See what our Experts say about this Bulldog 5th Wheel Gooseneck Adapter

• Adapter Solution to Convert Gooseneck Trailer to Fifth Wheel King Pin
  We have gooseneck trailer to fifth wheel king pin adapters that would work great on your trailer but it really depends on what type of gooseneck trailer you have now. For example if you have a square tube gooseneck you could use the part # BD028965030 or for a round tube part # PKG5-R25-IP. Or you could replace the outer tube as well and use the Bulldog # BD0289590300. For an air to electric brake controller the Hayes part # HA100400C is the kit you want. This ties into the air brake setup...

• Adapters to Allow Towing Gooseneck Trailer with 5th Wheel Hitch and Base Rails
  If you have a set of industry-standard above-bed 5th wheel base rails in your truck you can tow a gooseneck trailer by installing an adapter such as the Curt Spyder # 16085 or the Curt 25k # 16055. All of these 5th wheel rail gooseneck adapters are standardized to fit into any brand of 5th wheel base rails. Note that some of these like the Pro Series have offset ball placement which gives you the option to install the plate with the ball either more forward or more rearward which alters...

• Square Tube Gooseneck Coupler Adapter Recommendation
  We offer 2 square tube gooseneck-to-fifth-wheel coupler adapters, the Redline Coupler Adapter, # KPG5-Q25-IP, and the Bulldog Coupler Adapter, # BD0289650300. These are quality couplers that would do an excellent job. If I were choosing one of these couplers, I would go with the Bulldog coupler because it has a wider bottom plate similar to a fifth wheel pin box that will make more contact with the fifth wheel hitch. It also has a small curved lip at the front of the plate making it easier...

• Recommended Wiring Conversion for Semi Truck and Gooseneck Trailer with Electric Brakes
  The Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter - Inner Tube # BD0289650300 will work with a Semi Truck Connection.

• Can a 5th Wheel King Pin Adapter be Installed on a Big Tex 22GN Gooseneck Trailer
  I looked up the Big Tex 22GN Gooseneck trailer and see that it has a square tube coupler. We do have an adapter, inner tube only, for square tubes, # BD0289650300. The tube is 4 inches wide on the outside. It uses holes for pins or bolts though so if the inner tube on the trailer now doesn't fit the same way then either the outer tube would have to be modified with permission from Big Tex or the adapter would have to be welded on and again with permission from Big Tex. There are other...

• Gooseneck Hitch Recommendation for Peterbilt Single Axle Semi Trailer
  I do have a solution for you, however, the B&W Turnoverball # BWGNRC912 you referenced is not your best option. Instead, take a look at the Buyers Products 2-5/16" Fabricators Flatbed Gooseneck Hitch # 3375613500. This heavy duty hitch is designed to be welded onto a 1/8 inch, or thicker, floor plate and has a much smaller footprint than the BWGNRC912. The hitch plate dimensions are 6 inches wide by 8 inches long. It has a capacity of 30,000 lbs as well. I've included the installation...

• Swapping King Pin Setup on Kaufman Car Hauler Back to Gooseneck Setup
  I looked up several pictures of the Kaufman 3/4 car wedge and I couldn't find any that showed it having a fifth wheel king pin instead of a gooseneck. The ones I found all had gooseneck couplers which yours could have had swapped to a king pin setup but I'd have to see the setup to be absolutely certain. Most likely the trailer had a gooseneck setup like the part # BD0288660300 you referenced which has an inner and outer tube and a fifth wheel adapter was installed on it like the part...

If the inside width of your outer tube is about 3-1/2" then this coupler adapter won't fit. All of our other square inner tubes have the same 4" outer diameter.

• Availability of Gooseneck to 5th Wheel Hitch Adapter for 2015 Big Tex 25DU Gooseneck Dump Trailer
  If your truck has a fifth wheel hitch that uses industry standard rails (like those sold by Reese, Curt, Valley and Husky), the easiest way to tow the trailer would be to use a gooseneck ball that attaches to your bed mounted rails like the Curt # 16055. Big Tex tells me they used a Bulldog 4 inch square tube coupler on your trailer, so if your fifth wheel doesn't use industry standard rails, you'd need to remove the existing coupler and install the # BD0289650300 Bulldog Gooseneck to...

• Recommended Gooseneck to 5th Wheel Hitch Adapter
  It sounds like your 5th wheel trailer already has what it needs and you just need the adapter for the Ram Gooseneck if I understand correctly. If your gooseneck hitch has a round tube, then I recommend the Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-R30IP. If it has the square tube, then I recommend the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter Inner Tube - Square - 30,000 lbs # KPG5-Q30IP which has a 4 inch tube. Both options have a plate that is 9-7/8 by 9-7/8 inches....

• Availability of Inner Tube Gooseneck to Fifth Wheel Adapter that Measures 4-1/2 inch by 4-1/2 inch
  I wish we did, but everything we carry has an inner square diameter of 4 inch by 4 inch.

You would need to measure the opening at the bottom of the outer tube though.

• Availability of Gooseneck Coupler to Fifth Wheel Hitch Adapter for 4-1/2 Inch Wide Coupler
  The best option I have that would work for you would be to remove the existing square outer tube from your gooseneck trailer and replace it with part # BD0289590300 which includes the outer tube that would weld onto your gooseneck and the compatible inner tube that would act as the adapter. When you tow a gooseneck trailer, you'd swap out the adapter and install a gooseneck coupler like part # BD1289210300.

• Adapting a Gooseneck Trailer to be Towed By a 5th Wheel Trailer Hitch
  All of the square inner tube gooseneck trailer to 5th wheel adapters we have are 4 inches wide so you will want to look at other adapter options. If your 5th wheel trailer hitch sits in above the bed rails then you can use a gooseneck plate, # 16055. I have linked a couple of videos of this hitch for you. If you do not have industry standard above the bed rails let me know what you do have and I can determine if there are other options.
