V-19 Certified for safety and featuring exceptional strength and versatility, this universal adapter converts a fifth-wheel king pin to a gooseneck coupler. 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.

I have been using the Ranch Hitch #3100 Straight Adapter for 3 years. Converting the 5th wheel to goose neck was awesome. Much easier to hook up and a smoother, quieter pull. After purchasing a new trailer I noticed that the trailer was too close to the cab of my short bed truck. I found the Ranch Hitch #3139 with 8" offset adapter. It installs easy and gives me 8 more inches away from my truck cab. Excellent! Turning corners is much more comfortable!

How do I install this? Do I have to drill holes? How long does it take?
-- comment by: Randy - 05/30/2014

There is a threaded collar that goes around the king-pin. The Ranch hitch is threaded on to the collar and tightened to 400 ft. lbs. Then you will either drill 4 holes into the pin box and install bolts, or use four 1-inch tack welds to weld the Ranch Hitch to the the pin box. This is a relatively permanent install.

After having this on my (small) 5th wheel travel trailer for more than 2 years, I have discovered the major problem with it...
Because the hitch point is so much lower, it has created unusual leverage over the kingpin box and now my trailer frame is cracking :(
Your trailer must be VERY shored up around the kingpin box to resist the extension of torque by essentially making your kingpin box much longer.
I loved the idea of not having a 5th hitch in the box of my truck and the removable gooseneck ball instead, but I now know that a complete change-out of the kingpin box to a gooseneck hitch would have been more reliable.
I am now in Mexico with a cracked trailer frame due to this :(



by:

Installed this hitch adapter on a small-ish fifth wheel trailer (2007 arctic fox 21-5R). I've waited to review now that I've finished pulling the trailer through the Canadian Rocky mountains to Vancouver island and back ~4000km or 2500 Miles.
The hitch installed fairly easily in about 2 hours, with careful attention to centering and torque specifications.
The hitch performed as it should throughout my recent trip, no problems with function whatsoever.
The only downside I see with this hitch adapter is the need to raise the trailer a few inches higher each time you hitch/unhitch, in order to clear the gooseneck ball. Also, when nearing a full 90 degree angle between truck & trailer, the pin box may rub against the bed rails. This is partly due to the ride height of my truck. Otherwise, excellent solution for avoiding the Fifth wheel hitch in your truck box!
Picture attached, dodge 3500 regular 6 foot box (levelling kit, 35" wheels) with arctic fox fifth wheel trailer. No modifications to trailer other than the ranch hitch adapter with offset for short box truck.



by:

I should have taken 5th whedel of trailer for easier installation but didn't have anyone to help remove it weighs quite a bit after installing gooseneck.. Still have it and no problems.



by:

Great Hitch with the 8 inch offset allows turning much safer in tight spots. Works great. I have had no issues with its operation.



by:

This product is great and just what I was looking for at the time. It was fairly easy to attach to the king pin to convert it to a goose neck ball which is what I already had in my truck bed. It attaches rely solid and can easily meet the 24000 lb rating I am sure. Being a short bed truck this hitch had the 8" offset which has the same effect as a 5th wheel slider hitch. The only problem with the offset is it puts the angular body of the trailer hitch closer to the side walls of the bed. Also when I remove the offset portion it also helps deter theft as there is nothing to hitch to! I have since bought a long bed diesel truck so I will be buying the straight adapter soon.



by:

Purchased this gooseneck hitch to convert my fifth wheel travel trailer to a gooseneck. This product is easily attached to the fifth wheel king pin and attaches very solid. The hitch release cable makes it simple to secure and release from your ball. I am very satisfied with my choice in purchasing this product and would highly recommend it. I have purchased this and other products from etrailer and have always received the best service.



by:

Hello, well I only used this setup for a couple of trips, I replaced it with Andersons ultimate 5th wheel connection. The 5th wheel box on my RV is extra long and was concerned of metal fatigue and cracking as was noted in some reviews. That was talked about in the instruction sheet. The product is solid ,would like to find someone that doesn't have a long box that could us it.



by:

