1. Thule Sidekick: Top Pick
The Thule Sidekick is a top choice for a trunk-mounted cargo carrier. In our evaluation, it stands out for its strong construction and weather-sealed design. Owner feedback consistently praises its ability to keep contents dry even in heavy rain. The soft shell is made from durable, UV-resistant fabric, and the mounting straps are secure without scratching the paint. However, it requires a trunk with a clean, flat surface; spoilers or unusual contours may prevent a proper fit.
If you need a carrier for occasional use and have a standard sedan or hatchback, this is a solid investment. But if you have a vehicle with a prominent spoiler or a very small trunk, you might want to consider a hitch-mounted option. Also, the 110 lb limit means you cannot overload it with heavy items like camping gear.
- Weatherproof fabric and zippers keep gear dry.
- Folds flat when not in use for easy storage.
- Integrated tie-down loops and reflective accents for safety.
Pros: Excellent build quality and weather resistance.; Easy to install and remove without tools.
Cons: Not compatible with all trunk shapes, especially those with spoilers.
2. Yakima SkyBox Pro 16: Runner Up
The Yakima SkyBox Pro 16 is a hard-shell roof box, but it can be mounted on a hitch-mounted carrier with an adapter. In our research, it offers exceptional security and weather protection. The dual-side opening is a convenience that owners love. However, it is heavy and not suitable for those who need to frequently mount and unmount it. Also, it requires crossbars, adding to the overall cost.
This carrier is ideal for long trips where you need to carry bulky but relatively light items like luggage or camping gear. Skip it if you have a small car with a low roof or if you prefer a trunk-mounted solution for easier access. The weight can be a deal-breaker for some users.
- Hard shell provides superior protection and security.
- Dual-side opening for easy access from either side.
- Aerodynamic design reduces wind noise and drag.
Pros: Very secure with built-in locks.; Durable and long-lasting construction.
Cons: Heavy and cumbersome to install and remove alone.; Requires roof crossbars (not included).
3. Curt 18151 Class 1 Trailer Hitch Receiver: Best Hitch Receiver
The Curt 18151 is a popular choice for adding a hitch receiver to a car. In our evaluation, it offers a good balance of strength and value. Owner feedback indicates it is relatively easy to install on most cars, though some require minor modifications. The 200 lb tongue weight is sufficient for most cargo carriers and bike racks.
However, this is not a carrier itself but a hitch receiver. You will need to purchase a cargo carrier basket or platform separately. If your car is not listed as compatible, or if you prefer a trunk-mounted solution, this is not for you. Also, installation may be challenging for those without mechanical skills.
- Custom fit for many car models (check compatibility).
- Corrosion-resistant black powder coat finish.
- Easy bolt-on installation with no drilling required.
Pros: Affordable and widely compatible.; Solid construction with a good warranty.
Cons: Installation can be tricky on some vehicles, requiring removal of bumper covers.; Not all cars are compatible; check before buying.
4. Allen Sports 302SW Deluxe Trunk Mounted Carrier: Budget Friendly
The Allen Sports 302SW is a budget-friendly trunk carrier that gets the job done for light use. In our research, it offers decent capacity for the price, but the waterproofing is not as reliable as higher-end models. Owner reviews mention that the carrier can leak in prolonged downpours. The straps are adequate but may require re-tightening during long trips.
This carrier is suitable for occasional short trips or for carrying dry items like clothing. If you need to transport electronics or items that must stay dry, invest in a more weather-resistant model. Also, the 100 lb limit means you cannot overload it, but that is typical for this category.
- Very affordable compared to other trunk carriers.
- Folds down for storage when not in use.
- Reflective strips for added visibility at night.
Pros: Great value for the price.; Lightweight and easy to install.
Cons: Not fully waterproof; leaks can occur in heavy rain.; Straps may loosen over time; need periodic tightening.
5. Smittybilt 2785 SRC Classic Spare Tire Carrier: Off-Road Choice
The Smittybilt 2785 is a specialized carrier for off-road enthusiasts who need to carry a spare tire or extra gear. In our evaluation, its steel construction is extremely durable, but it is heavy and difficult to install. Owner feedback indicates that it works best on Jeeps and trucks with a swing-out tire carrier. It can be adapted to other vehicles, but the process is not straightforward.
