How to Install the B and W Base Rails Kit on a 2020 Ford F-250 Super Duty


Ryan: Hey everybody, Ryan here at etrailer. Today on our 2020 Ford F250, we're going to be taking a look at and showing you how to install the B&W custom installation kit with base rails for a fifth wheel trailer hitch.Fifth wheel trailers are becoming more and more popular these days. We've got a lot more people kind of getting into camping and things of that nature. And for me, having a quality trailer hitch would be a top priority. That way you're going to have something reliable and you can count on to safely pull that trailer down the road. And that's all going to start with your base rails, and these are actually going to be the main connection point, which ties into your truck's frame.

So a very important component here and with a B&W setup, it's one you really can't go wrong. With. I'll say B&W is my favorite, and that's really due to the quality of craftsmanship. These things are very well-built, even down to the hardware, all the brackets, everything fits really well. It's just a really good working choice.One thing that's really nice about these base rails as well is that they're going to work with most of your standard fifth wheel trailer hitches.

Now, if you're in the market for one, one of my favorites is the B&W Patriot. And in fact, that's what our customer is eventually going to get. With that being said, it's a really reliable and easy to use hitch and should last a long time.Even though the rails do sit above our bed a little bit, they're relatively low profile. They don't really take up a ton of space. I feel like if you needed to throw something in the bed of your truck, whether it be lumber, a motorcycle or whatever you're trying to put back here, I really don't see it causing you too many issues, and I don't really see these getting too beat up, either, especially over time.

They have a really thick powder coat finish and it should keep them protected and looking good.Now, one big question we get asked is if you can still put a toolbox in the bed of your truck, and I'm going to give you a measurement from the front of the bed to the very edge of the rail, and I'll keep in mind, this measurement could vary a little bit, depending on your fifth wheel hitch, if it comes out a little bit further or what have you. But today on our short run, we go from the front to the very edge it's going to be right at 24 1/2". So at least that can give you a little bit of information to maybe help figure out if a toolbox can indeed be placed back here in conjunction with your hitch.Now, with this being a custom fit kit, the installation and actually getting everything in place really isn't too bad. The quality of B&W and them working around everything and using existing holes in your frame rail really does save you a ton of time. Even down to the little things with them marking the side-specific brackets and everything, that really does go a long way, so all those little details do add up.Another thing that B&W has thought of, which is nice, is the fact that they include some special tape.

