This allows you to tow your fifth-wheel trailer without a bulky fifth-wheel hitch. The Ranch Hitch from Andersen Manufacturing is easy to install, even for the inexperienced do-it-yourselfer.


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.

Video Transcript for Review of Andersen Gooseneck and Fifth Wheel Adapters - Adapts Trailer - AM3100

Today we're gonna take a look at the ranch hitch universal 5th-wheel-to-gooseneck straight coupler adapter. This heavy duty adapter will convert your 5th-wheel trailer kingpin to a gooseneck coupler, so it conveniently allows your 5th-wheel camping trailer to be towed with a gooseneck hitch. The adapter here will bolt to your kingpin on your 5th-wheel pin box, and it attaches to the gooseneck cup for in your truck.This part will include everything we've got laid out here on the table. The straight adapter with the remote cable latch and bracket attached; the threaded collar assembly, right up here at the top you can see, here's the threaded collar; and then you'll notice there's two split collar halves that'll go in there, this is what'll go around your kingpin on your pin box; it comes with a spanner wrench that is used to tighten this up to your threaded on and tighten it up to your pin box; and all the mounting hardware you need to install it, and a nice installation manual that'll describe how to install everything and how everything operates.The remote coupler release right here, this is what'll let you engage and release the coupler while standing alongside your truck, so it eliminates having to climb in and out of your truck bed to release it. Basically, there's a pin right in here, so when you pull this handle open, that pin'll slide across, allow it to drop you onto the gooseneck ball. Once it drops on the gooseneck ball, you push that into place, that pin'll slide across and lock it into place.

And then you can just turn this handle to lock it so the handle won't open.It does allow three-inch vertical adjustment, so it allows towing with multiple vehicles. You can see here, three-inch range here, and then you have the set bolts to set it into place to get it level.It is a do-it-yourself installation, takes less than an hour to install it. Again, it's designed to work with standard 2 5/16 diameter gooseneck hitch balls. The part is made in the USA.Specs again, the application for this, to determine if this adapter will work on your 5th-wheel trailer, what you'll wanna do is back your truck into position as if you're hooking up your 5th-wheel trailer, making sure that the truck and trailer are level, and then you'll measure from the pin plate, which is the bottom of your pin box, down to the top of the gooseneck ball in the bed of your truck.That measurement you should get should fall between 11 3/4 and 14 3/4, and the reason they say that is this adapter, when it's fully compressed it's 11 3/4 inches tall, when it's fully extended it's 14 3/4.The required clearance between the overhang of the trailer and the top of the side rails of your truck for safe operation should be at least five or six inches. This will work with trailers with standard or extended pin box, but one thing you do need to make sure is the extended pin box cannot be longer than 24 inches measured diagonally.

Basically, to show you how to measure that, again, if you go to the product page of this part number, there's a picture of how to measure it to make sure it'll work with your extended pin box.Weight capacity on this is 24,000 pounds, tongue weight capacity is 6,000 pounds. They do also offer an optional slide hammer to help ease installation, we do sell that part separately, part number AM3103, and that'll help you install these collars to the kingpin and remove them.The safety chains, we do sell those separately to use on this. And one last note that I do recommend, this adapter is designed to be used with standard static pin boxes only, it's not to be used with a cushioned or air ride pin box.But that should do it for the review on the ranch hitch universal 5th-wheel-to-gooseneck straight coupler adapter.

The hitch was shipped the same day it was ordered. It arrived in five days in excellent condition and with no parts missing. It took me longer to install it because I had to remove the king pin box component to drill the bolt holes and mount the bolts to provide the additional support I wanted. An excellent product and a good price. 287365

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 - 08/14/2013

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.

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 T - 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/secure 11335

The Ranch HItch 5th wheel adapter AM3100 was everything that we needed and more!! It fit perfectly and was a breeze to install. We will be pulling our "home" around the country when we retire. We didn't want to have the back of the truck to be full of "hitch" with no room for much else. The Gooseneck adapter is the perfect choice for us!! GREAT PRODUCT!!! 457631

    Usually on a Ford F-250 long bed (8 foot) truck an offset gooseneck adapter is not necessary, but you can measure to see if you would need one. To determine the clearance needed on your F-250 long bed, you need to take the width of your trailer and divide by two. Then measure from the gooseneck hitch ball in the truck to the back of the truck cab. That dimension should be 4 inches more than your first measurement for correct clearance.

  • How Much Clearance is Needed Around a Gooseneck Trailer Hitch Ball for Toolboxes
    The amount of clearance you will need around the gooseneck ball is going to depend on the trailer coupled to it. If you were using the Ranch Hitch adapter # AM3100 to tow a 5th wheel trailer using the gooseneck hitch then at the widest point, where it attaches to the ball, is 5-1/2 inches. So you would need more than 5-1/2 inches all the way around (measured from the center of the ball) if using this adapter. I would say if you had 6-1/2 inches all the way around that would allow for enough...

  • How to Measure to Determine the Correct 5th Wheel to Gooseneck Adapter
    You will need to measure to determine how long the fifth-wheel to gooseneck adapter will need to be. Park your fifth-wheel trailer on a fairly level surface. Back your vehicle under the fifth-wheel trailer stopping when the center of the king pin is directly above the gooseneck hitch ball, measure from the top of the gooseneck ball on the truck to the base of the pin box on the trailer.

  • Recommended Way to Lock a Fifth Wheel Trailer with a Ranch Hitch Fifth Wheel Adapter
    What I would recommend for your fifth wheel is actually a wheel lock since the Ranch Hitch part # AM3100 doesn't have a great way to lock it. The most popular option we have is the Rack'em part # RA-25 which would attach to the wheel of your trailer regardless of what coupler you have on your trailer. It has two sizes to fit basically any trailer wheel size. One side works on 12"-15" wheels, the other 15"-20" wheels. Check out the review video I attached for more info as well.

  • Towing Fifth Wheel with Air-Ride Pin Box Using 2000 Ford F350 with B and W Gooseneck Hitch
    Fifth Airborne and TrailAir, who manufacture the air-ride pin boxes we carry specifically state that they are NOT to be used with gooseneck adapters. The gooseneck adapter can already place stress on the frame of the 5th wheel. If you add some flexibility to the connection between the adapter and the king pin, like what you get with an air ride pin box, the stresses on the frame and the gooseneck ball could increase to dangerous levels and cause a failure. These adapters are not what I...
