What Size Truck Do You Need to Tow a Cargo Trailer?
The sticker tow rating on your truck is only half the story. Here is how to figure out what your vehicle can really pull, and what size trailer fits it.
February 2, 2026 · 7 min read
Everybody wants a simple answer to what truck they need, but the honest answer is it depends on the loaded weight of the trailer, not just its size. A small SUV can handle a light single-axle cargo trailer, while a big tandem-axle enclosed trailer loaded with equipment might call for a three-quarter-ton truck. The good news is you can figure out exactly where you stand with a few numbers off your own vehicle.
The Numbers That Actually Matter
Tow ratings get thrown around, but there are a few ratings that decide what you can safely pull. You will find these in your owner's manual and on the sticker inside your driver's door jamb.
- Towing capacity is the max trailer weight your vehicle is rated to pull
- GVWR is the gross vehicle weight rating, the most your truck can weigh fully loaded with people and cargo
- Payload is how much weight you can put in the truck itself, including passengers, gear, and trailer tongue weight
- GCWR is the gross combined weight rating, the max your truck and loaded trailer can weigh together
- Tongue weight counts against your payload, so a heavy trailer eats into what you can carry in the truck
Why Payload Trips People Up
Here is the part most people miss. Your trailer's tongue weight, that 10 to 15 percent pressing down on the hitch, comes straight out of your truck's payload. Add a few passengers and a toolbox in the bed, and a half-ton truck can run out of payload long before it runs out of tow rating. Always check payload, not just the big towing number on the commercial.
A quick example makes it clear. Say your half-ton truck has a payload of 1,700 pounds. You load up 700 pounds of people and gear, which leaves 1,000 pounds for tongue weight. If you pull a 7,000 pound loaded trailer with tongue weight running 12 percent, that is 840 pounds on the hitch, and you are fine. Bump that trailer up to 9,000 pounds and your tongue weight jumps past 1,000 pounds, and now you are over payload even though the truck's tow rating might say 11,000. The tow number lied to you and the payload told the truth.
Matching Truck to Trailer Size
Cargo trailers generally break down into a few categories, and each one lines up pretty naturally with a class of tow vehicle. These are starting points, and you always confirm against your specific vehicle's ratings.
- 1Small single-axle trailers, roughly 5 by 8 or 6 by 10, loaded light, work behind many midsize SUVs and crossovers rated to tow
- 2Larger single-axle trailers around 6 by 12 pair well with a capable SUV or a half-ton truck
- 3Tandem-axle trailers like a 7 by 14 or 7 by 16 are best matched to a half-ton or three-quarter-ton truck
- 4Big enclosed haulers, 8.5 feet wide and long, loaded heavy, want a three-quarter-ton or one-ton truck
- 5When in doubt, size up on the truck rather than running your tow rating to the ragged edge
A truck that pulls a trailer easy is a truck that stops it easy too. Leave yourself margin and towing gets a lot less stressful.
Do Not Forget the Brakes
In Georgia and most states, once a trailer crosses a certain loaded weight, it is required to have its own brakes, and any tandem-axle cargo trailer worth owning will have electric brakes on at least one axle. That means your tow vehicle needs a brake controller, either built in from the factory or added aftermarket. A trailer that can slow itself down takes a huge load off your truck's brakes and shortens your stopping distance dramatically.
This matters even more when you think about how much heavier a loaded cargo trailer is than folks expect. An empty enclosed trailer is no lightweight to begin with, and once you fill it with tools, furniture, a side-by-side, or landscaping gear, the loaded weight climbs fast. Weigh your rig at a public scale if you can, because a real number beats a guess every time and tells you whether your truck is comfortable or overworked.
The Hitch Has to Match Too
Your truck's receiver hitch is rated by class, from a light Class I up to a heavy Class V. There is no point pulling a 7,000 pound loaded trailer with a hitch only rated for 3,500. Make sure your receiver, ball mount, and hitch ball are all rated at or above your loaded trailer weight, and that the ball size matches the trailer coupler. The whole chain is only as strong as its weakest piece.

Frequently Asked
How do I know how much my truck can tow?+
Check your owner's manual and the door jamb sticker for towing capacity, GVWR, payload, and GCWR. The loaded trailer weight must stay under your towing capacity, and tongue weight must fit within your remaining payload.
Can an SUV tow a cargo trailer?+
Many midsize and larger SUVs that are rated to tow can handle small single-axle cargo trailers. Larger tandem-axle enclosed trailers are better suited to a half-ton or heavier truck.
Does tongue weight count against my truck's payload?+
Yes. The tongue weight pressing down on your hitch comes directly out of your truck's payload, along with passengers and cargo. Ignoring this is why some trucks max out before hitting their tow rating.
Do I need a brake controller to tow a cargo trailer?+
If your trailer has electric brakes, which most tandem-axle cargo trailers do, you need a brake controller in your tow vehicle to operate them safely and legally.
What hitch class do I need for a cargo trailer?+
Match your receiver hitch, ball mount, and ball to at or above your loaded trailer weight. Small trailers may only need a Class II or III, while heavy enclosed haulers can require a Class IV or V.
