Video Transcript for A Closer Look at the Gooseneck to 5th Wheel Trailer Coupler Adapter

Hi there, I'm Michael with etrailer.com. Today we're going to take a quick look at this 25,000 pound gooseneck to fifth wheel trailer coupler adapter. This is going to allow you to replace your gooseneck coupler on your trailer so that you can tow your trailer with your fifth wheel hitch. This is going to eliminate the need to switch back and forth between your fifth wheel hitch and your gooseneck ball. And those fifth wheel hitches are pretty heavy. So it's most convenient just to leave them where they're at.

And so by switching this out, you'll be able to pull your gooseneck trailer with that fifth wheel hitch, as well as all your other fifth wheel trailers. So just have that one source of connection. It's also, in my opinion, a lot easier to hook up to a goose, or sorry, a fifth wheel hitch than it is to try and line up on that one pinpoint for your gooseneck ball. So you have that added convenience there as well. This does have a nice sturdy steel construction which gives us a max weight capacity of 25,000 pounds.

You can see this is a unique square coupler, that's going to fit in the same as your gooseneck coupler with the inner and outer tubes. Your inner tube here is right at 4 inches in width. Your outer tube is 4 1/2 inches. And you can see, we do have this 7/8 inch diameter load bearing pin here. That's going to allow us to adjust the height, so we can slide that outer tube along that inner tube.

Our outer tube has a height of about 20 inches, and then we'll have about eight inches of adjustability within that height range there. So we've got holes that are spaced about 2 11/16 from center to center. So that we'll be able to adjust in increments of 2 11/16 of an inch up to 8 inches in adjustability there to match your setup. You can see, we do have the two set screws here on the front that are going to make sure that once we have it set where we want, we can torque those down. Everything's going to be very solid for us.

The plate here, that's going to allow us to slide up onto our 5th wheel hitch. This is 9 7/8 of an inch long by 9 7/8 of an inch wide. Your standard size king pin there that you'll slide into your fifth wheel. So really nice set up here to transform your gooseneck trailer to work with your fifth wheel hitch. This does meet the S A E J 2 7 3 8 standards and is going to be compliant to meet those standards. So you can trust it's going to do a good job for you. It will be safe and it will allow you to pull that gooseneck trailer with your fifth wheel hitch. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

    The Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-Q25 is designed to replace the coupler tube of a gooseneck trailer to give you a king pin so that you could tow a fifth wheel trailer.

  • Setting Up A 2021 Dodge 4500 Flat Bed To Tow A Gooseneck Trailer
    To get your 2021 Ram 4500 flatbed set up with a gooseneck hitch, you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1500. This will require custom fabricated brackets to get it installed, but will be the best option we have available. This is American made, rated up to 30,000 pounds towing, and 7,500 pounds of vertical load, so it is very capable.
