than most slider hitches) it slides automatically when you make a turn. No more getting out of the truck (in the rain, of course) to release a manual slider. This USA-made Demco is shown in the linked video....

    If it were me I would use the Demco HiJacker 5th wheel hitch # DM8550034 which has 14 inches of travel and slides automatically like you said. Or you can use the 13K Demco hitch, # DM8550040, which has 22-1/2 inches of travel but is limited to 13,000 pounds gross trailer weight. According to Northwood the max gross trailer weight of the Fox Mountain 5th wheel is 13,500 pounds so provided you kept it below 13,000 pounds hitch # DM8550040 is a great option.

    If all you need is the capacity of the 18 Demco Hijacker part # DM8550034 that's what would be your best option. It's about 30 lbs lighter than the 21k version part # DM8550035. Unless you really like the diamond plate that is on this hitch. For fifth wheel rails you would then want the custom install kit part # DM8552025-71 that will minimize drilling and install time when compared to a universal kit.

    While it may be possible for you to tow a fifth wheel hitch with your 2018 Ram 2500 that has the RamBox, there is a compromise you will need to make as there will not be an underbed mount which you will be able to use. There is a great option for an easy to remove fifth wheel hitch, the Demco Recon # DM8550043, which comes in two pieces and weighs a total of just 125 lbs, making it the easiest fifth hitch to remove for truck bed access. It has a 21,000 lb towing capacity, a wraparound...