This carrier is not for everyone. If you drive a standard car, this is likely not compatible. It is designed for off-road vehicles and those who need a solid solution for a spare tire. Skip it if you want a simple trunk or hitch carrier for everyday use.
- Heavy-duty steel construction for rugged use.
- Designed to mount on spare tire or rear bumper.
- Includes a locking pin for security.
Pros: Very durable and can handle rough terrain.; Does not block rear view like trunk carriers.
Cons: Installation is complex and may require drilling.; Not compatible with all spare tire sizes or vehicles.
6. Keeper 85018 Trunk Cargo Carrier: Compact Pick
The Keeper 85018 is a compact trunk carrier that fits smaller vehicles well. In our research, it offers adequate space for a weekend trip. However, owner reviews note that the straps may need frequent adjustment, and the fabric is not fully waterproof. It is best used in dry weather or with a separate waterproof cover.
This carrier is a decent choice if you drive a small car and need an occasional extra cargo space. But if you frequently travel in rain or on rough roads, consider a more secure option. The 100 lb limit is typical, but the lack of security features may be a concern.
- Compact design fits smaller cars well.
- UV-resistant fabric prevents sun damage.
- Adjustable straps for a secure fit.
Pros: Good for compact cars with limited trunk space.; Easy to store when not in use.
Cons: Straps can loosen on bumpy roads.; Not as weather-resistant as some competitors.
7. Rola 59504 V-Tech Cargo Carrier: Hitch Basket Alternative
The Rola 59504 is a hitch-mounted cargo basket that offers excellent carrying capacity. In our evaluation, it is built to handle heavy loads, but it requires a hitch receiver. Owner feedback highlights its durability, but some find it cumbersome to access the trunk. The basket does not have a cover, so items are exposed to weather unless you add a cargo bag or net.
This carrier is ideal for those who already have a hitch and need to transport large, heavy items like camping gear or sports equipment. Skip it if you need weather protection or if you frequently need to open your trunk without unloading the carrier.
- Large capacity for bulky items like coolers.
- Folds up when not in use for storage.
- Includes anti-rattle hitch pin.
Pros: Very strong and can carry heavy loads.; Flexible for different types of cargo.
Cons: Requires a hitch receiver (not included).; Can be difficult to access trunk with carrier installed.
Frequently Asked Questions
What is the weight limit for a rear car carrier?
Weight limits vary by carrier type and mounting method. Trunk-mounted carriers typically have a limit of 100-110 lbs, while hitch-mounted carriers can handle up to 500 lbs depending on the hitch class. Always check your vehicle’s hitch rating and the carrier’s specifications.
Will a rear carrier block my license plate or taillights?
Yes, many rear carriers can obstruct the license plate and taillights. It is important to use a license plate relocation kit or add auxiliary lights to remain legal and safe. Some carriers include a light bar, but you may need to purchase separately.
Can I use a trunk carrier with a spoiler?
It depends on the carrier and the spoiler design. Many trunk carriers use straps that hook onto the trunk lid, which may interfere with spoilers. Check the carrier’s compatibility list or consider a hitch-mounted option if your vehicle has a spoiler.
How do I prevent my cargo carrier from swaying?
For trunk carriers, ensure straps are tight and use anti-sway straps if available. For hitch carriers, use an anti-rattle hitch pin and a stabilizer strap that attaches to the vehicle’s bumper. Proper loading with heavier items low and centered also reduces sway.
Are soft shell carriers as secure as hard shell ones?
Soft shell carriers are generally less secure because they are made of fabric and zippers, which can be cut. Hard shell carriers offer better protection against theft and weather. However, soft shell carriers are lighter and easier to store. Choose based on your security needs.
Our Verdict
After researching and comparing the top carriers for the back of a car, the Thule Sidekick earns our top pick for its excellent build quality, weather resistance, and ease of use for trunk-mounted needs. For a hitch-mounted solution, the Yakima SkyBox Pro 16 stands out as a runner up for its security and durability, though it requires crossbars and is heavier. Consider your vehicle type, storage needs, and budget when making your choice.
