Finding the Correct Size Fifth-Wheel-to-Gooseneck Adapter
After backing the vehicle under the trailer, measure from the top of the ball in the truck bed to the base of the pin box on the trailer. This will indicate the height of the adapter that you need.
The included collar slides over your fifth-wheel trailer's king pin and is held in place with set screws. Additional, larger set screws that are mounted at the top of the coupler adapter then tighten onto the collar. Because this adapter is designed with an offset, the top lip of the adapter must also be bolted to the base of the pin box to ensure proper positioning.
This trailer coupler adapter features a simple, secure latching mechanism for safe, easy hookup with the hitch ball. The convenient extension handle grabs the sliding latch so that you can easily lock or unlock the coupler from outside the truck bed. Once the coupler is engaged, hook the handle through the hole in the sliding latch's track to ensure that it remains securely coupled. For extra safety, once the coupler is latched, you can replace the handle with a padlock (sold separately) to secure the trailer to the hitch ball during towing. Use a lock while your trailer is being stored to guard against towaway theft.
This coupler adapter is specially designed for use with truck beds that are between 6 feet and 8 feet in length. The offset allows your trailer to sit a bit farther back than it normally would so that you can make turns safely and with confidence. Supplying that extra space between your trailer and truck cab creates the clearance necessary for you to make tight turns without your trailer hitting your cab.

This hitch adapter is heavy duty. It's easy for two people to install in under an hour and all parts fit together well. The instructions were well written in English, which is the official language of our country (USA). The offset adapter works great with my 2011 Ram 2500 4x4 which sits higher due to oversized tires. My shipment was received two days after I ordered it without paying any expedited freight charges!
Thanks to the Convert-A-Ball and the fine folks at etrailer.com my days of listening to a clanging 5th wheel hitch are over. Thank you etrailer. 63540

The Fifth Wheel to Gooseneck Cushioned Adapter, item # CAB-C5GX1216, will now handle up to 4,000 pounds tongue weight.
If you need an adapter with more tongue weight capacity then the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter, item # AM3100, would be a good choice. This is a semi permanent installation and the capacity is up to 6,000 pounds tongue weight.

To determine the best 5th wheel trailer to gooseneck hitch adapter you will need, there are some measurements you can take in addition to knowing the pin weight and gross trailer weight of the trailer, loaded and ready to tow.
First, back your truck into position as if you were hooking up your fifth-wheel trailer, making sure that the truck and trailer are level. Then, measure from the pin plate (the bottom of the pin box) down to the top of the ball in the bed of your truck. This distance is view full answer...
I went out to the warehouse to measure the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter, # CAB-C5GX1216, and another adapter I think would be a better fit. The Convert-A-Ball portion that connects to the gooseneck ball measured 7-1/4 inches from side to side and 5-1/2 inches front to back.
I also measured the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter, # AM3139. At its widest point where it connects to the ball, the outside measurement is 5-1/2 inches. This would view full answer...

Measuring is going to be very important when determining the safest way to tow a fifth wheel trailer. The first step is to make sure that the trailer can be used with an adapter. Some 5th wheel manufactures state not to. Once you have verified you can use an adapter, you will need to measure for height needed by backing the truck under the trailer as if you were going to hook up.
Make sure both trailer and truck are on flat, level ground. Measure from the top of the ball to the bottom of the view full answer...
To determine if the Convert-A-Ball Gooseneck Coupler Adapter, # CAB-C5GX1216, will work with your 2011 Ford F-250 and your 2008 Flagstaff Fifth Wheel Trailer, you will need to measure from the top of your gooseneck ball to the bottom of the pin box. This will tell you what height adapter you will need. The Convert-A-Ball adapter is adjustable from 12 to 16 inches.

The setup that would give you the most clearance would be if you were to use a fifth wheel hitch and install a Sidewinder pin box. For a fifth wheel hitch I would recommend a Pro Series 5th Wheel Trailer Hitch - 20,000 lbs and a Reese Quick-Install Custom Base Rails and Installation Kit for 5th Wheel Trailer Hitches # PS30119, # RP50140-58.
A Sidewinder setup will give you the most clearance of all of the fifth wheel hitch setups. You will gain 22 inches of clearance by using a Sidewinder.