Now, you may not think much of the tape, but it's actually pretty important, and that's because with our new Fords being aluminum and our other components being steel, whenever you mate those two different metals together, some corrosion and things like that can occur. When you apply this special tape in between those two surfaces, it's one less thing you're going to have to worry about. This is going to prevent any of that corrosion.But speaking of the installation, why don't we go ahead and put this on together now. To begin your installation, what you're going to want to do is lay out not only your rails, but your frame brackets as well and apply this included tape to the bottom of them. So I've already done that. Simply just laid on and trim it off. In the instructions, there's a diagram telling you exactly where you need to place this tape. The reason for it is since the truck bed is made from aluminum, this just gives an extra layer of protection in between that aluminum and our steel brackets.So now we can do this, hop up in the bed of the truck, and we're going to grab one of our rails and bring it up here with us, and we're going to do some measurements to figure out where we need to set this up. So the measurement's in the instructions and what you want to do is measure from the actual back of the truck, the very end of the bed. You don't want to measure from the tailgate, if that makes sense.So I've done that. I've brought it out and made a few marks along where we need to go here. Then what we can do is you want to take your rail and set it up on those marks. Then what you want to do is make sure that the rail is centered. So you can measure from the wheel well here to the very edge of the rail and do that on both sides and to make sure it's centered, you want that measurement to be the same on each end.So once our rail is in that correct position, we need to mark out our hole locations where our fasteners are going to secure this. For the rear rail, that I have a total of six. We're going to be using this one here. So what you can do is just put a little mark there in the center, the same thing right there. It'll be using these two in the center. We'll put your marks.Then on this sand, we're going to be using these very last two holes as well. So once we have them marked in the center, we can move our rail out of the way. That way we drill out some pilot holes.You want to use a small drill bit for your pilot holes and before you do any drilling, you definitely want to check underneath the truck to make sure no components are going to be directly underneath. That way we don't have to worry about damaging them. So I took a peek under there and we're all clear. So I'll just go and come back to our marks and draw them out.Now, we can do this, loosely install our frame brackets. That way we can verify the pilot holes we just drilled end up lining up with this. So pretty simple. These are side-specific. We're on the driver's side and that's indicated with this D. The passenger side is set up the same exact way, it just has a P on it. But we're going to be using these two holes here, and those are going to line up with these two holes into our frame rail.We're going to line that up, and then we're going to take these larger bolts, put on a flat washer, we could simply just push them through. It's not the bolts or kind of just keeping it in place. We can go underneath the truck and loosely secure them. So underneath the truck, you could see there's where one of our bolts is coming through and the other one's right up there. What we're going to do is just take a flat washer, slide it over the bolt, a split lock washer and a hex nut. We're just going to get a couple threads going here, just get it hand tight. Use that same hardware combination for that full there, and once I have that on, I'm simply going to repeat this exact same process over on the other side of our truck.Back in the bed of our truck, the hole that we need to make sure lines up is this one here, for this is outside and closest to the back of the truck. That's on each side of our truck as well. But what I'm going to do just to make sure it lines up is this use a thin piece of wire. You could use a coat hanger or something like that. I'm just going to push that down and then we can go back to our frame plate and make sure that this wire does indeed go through the hole there, verifying we're lined up correctly.So back on the side of her truck, here you can see the wire does indeed come down through the center of that opening and our frame plate. So I'll check the other side, verify that one's good as well.So now back up in the bed, what we can do is drill out each pilot hole to the size that's indicated in the instructions. Now, there is one thing I do want to mention. The hole here in the center, closest to the front of our truck, that's actually directly above a bad cross member that runs underneath. So when you drill that out, not only do you want to go through the first layer of the bed, but you also want to continue down and drill a hole through that cross member underneath. You want to get it straight as possible.Once you have that drilled out, we actually need to enlarge the hole here, just in the portion of our bed, and that's because it's going to receive a spacer and some little bit different hardware. So to enlarge that to the proper size, I'm just going to use a step it, and again, make sure you only really enlarge a hole just in the portion of our bed, not the cross member underneath.Now that we have all of our holes drilled out, I'm just going to grab my vacuum cleaner and clean up our mess here.Now, even though our bed is made from aluminum and we shouldn't have to worry about rust, what I'm going to do, though, is just grab a paint pen and put a layer over that exposed metal. Now we can go ahead and loosely secure our base rail. So hardware combination is a little bit all over the place here, but we'll go through it piece by piece. The first thing you're going to want to do is take this tube spacer, and here in the center where we enlarged that one hole, we're just going to want to drop that down in there. We're going to line it up with the hole in the cross member as best you can. Then once we have that there, we can take our base rail and set that into position.So right here underneath the bed rail, where the bed corregation goes, we're going to take one of these U-shaped spacer blocks on the side that contacts your bed. You want to put some more of that tape. So we'll kind of sneak that under there like so. Then we're going to take this long carriage bolt and just drop that down into position.For this one here, again we're going to take a U-shaped spacer, put that tape