How to Measure Truck Bed Clearance
Do this first. Short beds and crew cabs need clearance math before you buy a hitch head or gooseneck ball.

Choosing between a gooseneck and a fifth-wheel hitch in Canada is really a truck-bed decision, not an SUV bumper decision. Both setups live in the bed over or near the rear axle. A fifth-wheel hitch uses a head that locks onto a kingpin, which is the usual setup for recreational fifth-wheel trailers. A gooseneck uses a ball in the bed for many stock and utility trailers. Here is when each setup fits, with CURT puck, head and rail kits we stock, plus free shipping anywhere in Canada.

Start with the trailer coupler you already own or plan to buy. Kingpin trailers want a fifth-wheel head and matching legs or rails. Gooseneck couplers want a bed ball and a puck or rail system the truck supports. Factory puck prep on many GM, Ford, Ram, and Nissan trucks simplifies either one when the live kit lists your years. Short beds need a slider or roller. If you only tow a conventional bumper-pull trailer, stay on a rear receiver and skip bed hardware.
Kingpin versus gooseneck ball decides the family.
Each kit lists which beds it fits.
Sliders and rollers exist because cab contact is real.
Do not force bed hardware onto the wrong job.

| Topic | What we tell shoppers |
|---|---|
| Fifth wheel | Kingpin trailers pair with a head plus legs or rails in the bed. |
| Gooseneck | Gooseneck couplers pair with a bed ball and puck or rail prep. |
| Truck realities | Bed length, puck prep, and payload still decide the job. |
| Stay conventional | Bumper-pull trailers belong on a rear receiver, not bed hardware. |




In short: name the coupler first, match puck or rail prep on the truck, respect short-bed clearance, and keep bumper-pull trailers on a conventional receiver.
