How to Choose the Right Size Cargo Trailer for Your Hauling Needs
When it comes to hauling your gear, tools, or toys, choosing the right cargo trailer can feel like a bit of a guessing game. Do you go small and easy to tow? Big and ready for anything? Will everything actually fit… or will you be playing trailer Tetris every weekend?
These are all common questions we hear from folks just getting into the world of cargo trailers—and don’t worry, you’re not alone! At South Thompson RV in Kamloops, BC, we’re here to break it all down and help you find the perfect trailer size for your lifestyle.
Cargo Trailer Basics
Size Matters (But So Does Purpose!)
Before you start comparing sizes, the first thing to think about is what you’ll actually be hauling.
Are you transporting tools for work? Moving furniture? Packing up dirt bikes or ATVs for a weekend trip? The type of cargo you carry will play a big role in determining the size you need.
Cargo trailers typically range from compact 4x6 models all the way up to larger 8.5x20+ units. Smaller trailers are great for light loads and easy towing, while larger ones give you the flexibility to carry more, but they also require a bit more planning when it comes to storage and maneuvering.
A good rule of thumb? It’s better to have a little extra space than not enough. Just don’t go so big that it becomes a hassle to tow!
Weight and Towing Capacity
Now that you’ve got size in mind, let’s talk about weight.
Just like with travel trailers, your vehicle’s towing capacity is key. Most smaller SUVs can handle lightweight cargo trailers, typically in the 2,000–4,000 lb range. Mid-sized trucks and larger SUVs can tow more, while full-sized trucks give you the most flexibility, especially for heavier loads.
You’ll also want to factor in the weight of everything you’re hauling. Tools, equipment, or recreational gear can add up quickly, so always leave yourself a bit of a buffer.
When in doubt, check your vehicle specs and match them carefully with your trailer’s weight rating. Your future self (and your brakes) will thank you!
Common Cargo Trailer Sizes and Uses
Not sure where to start? Here’s a quick breakdown of popular cargo trailer sizes and what they’re best for:
- 4x6 or 5x8 – Great for light hauling like small furniture, tools, or yard equipment. Easy to tow and store.
- 6x10 or 6x12 – A solid all-around option. Perfect for small business use or weekend gear.
- 7x14 or 7x16 – Ideal for ATVs, motorcycles, or larger loads. A popular choice for recreational use.
- 8.5x16+ – Best for serious hauling, multiple vehicles, or commercial use. Plenty of space, but requires a capable tow vehicle.
Think about how often you’ll use the trailer and what you’ll use it for most. That will help narrow things down quickly.
Height, Door Style, and Interior Space
It’s not just about length and width—height matters too.
If you plan on walking inside your trailer or loading taller equipment, consider a model with extra interior height. Ramp doors are great for loading vehicles and heavy gear, while barn doors might work better for general cargo access.
You’ll also want to think about interior layout. Shelving, tie-down points, and storage solutions can make a huge difference in how functional your trailer is day-to-day.
Ease of Towing and Maneuvering
Let’s be real—bigger isn’t always easier.
A larger cargo trailer gives you more room, but it also takes more practice to tow and park. If you’re new to towing, starting with a smaller or mid-sized trailer can make the learning curve a lot smoother.
Take your time, go slow, and don’t be afraid to practice in an empty parking lot. Trust us—it’s a lot less stressful than figuring it out in a crowded campsite or job site!
The Truck vs. SUV Question (Sound Familiar?)
Just like with RVs, choosing between a truck or SUV comes down to capability.
Trucks generally offer higher towing capacity and more flexibility, making them a great match for larger cargo trailers. SUVs can absolutely get the job done too—especially for smaller trailers—but you’ll want to stay within their limits
At the end of the day, it’s all about finding the right balance between your vehicle, your trailer, and your comfort level behind the wheel.