on it, get that under there. Then we're going to take one of these carriage bolts and drop that down through. Now, if you move over to the end right here, this hole, we're just going to take another carriage bolt and pop that through. For this side, we're going to take a hex bolt, a split lock washer, and drop that through. So with the other end of our base rail, this hardware combination's going to be the same, so I'll go ahead and drop that down through as well.Now we can work on securing our hardware. So we're over here in our wheel well, and if you remember, one of the bolts that we put in on the outside of our base rail was just a regular hex type bolt. Well, that actually drops through this bed corrugation here. So up inside of there, you can see where that bolt is coming down.So to secure it, we're going to take this included tool, and I put a slight little bend in it, and we're going to take one of these spacer blocks that has the nut kind of pre-attached to it. Put your tape on there, facing up towards the bed. It's going to drop in there like that, just like this. And what you're going to do is very carefully line it up and push it back in there. What I'm going to do is just hold this in place, and I'll have a friend get up in the bed of the truck and turn the head of that bolt. That way this will get started and become tight.This is what that fastener is going to look like once we have our bolts started hand tight. You want to do that on each side.Now we can get the rest of our hardware started hand tight as well. We're going to start with this bolt right here. What you're going to want to do is take a spacer block, the U-shaped one, and put that special tape on it. It's actually going to take up that space in between our frame plate and the bottom of our bed. So this is going to slide in here like this. Then what we can do, let's take one of our offset flat spacers. Put that on. We're going to take a flat washer, a split lock washer, and a hex nut.Now, for our two bolts here in the center of the truck, they can be a little tricky to get to if you're spare tires is in place. So what I went ahead and did was just temporarily lower and remove it. That way we have a lot more room to work down here. If you look here in the middle, you're going to see our two bolts coming down from the bed. They're both going to use that same hardware combination, which is a offset flat spacer. With these, you want to make sure to put that tape on there. We'll slide that on, followed by a flat washer. Grab a split lock washer, put that on, and finally, a nut. Get that hand tight and do the same thing for this bolt here.Now we can find the location for our forward base rail, and to do this, you're going to need the fifth wheel base that you plan on using. We have ours here. You set your rail up in front of the rear rail, and then you're just going to take your base and put it into the back rail and simply just line up the front with it. You want it to drop in place and sit nice and flat. Once you have it in, you can take your fifth wheel base, push it towards the back of the truck, and then you're going to take your front rail and slide it towards the front of the cab as much as you can. Now that we have it setting like this, what I'm going to do is take a measurement and make sure that our rail is centered, just like we did the back.Now that we have everything centered where we want it, we can mark our holes that we need to drill. We're going to be using these two on the outside. We're only going to be using one in the center this time, and that is this one here that's closest to the front of our truck. And on the other side, it's the same. So just these two end ones. Once we have these marked, we can take our fifth wheel base and rail, set it off to the side, and then we can drill these holes out with a pilot bit, just like we did the one on the back.Once our pilot holes are made and you've used that same technique with the wire to make sure that your holes do indeed line up with the frame plates, which I've done, we can come back with our larger bit and open them up completely.With our holes drilled, we can come back again and vacuum up our mess.Now that our holes are drilled, I used the black marker to cover up that bare metal, just like we did the other one, set our rail in place, and now we can get our hardware going through. Let's start with the one here in the center. It's going to get a U-shaped spacer block. Again, put that tape on it, just slide underneath the rail. Take our carriage bolt and just drop that down through. If I can get it to line up here, it should go right into position. And as far as the ones on the ends go, these are just going to receive carriage bolts as well.So now here in our wheel well, you can see where our hardware passes through our front frame plate, and just like the back one we did earlier, we're going to take a U-shaped spacer block with the tape on it, sneak it behind there. And again, this is going to fill that gap in between the bed and our frame plate here. So we'll push that up against the back of the bolt. Kind of tricky to see, but you can actually feel it and get to it pretty easily. So I have that in place. We're going to take our offset spacer there, slide that on. Flat washer, a split lock washer, and a hex nut. So we'll get this one hand tight.You have to kind of push up a little bit to get that nut started, give you enough threads. Now that that one's going, I'm going to use that same exact hardware combination for this bolt as well as the ones on the other side of our truck.For the one here in the center, we use that same hardware combination. We use that offset spacer block. Don't forget to put your black tape on it. Flat washer, split lock washer, and a hex nut. So you get that hand tight as well.Now, what we can do is start to tighten all of our hardware down and we're going to do this in a particular order. We're going to tighten down the three holding on our mounting rails on the side here first. So we'll grab a 19 millimeter socket and snug them up.I'll go over to the other side of our truck and do the same thing. Then we can tighten down all three of our bolts here in the center underneath the truck.Then we can hop up in the bed of our truck and tighten down our two hex bolts. Then we can come back to our frame plates and tighten down our two bolts, holding it into position. We'll do that on the other side as well. Now we can use that same tightening sequence to actually torque all of our hardware down to the amount specified in our instructions.And that'll finish up our look at and our installation of the B&W custom fit installation kit with base rails for a fifth wheel trailer hitch on our 2020 Ford F250.
