Video Transcript for Bulldog Adjustable Gooseneck Coupler Review

Randy: Hey guys, Randy here at etrailer.com. Today we're taking a look at a gooseneck coupler from Bulldog. This is one of the auto-connection styles. The thing I really like about this one and the thing that sets it apart from a lot of the other ones out there, that when we back underneath this, all we have to do is operate our jack, lower the ball down. As we do, the lever comes up, grabs ahold of the ball, and is gonna reattach behind it. We don't have to get in, push the tongue side to side, push the trailer side to side, try to get a latch and a pin set.

It's gonna be a really nice, quick way to connect.Here's a closer look at how the coupler attaches to the ball. As you can see, we've got it just a little bit off-center. It's gonna self-guide. But it also self-latches. As we continue to drop it, we'll see our arm come up and out of the way.

Once it gets below the ball, it's gonna go back down. At that point, our trailer's coupled. This is gonna prevent us having to climb in and out of the bed of the truck each time.To unlatch our coupler, we'll raise our trailer slightly. We're gonna raise the ball slightly. Gonna put just a little bit of preload on it there.

Then as we pull our release handle, we'll see it pop up just a touch.Another nice thing about this setup rather than a fixed, maybe just a fixed weld-on, is that this is adjustable. If we change trucks, if maybe one truck's higher than the other one, we can adjust this up and down as much as eight inches. That helps us to keep a nice, level trailer, make sure that we have a good trailing experience.We've also got the grease circ right here on the back. That helps us to service and maintain our auto-latch there so this'll operate and be nice and smooth for a very long time.As far as weight ratings go with it, we have a 7500-pound vertical load limit. That's the maximum upward force that we can put on our coupler.

The maximum gross trailer weight's gonna be 25,000 pounds. That's gonna cover a lot of different applications.You can see the gray paint here. This is gonna act like a very good primer, or you could use it and run it just like this. You can also paint this to match your trailer if that's something you'd prefer.Depending on how you're starting your installation process, that's kinda gonna change how we get everything put on. Since we do have a new replacement outer tube, if you need it, you can weld it on. Maybe you've got a new trailer build you need to add it on. Maybe this one's gotten damaged one way or another. It can happen. Basically we'll remove the old one, clean up our welds and metal there, and this one's gonna fit right in. As you can see, right at that 20-inch mark. Very, very common size.The one thing I will tell you . With any of these replacement tubes, there's no cap on it. There's always a cap on these goosenecks here at the top. That prevents moisture from running down in. So if you are gonna weld on your new outer tube, just be sure to put a cap on that so you don't have rust issues internally.Once we've got that portion settled, we need the actual coupler. This is gonna slide up and in our tube. You'll see we've got four holes there to choose from. We want the bottom of the coupler to be where our trailer's sitting level at bed height. We'll bring that up to an appropriate slot. They've provided a new pin for us. You see a nice pin with the clip attached. Need to slide that through one side and out the other. We're gonna use our clip to secure it. I'm gonna go around that way. Just like that. Now we'll need an inch-and-an-eighth wrench. We can tighten down our set bolt.Generally for the set bolts on this trailer and also on the replacement coupler, you're gonna need an inch and an eighth. We'll bring that bolt down so that it makes contact. We don't want this lock nut to be down and engaged yet. Once it makes contact, we need to torque it down to specifications. Generally on this three-quarter-inch bolt, you're gonna be looking at 125 foot-pounds. We'll get it where we want it there. Then the jam nut, we wanna take that back in that way. Just like that. Then we can slide a box-end wrench on it, just give it a little bit of torque to ensure this bolt doesn't back out.With the jam nut tightened down, you're gonna need to add a cable. This is not supplied, so either grab the one off your old coupler if it had the auto-connection type like this with the lever release, or you can just use a bolt. Grab yourself a cable. The coated cable's generally good. You don't have to worry about rust. You'll just run that back so you can get ahold of it. As we pull that, you can see that releases that catch. This is gonna prevent us getting up in the back of the truck or keep us from having to climb up in the back of the truck and release our coupler. We just pull our latch here, operate our crank, and raise it on up.

I really like how the coupler works. After running a cable to the handle, I never have to get in the bed to connect or disconnect the trailer from my pickup. The only thing I don’t like is, I cannot find a lock for it. 664433

Excellent product, I wouldn’t change a thing!

I thought the cable for the latch came with the couple, did not receive, other than that every thing was good. 829667

Worked perfect. 786276

- BD0289340317

coupler-perfect tool for older short man or woman to hook up trailer in these tall pickup beds. 784703

- BD0289340317

The product was easy to install all I really needed was the insert. I already had a unit on my other trailer. I wouldn't be without one on the trailers . It makes hooking up so much easier. Well worth the money! 633977

- BD0289340317

haven't installed yet, but I expect it'll be just fine. hard to find item and since I planned my project out months in advance, the few weeks I had to wait on it was not a problem. 519333

- BD0289340317

Love these!! I added a pull cord and don't even have to touch a thing! Great product and excellent service getting here! Good job all around. 402518

- BD0289340317

I have a gooseneck adapter on my 5th wheel that is VERY similar to this one, and I LOVE it!! It has a cable that runs from the latch up to the neck, and out, so I just pull the cable to un-latch... no climbing into the bed!! It also auto-latches as you lower the hitch onto the ball, which is nice! This one is going on a trailer I'm building, and I'm sure I'll like it just as much! E-trailer is always great for information and orders ship fast and correctly. I'll be back for more, I'm sure!! 306016
