Recommended Adapters to Convert B&W Gooseneck Hitch and Trailer to 5th Wheel Towing Setup

Question

Question:

I know to do all my trailer work through you guys! I am considering converting my 14,500 pound goose neck living quarter three horse trailer to fifth wheel configuration due to California trailering laws. I have the B and W Turn Over Ball hitch. It looks like the B and W Companion Gooseneck Adapter would be a good way to go...do you agree? And, if so, what conversion adapter would you recommend for the trailer? PS...I had my trailer in Missouri this fall...B and W trailered GREAT...all the way out and back from California!

Thank you for your support of etrailer!

Since you have the B&W Turnoverball Gooseneck Hitch, the B&W Companion Gooseneck-to-5th Wheel Trailer Hitch Adapter # BWRVK3500 will work great for you! The dual jaws provide 360-degree contact between the jaws and king pin, resulting in a more secure connection and less rattle than a slide-bar jaw. The Companion has a gross towing weight of 20,000 pounds and a vertical load limit of 5,000 pounds.

The Gooseneck-to-5th Wheel trailer coupler adapter I recommend is the Bulldog Round Inner Tube # BD0289640300. This adapter will replace the existing inner tube on your trailer. The large square plate above the king pin provides a larger surface area to contact the hitch than coupler adapters with smaller round plates. This coupler adapter has a weight capacity of 25,000 pounds.

I have attached a link to all of the gooseneck coupler adapters for you in case the Bulldog # BD0289640300 isn't a fit for your trailer.

I have also attached review videos of the Companion # BWRVK3500 and Bulldog # BD0289640300.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

We have lift kits for trailer that easily add 2 inches to the height of the trailer. For that you'd want the part #RR23QX and you'd be set. I attached a picture that shows how it installs to give you an idea. This would be the easiest…

Hey Mark, welcome to the fifth wheel community! I'd be more than happy to help you. So a fifth wheel hitch will sit lower than the top of the truck bed rails so you wouldn't have to remove the head of the hitch to close the cover BUT the…

Hi Glen, It will depend on what the GVWR (gross vehicle weight rating) is of your trailer to determine which B&W 5th wheel to gooseneck adapter will work best for you. Fifth wheels and gooseneck trailers go off of pin weight instead of tongue…