Very heavy and solid. Quick install time. No disappointments, even shipped quick. Trailer pulled nice as well. Would recommend to anyone. I bought this because my Mega cab already had a gooseneck ball in the bed and I found a fifth wheel camper at a steal of a price. Adapter was extremely cheap in price but still a sturdy quality product. Converted the camper to gooseneck, and can still convert back if needed. Scott from PA.

great product,we installed the hitch in less than 30 minutes.This hitch allows you to haul additional items in the bed unlike a bulky fifth wheel hitch,once you detach the trailer you can remove the ball from your bed in 10 seconds.Thanks,will recommend your product to others.



by:

Hitch is great and a breeze to install. I cant say enough about the service I received from etrailer. I ordered the wrong hitch (my fault) so I called etrailer they immediately sent me a return authorization and shipped me the correct hitch. They shipped the replacement hitch on Thursday morning I received it Friday. Thats awesome. Thanks etrailer.



by:

The hitch was very easy to install. When we received it the release cable was damaged. I sent an email with pictures, in less than a week they sent a new one. Excellent customer service in my opinion!



by:

CUSTOMER SERVICE IS UNBELIEVABLE. I ORDERED THE ITEM WEDNESDAY AFTERNOON AND IT WAS AT MY DOOR FRIDAY MORNING. THIS IS NOT MY FIRST ORDER AND IT WILL NOT BE MY LAST. YOU GUYS KEEP UP THE WORK,
I HAVE NOT INSTALLED IT YET BUT I AM REALLY LOOKING FORWARD TO IT, THANKS RON, JACKSON TN.


Comments
Installation was easy, just followed the directions. I have used it for a year and I am very pleased with it. Really love how easy it is to connect.
RON F - 07/18/2016


by:

I still have to drill four holes and I had to rent a puller for $6.00 but so far I am impressed with how easy the installation was, but ask me again in two weeks when I have to move my fifth wheel, But for the price, and design compared to other adaptors, I have no complaints. Just not sure how well it will work with the offset.


Comments
Works great, for what I need. I do prefer the fifth wheel hitch, but did not want to put the rails in my truck for that hitch. I do have to use the backup balls and my camera for the goose neck hitch but its not too bad.
Mike S - 01/22/2015


by:

The hitch i ordered came quick. The finish on the hitch was badly scratched. It wasn't from the shipping the package it was sent in wasnt damaged.


Comments
I am sorry your product arrived scratched, Blake! The manufacturer says the powder coat is the toughest paint that is cost effective and should withstand a situation like the edge of a nickel scratching it. An impact will ding the paint and this cannot be avoided. The manufacturer recommends using Krylon Gloss Rough Tuff Enamel Spray paint to touch up any defects.
-- Etrailer Expert Sarah H - 07/03/2017

by:

Product shipped right away and arrived way sooner than I was anticipating.
Installation was easy - however the only thing that needs to be accounted for is the length of the shaft.
It made the trailer ride tipped back and had to do some modifications to make it work perfectly.
Construction of the product was good and it did exactly what I needed to accomplish
Would recommend .



by:

The product functioned well. We had a huge problem with bees living in the hitch area.



by:

This is a great product. I did a lot of research prior to choosing this model, but it has been very satisfactory in every category. E-trailer, was a great place to buy. Fast service and great follow up.



by:

Receved before expected delivery date, super easy install that took less than an hour. The hitch fit perfect on 1999 F250 short box even with 8" lift kit on the truck.



by:

The offset should have been about two inches longer. I can still get the front of the trailer into the back of the cab on a jcaknife. Works good??



by:

The folks at etrailer arranged faster shipping that advertised at no charge and the adapter arrived lots quicker than expected. The product is obviously better than the former adapter. Lots heaver and the ball receiver is easier to center above the ball.

Two EXCELLENT pieces of advice were included in the instructions. One was about bracing the hitch to prevent damage or coming loose from the trailer. The best advice regarded surging, or chucking. My previous adapter did both and neither a trailer manufacturer nor the RV people who sold and installed it could diagnose or fix the problem. This issue for me is important in that I have 3 fused vertebrae and stenosis.

As usual, RanchHand is leading the pack! I have a RanchHand "cowcatcher" bumper and it has done the job really well also.

Excellent product, Superb Advice!

Many Thanks!
