Comments

did this adapter work on your semi tractor without welding on a bigger plate?You used it just the way I see it? I would use it on my semi if there is no problems.It looks to small for a tractor.

The kingpin, as you probably know, is the same size. Whether or not the plate will cause problems will have to be checked. The plate has a circumfrence of about 25-1/4 inches, a diameter of a hair over 8 inches.

I went out to the etrailer.com semi-trailer on our lot, see link, and produced a short video showing both of the king pins in close proximity to each other for you to see.

The tube is 4 inches outer diameter round so if you have an adjustable gooseneck, this part will slip right in. If you have a square tube gooseneck, you could use part # KP84HB. This tube is 4 inches square.

With this hitch installed you can flip the ball over when not in use to have full access to the bed floor. I have included links to the installation details and a video installation on a similar vehicle. When towing a gooseneck (or 5th wheel) trailer with a short bed truck like your 2006 Dodge Ram...

The plate is rated for 25,000 gross towing weight, but the capacity will be determined by your installation kit and the above-bed rails. The hitch ball on the gooseneck plate is offset from the center of the plate.

  • Can Wallace Forge Gooseneck to Fifth Wheel Trailer Adapter # 2085205 be Used With a Semi Tractor
  • Since the 5th wheel hitches on your semi and pickup both are designed for use with industry-standard 2-inch king pins either one can be used to maneuver your goose neck trailer as long as the trailer does not exceed the towing capacity of either hitch or your tow vehicle. According to the Big Tex website the 14GN has a gross vehicle weight rating (GVWR) of 14,000-lbs. The Wallace Forge adapter is rated for 30,000-lbs so it is more than up to the task.

  • Parts Needed to Tow a Gooseneck Trailer with a 5th Wheel Trailer Hitch in a 2006 Ford F-350
  • I think in this case the best option is to go with a gooseneck coupler that has a king pin on it like # KP84HB, that you have referenced. This is going to be the least expense and since it is height adjustable you will not have to worry about adding or height to the front of the trailer. For this coupler to work you would need to have a square outer gooseneck tube that will accept a 4 inch square inner tube. And the outer tube will need to have 3/4 inch diameter pin holes. If you...

Since you have a fifth wheel with rails already in your bed, I would suggest using a Gooseneck plate built for fifth wheel rails like Draw-Tite part # 49080. If you will be towing other fifth wheel trailers and need to keep your fifth wheel on the truck at all times and do not want to pull the fifth wheel on and off, we do have adapter tubes.

Or if you have a B and W square shank turnover ball hitch, use # 16310.

Then you can use the B and W companion hitch # BWRVK3400-5W.

We offer a weld-on 5th wheel hitch, part # RP30054 that would have more than enough capacity for your needs.

You should be able to adjust the height of the 5th wheel hitch in the truck if you haven't done so already.
