Male 1: Today on this 2015 Ford F-350, we'll be having a look at and showing you how to install the Demco under bed rail and installation kit for Demco Hijacker fifth wheel and gooseneck trailer hitches, part number DM8551000. Here's what a Demco under bed system looks like installed. These under bed rails allow us to have all of the mounting solutions for our fifth wheel and gooseneck trailers underneath the bed of our truck. This will allow us to maintain full access to our truck bed and not lose any of the valuable space in it. One of the great features about the Demco under bed system is how easy it is to remove our fifth wheel to gain full truck bed access. So I'll show you how to do that now.We'll pull our clips, pull our pins out, move our handles to the unlocked position.
We'll do this on both sides. Now with an extra set of hands we can grab the slider, pull it out. Now, you'll see once our fifth wheels out of our truck bed, we have complete access to our entire bed of our truck. There is nothing that sticks up above it at all since it's all underneath. It does come with these plugs that you can install in the holes that you drilled in your bed to help keep dirt and debris out of the rails.These under bed rails will allow you to tow a fifth wheel trailer or a gooseneck trailer with the right adapter.
Comparing these two other fifth wheel or gooseneck options, what's really nice about this is being completely under the bed yet there's nothing that sticks up. It does provide a very clean look in your truck when you aren't towing your trailer, and you want to have full bed access. Now that we've gone over some features, we'll show you how to get them installed.To begin our install, we've measured according to the instructions to find the four locations that we need to drill our pilot holes in our bed. When taking these measurements, it's critical that we take the initial measurement from the end of the bed and not the end of our tailgate. If you have a plastic drop-in bed liner, you want to make sure you move it before you make your initial pilot holes.
You can always reinstall it before you put the rails back in and drill up from underneath the bed to enlarge the plastic bed liner if you want to. So we'll have a pilot hole near where the factory dimple is for the factory under bed puck system. So make sure we don't drill into that temple, but we drill where you measured.Now, with our pilot holes made at all four corners, we can now enlarge it to the appropriate size using a hole saw. We'll continue doing the same process for all four holes. Now to help prevent rust on our truck, we're going to take some clear coat and go along the inside edge.
If you have a spray in bed liner, you can just use flat black spray paint as well because that will match your bed liner.Now, we find ourselves in our wheel well. We need to insert our rail over the frame underneath the bed. We'll start with our rear rail first. Make sure the holes are facing up. We'll slide this in position right here. We go all the way across, and then we'll start to slide it back. We'll slide this back over the rear set of holes. We have lined up pretty good on the driver's side, but we need to get it further back on the passenger side. So we may need to use a hammer to tap it into place.Now, we can do our front rail. We'll insert it in the same manner. Now, we'll slide it back and show what's underneath or holes. We've already went ahead and took our fifth wheel or slider, we're using a slider in this case, dropped it in place into our bed, down in our rails, and secured to our rails. We have insured where the legs of our slider go through the bed of the truck into rails that all four are centered into our hole in the bed of our truck.Now, we'll bolt our frame brackets to our rails. To do that, we'll use a half inch bolt with lock washer and a flat Washer. Now for the back hole on our frame bracket on the driver's side, we'll insert a half-inch diameter bolt through that hole into the frame. It will be capped on the inside of the frame with a flat washer and a lock nut. Both the front and the rear hole on the passenger side bracket are the exact same way as this. For our center hole here, we'll take a three-quarter inch diameter bolt, we'll go through that and into the frame. On the inside, we'll cap it with a nut. Now, we'll take our pull wire, we'll go through our forward attachment hole. It'll come about our frame, and we can just pull it around back towards us like this. And we'll thread on our knurled bolt, and we can pull that through the frame. We'll move the pull wire, and we're thread on our flange nut.Now, we can go repeat the same process for the passenger side. The only difference being we won't have a knurled bolt on the front on the passenger side. We'll have a standard bolt like this with a washer on the inside and the nylon lock nut.Now we can start to tighten down our hardware that secures our frame bracket to the frame. Now, we'll do the other ones. Now that we have our frame brackets tightened to the frame on the truck, we'll now tighten the rails to our frame bracket. Now, we'll torque all of our hardware to the amount specified in the instructions.And that completes our look at and showing you how to install the Demco under bed rail and installation kit for Demco Hijacker fifth wheel and gooseneck trailer hitches, part number DM8551000 on this 2015 Ford F-350.
