Measuring Your Truck and Trailer for the Ranch Hitch Coupler Adapter

You can perform these steps to determine if the adapter will work for your fifth-wheel trailer.

  1. Back your truck into position as if you were hooking up your fifth-wheel trailer, making sure that the truck and trailer are level.
  2. Measure from the pin plate (the bottom of the pin box) down to the top of the ball in the bed of your truck.
  3. The measurement should fall between 11-3/4" and 14-3/4". (The adapter is 11-3/4" tall when fully compressed and 14-3/4" tall when fully extended.)

Additional Measurements

Five or six inches of clearance between the overhang of the trailer and siderails of your truck is necessary for safe operation.

Measuring for Pin Box Length

The Ranch Hitch adapter is designed for trailers with a standard or extended pin box up to 24" long (measured diagonally). To find this dimension, you should measure from the centerline of the bottom of the king pin into the back of the pin box as far as you can reach. You may not be able to reach the very back of the pin box itself because the top of it may extend into the trailer. In this case measure to where the pin box disappears into the trailer.

I have pulled my camping trailer approx. 300 hundred miles since I installed the adapter. It works great. Installation was pretty simple, the only difficult part was drilling the four holes thru my fifth wheel box. E-trailer service and shipping were great!112247

Seems to be a very well built product. Good price and shipped fast. Fairly simple to install, I recommend having a friend or two around to help tighten everything down. Also I preferred to bolt rather than weld ( unless you have a closed off pin box), you never know when you may need to go back to fifth wheel in a hurry.90774

How does collar system attach to king pin ? Thanks

comment by: L Thrash - 11/19/2013

There is a threaded collar that is fitted to the king pin. You would slide the coller up on the king pin. While holding the collar, you will take a split collet and fit that where the jaws normally grab the king pin. You will slide the threaded collar over the split collet and using either a pulley puller or Andersens hammer to seat the collar fully onto the split collet. I have added a pictorial of this portion of the instructions to the photo gallery and linked it here as well. The base of the adapter threads onto the collar and is tightened to ~1200 ft. lbs. The process for getting that much torque is outlined in the instructions and uses the included spanner wrench and a 4 foot cheater pipe. Finally, you will use either the inlcuded four Grade 8 bolts or four 1 inch tack welds to finish securing the adapter to the pin box. If you want to be able to remove adapter, make sure you can access the inside of the pin box so you can use the bolts vs. welds.

Product shipped/arrived timely from eTrailer; installation instructions provided by Anderson Manuf are very clear/easy to follow. Hitch is very easy to install. Attached to 30' fifth wheel, 11,000lbs tow weight and immediately pulled the trailer thru steep hill country without any hesitation. Pulling cattle trailers/heavy hay trailers, i know heavy duty hitches when i see them and this is a great product; HIGHLY recommended. Remote latching mechanism is a great feature; it too is very solid/secure11335

I have an Ultra-Fab trailair air ride kingpin system on my fifth wheel. Can the gooseneck adapter be installed on that type of system?

comment by: Deriek E. - 8/14/2013

According to Ultra-Fab, the Trailair pin boxes are not to be used with any kind of gooseneck adapter where the pin box is adapted to attach to a gooseneck ball. You can however adapt the truck to accept a 5th wheel hitch. Your best bet would be a fifth wheel hitch that anchors into a gooseneck like the Draw-Tite Hi-Rise, part 9480 or a Curt Fifth Wheel Adapter plate like C16210 or 16310.

  • Is the Convert-a-Ball Gooseneck Adapter Quick and Easy to Install for Towing Multiple Trailers
  • The Convert-a-Ball Gooseneck Adapter, part # CAB-C5G-14 would be the best part for you. It is very quick to install or remove, just a matter of tightening a few nuts and bolts. No drilling needed. The collar uses three allen screws to lock down on the king pin. The adapter then uses bolts to lock onto the collar. Pretty quick process. It may be easier if you have a second person to help hold up the adapter while you tighten the bolts and jamb nuts.

Make sure the trailer king pin is centered over the gooseneck ball and both vehicles are as level as you can get them.

  • Using Ranch Hitch 5th Wheel to Gooseneck Coupler # AM3100 on a 1999 Ford F-250 Super Duty
  • The set up on your 1999 Ford F-250 Super Duty certainly sounds like it was done correctly. If there are any issues, it probably will not be on the truck side. You will need to contact the 5th wheel trailer manufacturer to see if the Ranch Hitch, # AM3100, can be used. If the trailer has an extended pinbox, it will most likely need to have the frame reinforced by a qualified professional welder.

Plus, it has 3 inches of adjustability from 11-3/4 inches, up to 14-3/4 inches.

  • Generally speaking, you would most likely need more than 36 inches of clearance from the center of your axle to the cab of your vehicle, or in your case the welding machine that is in the back of your truck. There are many factors you should consider. First thing, how tall is your welder? How wide is it? If it is shorter than the overhang of your trailer it may not be an issue. Also, If the welder is pretty narrow and your trailer has a tapered nose it may also work. In order to determine

  • Recommended Gooseneck Hitch for a 2008 GMC Sierra and Trailer with a Ranch Hitch 5th-Wheel Adapter

Please note that if your truck has a 6-1/2 foot bed, you should be using a fifth wheel to gooseneck adapter that has an offset to give you enough clearance in tight turns.
