How to Install the Reese M5 5th Wheel Trailer Hitch on a 2021 Ford F-450 Super Duty


Hi there Ford owners, today in your 2021 Ford F450, we're gonna be taking a look at, and showing you how to install, Reese's M5 fifth wheel hitch, for Ford vehicles, with a prep package ,for fifth wheels. You can get this at either a 27 K or 20 K model. We're showing off the twenty seven K today. Now, if you have a factory puck system, a hitch like this, it's going to install extremely easy. You do have to do a little bit of pre-assembly, to attach the parts, once you get them from the box, but once it's assembled, you can either do it in the truck bed which we're gonna be showing you how to do, Cause it's easier to do, if you're doing it all by yourself, or if you've got a friend there to help you, you can assemble it out of the truck. What you'll want to do to remove and insert your fifth wheel hitch, for the whole assembly.

Let's say maybe we're getting ready to go pick up a load, we need to get the fifth wheel out of here. We pull our pin there. And then once you've got your handle's loose, you can see here the fifth wheel we'll just lift right out of it, now I do recommend an extra set of hands, for a fully assembled unit here, I'm not gonna be pulling the whole thing all the way out. And when you're ready to put it back in, it's just as easy, You just got to turn your handles, until they line up with the pucks. Sometimes you do need to go over to the other side just to give a little lift, to get it all lined up and then you can just turn your handles and re-install the clips to reattach it.

And instead of using the included bail clip, you could put a padlock on there as well to protect your investment. And what's great about a fifth wheel hitch like this, is that there's really almost no installation. There's no above bed rails or under bed kit that needs to be installed. It just drops right in. And then when you go to take it back out, since it's a nice factory set up, the attachment points have plugs that cover them right back up.

And it's like, you don't have a fifth wheel at all, you are back to just a full truck bed. Now when you're ready to tow, first thing we'll do is remove our bail clip, get that out of the way. And then we'll take our handle here, We're just gonna pull the handle, and that's gonna put us in our unlatch position. There's a couple of things that happen to let you know, that you're in the ready to accept position, to hook up a trailer, One, the handle will easily pull towards the cab of the vehicle, and when you let it go and it snaps back into place, it's not gonna line the bale clip holes back up. So we're not gonna be able to re insert our pin, and there's also an indicator here on the side of the head, that changes from green to red, red being ready to accept.

And the alignment hole for our bail clip will wind back up. We'll wanna make sure that we have this clip, is reinserted and fully installed, before we take off with our connected trailer. Now that we've gone over some of the features of our hitch, we'll go ahead and show you how to get it set up in your F four 50. We'll begin our installation by getting everything set out. All your parts are gonna come in several large boxes. You'll probably get about three. That's gonna have all your parts in it. You'll have your legs, your center section as well as your head. The head doesn't come in the same box as center section, I just set it on top. It's loose, it's just sitting on there. You'll also get a handle and all of your hardware. So I recommend just laying it out cause there's so many boxes and pieces. It's best to have them all there, so you have everything you need and ready to go. Take our legs, I've gone ahead and peeled the plastic off of them, you could assemble it outside the truck, and then lift the whole assembly in. If you have an extra set of hands around, that might be an easier way to do it. And once you to assemble the whole thing, it becomes significantly heavier. So if you're doing this by yourself, we're gonna do it this way here in the bed of our truck, to minimize the weight. We're gonna start by popping off the caps here, they might be on there pretty stiff, so you might need to get a flat-bladed screwdriver underneath of it just to help you pop it up, and we're just gonna go ahead and remove all four. We'll then take our leg assembly, we are gonna go ahead and pull the pin out of it, Just lift up on the ring. That'll allow us to turn the arms, we'll have to open them up, so you can see here that, they are angled, front to back, so that way they'll slide down into the puck system there. Once you've got it done in there, push the arms back over, and go ahead and re insert your pin. And you can verify here that, it's not gonna come out of there. We'll go ahead and grab our center section now, so you can go ahead and get that attached to this one side, and that'll make it much easier when we go over to the other side, to attach it and get it in on the other side. We've got our center section here and we put the labeling here towards the rear of the truck. If we look at the side of the center section, we can see that there are three rows of three holes. We're gonna be using the ones at the front, and at the back, the larger ones. And those are your adjustment for the height of your fifth wheel. You wanna set it up to where you have at least six inches between the top of your bed rails on your truck, to the bottom of your fifth wheel trailer. So that way you've got plenty of clearance there, for movement. We're gonna be using the middle set of holes, and we need to make these own measurements to determine your trailer for when it's hooked up, so you pretty much take your trailer and make sure it's level, take the measurement from the ground of the trailer, and then while your trucks level, take the measurement from the ground to the rail, So you can get an idea, of that distance, to where you are gonna set this. So we're goinna be using the middle holes for that for the medium height adjustment, we'll take the bolts that come included with the legs. You should have four of them there. The large thick bolts here, we're gonna place conical tooth washers on them, with the teeth facing away from the head of the bolt, and if we look at the attachment here where it's going to thread into the leg, it actually sticks out just a little bit, this little extrusion here, where it sticks out, needs to actually go inside the hole. It's kind of like an alignment pin, same with the rear one here. So we're just gonna lift this up here, line up our hole, and then get the bolts started. We don't really need to worry about lining up the alignment peg, until we gotta fully tighten it down. So that's why I like doing it like this, cause that way ,it's a little bit easier to line things up, that we don't have to hold nearly as much weight while we're doing this, just line up the holes, and loosely start them. Now we've got those loosely started, it's best to have your hardware already prepared, and then we can drop this leg down in there, and get this side attached. So we just set the legs in there and lock the pucks down, now we're just gonna line this one up, and get these bolts started. Now we've got them loosely installed, we're just gonna tighten 'em down. You'll want to use a 24 millimeter, to do so. You might need to use a wrench, You could potentially get some tools, in the larger section here as well. If you've got a small electric gun as well, you can fire them down with that as well. It is important that this stuff, that when you're running them down, to pay attention to the side here, we don't wanna have a gap, when you wanna make sure that alignment pin, is inside the hole. Once you've got 'em all tightened down, you verify this flush and your alignment pins are lined up, You can go back and torque it to the specifications, outlined in your instructions. We'll, not roll off..
