Expert Answers about Demco

  • How To Check if Trailer Surge Brakes Are Working Properly On Tandem Axle Boat Trailer
  • Checking the brakes can be done in two ways. The easiest way is to raise one side of the trailer and spin the wheels while someone applies the surge brakes at the coupler. The better way would be to remove each of the wheels and brake drums and activate the brakes while making sure the wheel cylinders and brake assemblies are functioning properly. After this the first thing I would do is bleed the brakes using the trailers surge coupler to force the fluid from the brake lines and make...

  • Recommended Sliding 5th Wheel Hitch For Short Bed Truck With Rails Installed
  • The rails in your 2005 Ford F-250 with 6-3/4 foot bed are standard rails compatible with most hitches. Because you have a short bed, you will need a sliding hitch. There are a few options for you, but I'll give you a recommendation for an auto-slide and a manual sliding hitch. The reason you will need a sliding hitch is because the clearance between your truck and trailer is limited due to the short box, so you want to make sure you have the ability to turn in tight spaces without having...

  • Where Can VIN Be Found On Travel Trailer
  • The trailer A-Frame tongue is the first place to check. Look for a ID plate affixed to the frame near the coupler. If the ID plate isn't evident there, check the front storage compartment and look over any exposed frame members in that area. On some travel trailers, The ID plate is actually inside the trailer, inside a storage cabinet.

  • Compatibility of Demco Autoslide with 2018 Ram 2500 6.5 Foot Bed
  • The Demco 13K with a 22-1/2 inch slide # DM8550040 and # DM8550041, will not work for your application. It would cause issues with the tail gate. The confirmed fit for your truck is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - 18,000 lbs # DM8550034 or the 21K # DM8550035. Either will work well with the Rail adapter for Ram 5th Wheel Towing Prep Package # DM6099 or the Reese 5th Wheel Rail Adapter # RP30154. The weight of the hitch is 273 lbs for the 18K and...

  • 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...

  • Adapter Needed for 5th Wheel Hitch on a 2018 Chevy Silverado 3500 with the Factory Puck System
  • The Demco 5th Wheel Rail Adapter # DM6194 is an adapter rated for 21K that changes the factory puck system on a GMC or Chevy so that a 5th wheel hitch that installs on industry standard rails can be used for your towing setup. It will fit and work well with the puck system on your 2018 Chevy Silverado 3500 if it has a short bed.

  • Pullrite Superglide or Demco Hijacker Comparison
  • The advantage the Pullrite Superglide would have over the Reese hitch # RP30083 is that you would never have to get out of your truck to activate the slider. We don't sell Pullrite hitches, but that would be a huge selling point for me to pick it over the Titan. However, I do have an additional option for you to consider that we DO offer that does automatically slide like the Pullrite. I really like the Demco Hijack part # DM8550034. This hitch would work similarly to the Pullrite,...

  • Recommended 5th Wheel Hitch for 2018 Ford F-250 with 6-3/4 Foot Bed
  • Yes, the 2018 Ford F250 will work fine for the 5th wheel you mentioned. I recommend going with the factory rail kit to give you a clean bed when you are not towing. I also recommend the Demco Hijacker Autoslide 5th Wheel Hitch w/ Slider - Single Jaw - Ford Super Duty Prep Package - 18K # DM8550024 which will automatically slide to give you turning clearance for your short bed truck. This particular hitch it designed specifically for your truck. If you prefer a manual slider option,...

  • Best Fifth Wheel Hitch Recommendation for 2017 Ford F-250 Short Bed with Rail Kit
  • The hitch I would recommend for your 2017 Ford F-250 short bed with the factory rail kit is the Demco Auto Slider part # DM8550038. This hitch has a 21k capacity, but what really makes it nice is that it attaches directly to your rail kit and automatically slides as you make tight turns instead of forcing you to get out of your truck every time you need to slide the hitch. It's not super lightweight but can easily be broken down into smaller sections to make removing it easier. I attached...

Safety margin in towing capacity is always a sensible idea. In your truck that has the factory 5th wheel prep an 18K hitch like the Demco Hijacker Autoslide # DM8550034, or better yet their 21K # DM8550035, will provide the same automatic sliding feature and a full 14-inches of slider travel, the same as the PullRite 4400. Both...

  • What Brake Fluid Should be Used in Surge Brake Actuators

  • Locking Plate for Mor Ryde Pin Box to Make Trailer Demco Hijacker Autoslide Compatible
  • For the Demco Hijacker Autoslide to work properly with a Mor Ryde pin box, the Demco Hijacker Autoslide Locking Plate for MOR/ryde Pin Boxes # DM6025 is required. This plate will keep the pin box from moving independently of the hitch head that determines the correct pivot for turning clearance. I've attached the installation details to assist.

