Review of the B and W Companion OEM 5th Wheel Hitch with Slider

Today we're going to taking a look at the BMW OEM fifth wheel hitch with slider for Chevy or GMC towing prep package. Part number BWRVK3770. Here's what our fifth wheel with slider looks like when it's fully installed. Since we have a short bed truck it's going allow us to tow a fifth wheel trailer and have enough clearance to make those turns without having to worry about making contact with our cab. If we come to the handle right here, start in a locked position, we can rotate it to the unlocked position. Then we're going to have 12 inches of travel so the fifth wheel can go farther back towards the tailgate, we can make our turn. Then once we straighten out, we can again, come to the handle, unlock it and it'll slide back into the towing position.

Now this fifth wheel slider is designed to work with the GM and Chevrolet factory prep package and that's what these handles here are. It's going to sit in and lock into place. Our fifth wheel head is going to feature a dual jaw system, so it's going to have a full 360 degree king pin contact, which is going to reduce some of that noise we hear when we're going down the road. Underneath our head here where it mounts to our base, we're going to have two large polyurethane pushings, which not only are going to give us a secure place and our heads going to mount to, but it's also going to provide a little bit of cushion and cut down on some of that noise and rattling when we're driving down the road. Our handle is going to feature a tethered safety pin so we don't have to worry about losing it and when we're ready to hook up we can simply rotate the handle back. There's actually a small notch back here that we can put our safety pin in that'll leave our fifth wheel open so we can get ready to hook up.

Once we do bring our trailer in and the king pin makes contact it's going to push and then we can rotate our handle back, and then again, making sure it's secure with the pin and clip. We do have three height adjustments. It's going to be a little hard to see in this particular position, but these arms here are bolted to the inside of our base. They're going to go at the lowest setting to 17 inches, the middle settings going to be right around 18 inches, and the highest settings going to be 19 inches. Our hitch is going to feature a 5,000 pound vertical load limit, along with a 20,000 pound gross trailer weight limit. Now I do want to mention, you always want to double check your vehicle' owners manual to make sure it can handle that amount of weight, and you always want to go with the lowest setting of your entire towing system. Now our hitch is going to feature a steel construction with a nice gray powder coat finish, which is going to set it apart from most others because most others are going to have a black finish on it. Although our fifth wheel is rather heavy, since it does use the factory prep package, if you have an extra set of hands you can pull the head off, pull a couple pins, rotate some handles, and then lift the base out, and you'll have full bed access in just a few minutes. Now that we've gone over some of the features and benefits of our hitch, let's show we get it installed.

To begin our installation we're going to come to the bottom of our base here and we're going to pull the pin and clips out and we're going to rotate the handles so they're facing outward. Now we're going to need to do that on all four points around the base of our hitch. We're going to take our base and we're going to set it into the puck 00:03:28 system in our truck. Once we have our base securely in, the puck system in our bed, we're going to take our handles and rotate them into the locked position. With all of our levers adjusted we can go ahead and re-secure them with the pin and clips. With the base mounted, now we're going to aim to mount the arms so we can put the head on top.

Now we're going to have a different positions that we're going to be able to mount the head. On our application we're going to be using the lowest setting. Now we can take our arm and again, in our application because it's a short bed truck, we're going to take this straight part of the arm here and that's going to be going towards the tailgate so that it sits farther back giving us that much more clearance before our trailer hits our cab. At the lowest setting we're going to take this bottom whole on our mount here and we're going to line it up with the very bottom hole on our base here. The way we're going to attach these, we're going to take a half inch bolt and a half inch lock washer and we're going to line up the holes and we're going to secure them into place in all four of those holes and we're going to have four per side. We're going to get the other side in as well. Now once we have all of our hardware in place, come back, and using a three quarter inch socket I'm going to snug it all up. Again, using a three quarter inch socket, I'm going to come back and I'm going to torque all my hardware down and then you're going to get that torque value from our instructions. We're going to repeat that for all of our hardware. We're almost ready to put the head on our fifth wheel, but we have a few minor things we need to finish up. We're going to have a spring clip. If we notice, one end is going to have a small ear that comes off of the loop. We're going to line up the hole on our clip with the tab that has it coming off of the loop. We're going to take our quarter inch bolt. It's a very short bolt. We're going to go through the bracket and the spring and then we're going to secure it with a lock nut on the back side. Then I'm going to take two seven-sixteenth's wrenches and tighten it up just so it's a little snug. You don't want to crank it down right now, because we're going to have to mount the spring clip to our arm. You can take two seven-sixteenths wrenches, one to hold the bolt, and then one just to snug up the nut on the back side. The metal clip we're going to see has a slight section and that's going to mount to arm here, but when we get it into position the top piece of this rubber here, we're going to want to have about a half inch of clearance between the top of our spring here and the bottom of our mount. Once we find a general spot that's about there, you're going to want to push firmly to hold it in place. Now we're going to take either a hammer, a rubber mallet, or whatever you have and we're going to need to drive this onto the arm. We can go ahead and take the head now. We're going to want to lift by these handles and get ready to put it in place. Where are handles are, it's going to sit right over those rubber pads. If you notice, we do have pins in place. We're going to remove the clips and pull the pins out and let them hang for right now. We're going to do that on both sides. Now if we come back to those handles, we're going to lift up on the handles while pushing down on the head of our fifth wheel. We can see that they lock back down and that's going to keep the head secure. For secondary securement, that's where the pins and clips are going to come into play. We can go ahead and reinstall those. One final step, we're going to attach our handle. Now we're going to have a tethered pin. We can go ahead and remove the clip holding it in place and we can pull the pin out. Now we're going to take our handle with the label facing up and the handle towards the back of our tailgate, and we're going to slide it into position and it's going to automatically line the holes up. Now I mentioned that are safety pin does go in this first hole. We can go ahead and put it back in place, that way we won't have to worry about getting mixed up and confusing which hole we put our hardware in that's going to attach our handle. We're going to have a couple hex bolts here. We're going to drop them down through the holes and then we can come back and take our flange nuts and attach them on the bottom. I'm going to come back and using a 732nd Allen socket and a 916th's wrench I'm going to smug up my hardware. That'll finish up our look at the BMW Companion OEM hitch with slider for Chevy or GMC prep package. Part number BWRVK3770.

Can you haul your fifth wheel with the slide all the way back all the time

When you're towing the slider will need to be back up into its towing position - it should only be slid back when making tight turns that require cab clearance.
