Does your trailer have a rotational pinbox?
Brands like Turning Point or Sidewinder. These rotate to give your truck cab clearance during tight turns.
Good to know: With a rotational pinbox, you can use a fixed hitch instead of a slider. Gooseneck Fifth Wheel adapters won't work with rotational pinboxes.
Do you have a B&W Turnoverball system?
B&W's Turnoverball is a specific gooseneck system. If you have one, their Companion hitch drops right in.

Demco
Demco Recon 21K Flat Deck Fifth Wheel Hitch (Recessed Gooseneck Ball)
This Recon 21K Flat Deck mounts a fifth wheel onto a recessed gooseneck ball, keeping the bed flat when the hitch is off. Easy to drop onto an existing ball at a fair price, though it's fixed-head only and the tow is solid without being smooth.
Demco
Demco Recon 21K Gooseneck Ball-Mount Fifth Wheel Hitch
The Recon 21K Gooseneck Ball-Mount lets you run a fifth wheel off any existing 2-5/16in gooseneck ball, so it drops on without a rail or puck install. Versatile and good value, but it's a fixed head with no cushioning and articulation is just adequate.
PullRite
20K SuperLite
$1,015
The 20K SuperLite is a lighter gooseneck-ball fifth-wheel head that drops onto an existing ball for a 20,000-lb tow with no rails required. Easier to handle than the Super 5th and a bit cheaper, with only a slight give in ride smoothness.
Demco
Demco Recon Stealth 20K Folding Gooseneck Ball-Mount Fifth Wheel Hitch
The Recon Stealth 20K is a folding gooseneck ball-mount that sets a fifth wheel onto any 2-5/16in ball and folds down for a clear bed. Handy and well-priced for ball-mount towing, but the 20K fixed head trades a bit of capacity and ride polish versus dedicated puck units.
Good to know
The adapter adds some height. Check clearance between your truck cab and trailer front.
Pick your pinbox
Replaces your trailer's factory pinbox with a gooseneck-compatible one.

Reese Goose Box
2 versions — picked by your trailer's pin box and weight
The Gen 3 Goose Box (20K) swaps your trailer's pin box for an air-ride gooseneck coupler, freeing up the truck bed entirely. The air cushion smooths the ride and cuts chucking, making it the standout pin-box conversion if you'd rather pull a fiver off a gooseneck ball.

B&W
20K Companion Slider
$1,599
A sliding 20K Companion that mounts on an existing gooseneck ball, giving short-bed trucks both fifth-wheel capability and turning clearance. The manual slide is the trade-off, but the cushioned head tows quiet and smooth.
B&W
20K Companion
$1,099
This 20K Companion head drops onto an existing gooseneck ball, turning a gooseneck truck into a fifth-wheel hauler without bed rails. You get the cushioned, fully-articulating Companion ride on top of a Turnoverball setup.