  • Troubleshooting Surge Brakes Locking up When in Reverse
  • With surge brakes, you have a brake actuator applying the needed pressure to the brakes but to be able to back up you will need to have a manual lockout or an electric lockout solenoid, like # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed up. You may also need a solenoid cover like the Titan # T4835800183, depending on what brake actuator you currently have. Typically surge brakes are found on boat trailers, and commonly the...

  • Recommendation for Installation of a Brake Mounting Flange on a Trailer Spindle and Axle
  • Welding a mounting flange, possible item # 4-35, is a very precise installation. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle can occur. Usually special jigs are used to install the flange. The jig will keep the flange square and concentric to the axle and...

  • Can Demco Glide Ride 5th Wheel Pin Box DM8250011 Be Used with Gooseneck Adapter

  • 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...

  • Installation of Demco Frame Brackets for Demco Hitch # DM8550022 on 2016 Ram 2500 6.5 Foot Bed
  • On your 2016 Ram 2500, there are a couple notes in the instructions: On drivers front bracket unclip wires/hoses from inside of frame to allow bracket to fit flush to frame. Front brackets are mounted to the inside of the frame and the rear brackets are mounted to the outside of the frame. On the front brackets make sure you insert the spacer block between the frame and the bracket on the front hole location of the Demco Custom Brackets # DM8553016. Unfortunately the installation...

  • How Long Does it Take to Install Demco HiJacker 5th Wheel Hitch in 2015 Ford F-350 w/Prep Package
  • Since your 2015 Ford F-350 has the factory 5th wheel prep package the only installation of a 5th wheel hitch that is a direct fit is placing it in the pucks and turning the locking handles. So for example if you were using Demco HiJacker # DM8550024 you would place the hitch in the 4 pucks, make sure it is seated, and turn the handles to lock the hitch down into place. You will likely want to place the hitch in the truck in parts because the whole thing is over 200 pounds. I have...

  • How to Reset Breakaway Cable of Atwood Surge Brake Actuator
  • If your emergency/breakaway brake cable has been pulled slightly that would be why the brakes aren't releasing like they are supposed to. You need to reset it so that the brakes will release like they should. To reset the breakaway cable on the Atwood Hydraulic Brake Actuator, item # 84132, you will need to feed the cable back through the opening in the top of the housing so the push rod can be properly released into the master cylinder. Once this is done, pressure from the master...

  • Is the Demco Base Rail Adapter # DM6140 Adjustable Vertically for Truck Bed Liners
  • The shaft portion of the Demco 5th Wheel Base Rails Adapter # DM6140 that you referenced is vertically adjustable so that you can match the height of the bed perfectly. This is helpful when the truck has a bed liner and the bed floor is slightly raised because of it. I attached a picture that shows how the adjustment is made.

  • Fifth Wheel Hitch and Tonneau Cover Recommendation for 2017 Ram 3500 with Short Bed
  • For your 2017 Ram 3500 6-1/2 Foot Bed without Factory Rail Kit you'll need a slider hitch to allow you to make tight turns without cab interference. My favorite slider hitches are the ones that automatically slide as you make tight turns as that saves you the hassle of getting out and activating the slider every time it's needed. For that I would recommend the Demco Hijacker part # DM8550037 and the install rail kit part # DM8551006. This is an underbed rail kit too which means when...

  • Recommendation on How To Easily Lift Demco Autoslider Into Bed of Truck
  • This is a great question. We actually addressed this with Demco and we came up with a solution. They started making the Demco 5th Wheel Lifting Bracket # DM6100 which can be used with an engine hoist, or winch, but we have also found a more mobile option in the MaxxTow Hydraulic Pickup Truck Crane for 2" Hitches - 1,000 lbs # MT70238. This allows you to easily load and unload a heavy hitch like the Demco Autoslider # DM8550034.

  • Automatic Slider Fifth Wheel Hitch Recommendation for 2018 GMC Sierra 3500 with Rail Kit

For that we have the Demco Hijacker Autoslide part # DM8550034 which has an 18k capacity and slides back 14 inches as you make tight turns. The adapter you'd need then is the # DM6194 which fits the rail kit of your truck and provides the rails for the hitch. The rail kit fits tight to the truck so you wouldn't have any movement/noise...

  • How to Fix Chucking and Jarring With 5th Wheel Hitch
  • What you were experience is what is known as chucking. This is not something unusual and it can be caused by your 5th wheel jaw(s) not being very snug around the king pin, and/or the head of your 5th wheel does not move or pivot very much. When you hit a bump in the road, there is just enough wiggle room for the king pin to move since the trailer is moving differently than the truck for those few seconds. Another possibility that you will want to check is the Tongue Weight. The Tongue Weight...