I am assuming since you are looking at a 5th wheel trailer to gooseneck hitch adapter that the trailer is a 5th wheel. For the greatest amount of offset, 8 inches, go with the Ranch Hitch, # AM3139. It is also rated the highest of any of the similar adapters; 24,000 pounds gross trailer weight and 6,000 pounds pin weight. You will also need the safety chains, # AM3109.
To calculate how much clearance you will have, measure from the center of the gooseneck ball to the back of the truck cab and view full answer...
To determine the clearance needed on your F-250 Super Duty 6-1/2 foot bed, you need to take the width of your fifth wheel 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.
For example, if your trailer measures 96 inches wide, take half (48 inches), then add 4 inches (52 inches). So if the measurement from the gooseneck hitch ball in the truck to the view full answer...
The offset gooseneck coupler adapters like part # CAB-C5GX1216 is designed to provide additional clearance between the fifth wheel trailer and the back of your truck bed. This item does not provide clearance to safely execute a 90 degree turn since the actual pivot point does not change.
If you were interested in an item that will allow you to make 90 degree turns without hitting your truck cab, then I would recommend looking into either a sliding fifth wheel hitch or a fixed fifth wheel hitc view full answer...
Hands down, the 5th wheel trailer to gooseneck trailer hitch that I recommend the most is the Ranch Hitch, # AM3139. It has the longest offset available at 8 inches. It is also rated for 6,000 pounds pin weight and 24,000 pounds gross trailer weight.
It is also height adjustable from 11-3/4 inches to 14-3/4 inches. To determine the height you need, back your truck into position as if you were hooking up your fifth-wheel trailer, making sure that the truck and trailer are level. Then measure view full answer...
Due to the short length of your truck box, Convert-A-Ball does not recommend using the Cushioned 5th Wheel-to-Gooseneck Adapter part # CAB-C5GX1216. The manufacturer does not recommend this item for use in truck beds shorter than 6 feet in length.
The problem with towing a fifth wheel with a short bed pickup is the clearance between the fifth wheel and the rear of the truck cab. There is a danger of the trailer loft striking the rear of the truck cab during turns.

Great question, I actually went out to the warehouse and pulled the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter w/ Offset, # CAB-C5GX1216, and did a short to show how it is adjusted, see link.
You will need to loosen the set screws at the front for 2 inches of adjustment and the set screws at the back allow for 2 more inches of adjustment. Make sure that the red line cannot be seen in either location when the adapter is adjusted to the correct position for your truck and trailer.

The Convert-A-Ball 5th-Wheel-to-Gooseneck Adapter w/ Offset, part # CAB-C5GX1216, is designed as one piece and to be used as a 5th-wheel-to-gooseneck adapter that requires an offset of 7-1/2 inches. It is not made to be taken apart. It would be used on trucks with shorter than 8-foot beds, but not shorter than 6-foot beds.
If you do not need the offset on your 2008 Ford F-150 you can use the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter, part # CAB-C5G. This is the same adapter a view full answer...

There is not an easy way to verify the tongue weight of a fifth wheel trailer if you do not already have the trailer. The best way to find the tongue weight of your fifth wheel trailer is to use a commercial scale like those at truck stops or at material supply centers. First you should weigh your tow vehicle without the trailer connected. Next, connect your trailer to your tow vehicle and drive it on the scale. The difference between the two weights is the tongue weight.

We carry a few different gooseneck-to-fifth-wheel coupler adapters that are adjustable greater than 15 inches, but we will first need to determine the compatibility of these adapters with your gooseneck hitch or fifth wheel pin box.
The Convert-A-Ball Coupler Adapter, # CAB-C5GX1216, that you referenced is adjustable up to 16 inches. Another option is the Hi-Rise Adapter, # 9480, which is essentially a fifth wheel hitch that works with a gooseneck hitch. This would require you to remove your view full answer...
First, the Convert-A-Ball adapter, # CAB-C5GX1216, is designed for towing a 5th wheel trailer if the truck has a gooseneck trailer hitch. If your truck has a gooseneck hitch using an adapter will make the trailer further back if there is an offset, however, since the pivot point of the trailer does not change, you will not get extra clearance to make tight turns, something that is a necessity for camp grounds and other places where space is limited.

The capacities of the truck for towing, tongue, payload, and others are listed in the owners manual. What you can do is take the gross vehicle weight rating as listed on the label in the door jamb and subtract the empty weight of the truck. What remains is how much the truck can carry including cargo and passengers.
The capacity in the truck bed is likely going to be high enough for most any 5th wheel trailer. On a 5th wheel trailer, the center of the king pin when connected to the trailer w view full answer...
