Not all hitches are equal — and using the wrong type for your trailer can compromise safety, handling, and your truck’s suspension. Here’s a guide to the main hitch types and when to use each.
Hitch Classes
Class I & II: Rated to 3,500 lbs and 3,500 lbs respectively. For light trailers (small boats, small utility trailers). Usually 1.25" or 2" receiver.
Class III: 2" receiver, up to 8,000 lbs. The standard on most 1/2-ton trucks.
Class IV: 2" receiver, 10,000–12,000 lbs. Common on HD 1/2-ton and light 3/4-ton.
Class V: 2.5" receiver, 16,000+ lbs. Found on heavy-duty trucks; used with gooseneck/5th wheel adapters.
Conventional Ball Mount
The most common setup. A ball mount with a 1⅞", 2", or 2 5/16" ball sits in the receiver.
Best for: Trailers up to 8,000 lbs gross with no extreme tongue weight.
Important: The ball height must put your hitch point level or within 2–4" of the trailer coupler height when loaded. A drop/rise ball mount corrects height mismatch.
Weight Distribution Hitch (WD)
Required for trailers where tongue weight exceeds 10% of your truck’s curb weight or where handling is affected under load. Distributes tongue weight to all four wheels.
The Camco Eaz-Lift ReCurve R3 Weight Distribution Hitch handles up to 14,000 lbs gross and works with most 1/2-ton and 3/4-ton trucks.
When to use: Any trailer over ~6,000 lbs GVWR that creates noticeable rear sag in your truck.
Note: WD hitches require a round bar setup and are NOT compatible with sway control on gooseneck/5th wheel setups.
Fifth Wheel
A fifth wheel hitch mounts in the truck bed and connects to a kingpin on the front of a fifth wheel trailer (usually large RVs or enclosed cargo trailers).
Capacity: Typically 16,000–25,000 lbs depending on the hitch rating.
The Reese 20,000 lb 5th Wheel Hitch is a solid option for HD 2500/3500 applications.
Pros: Better stability than ball-mount for heavy loads; lower center of gravity
Cons: Requires bed space permanently (or a slider for short-bed trucks)
Gooseneck
Similar to fifth wheel in terms of weight capacity, but uses a ball in the center of the truck bed. Popular for livestock trailers, flatbeds, and equipment trailers.
Rated to: Up to 30,000+ lbs on properly equipped 3500 trucks
Requires: Gooseneck hitch kit installed in the truck bed
Anti-Sway Devices
If your trailer sways, use a sway control bar (on WD hitch setups) or upgrade to a trailer with a proper integrated sway control system. The correct trailer weight distribution setup eliminates most sway.
