Best Rooftop Cargo Boxes for Road Trips and Gear Hauling

#1 · Best Overall

1. Yakima SkyBox NX 18 XLG

• Dimensions: 84"L x 36"W x 16.5"H
• Weight: 53 lb
• Material: Plastic

Best for: Long-ski adventure storage.

Why it ranks #1: Its 18-cubic-foot capacity, dual-sided access, included SKS locks, and stated fit for skis or snowboards up to 195 cm make it versatile for trips.

Compatibility with skis and snowboards up to 195 centimeters gives the Yakima SkyBox NX 18 XLG a clear role for winter-trip gear. Its 18 cubic feet of storage, dual-sided opening, and full-metal locking handle combine substantial capacity with access from either side of the vehicle.

The 84-by-36-by-16.5-inch exterior and stated 18-cubic-foot capacity give shoppers a basis for checking roof space and packing plans. Its listed fit for skis and snowboards up to 195 centimeters makes it especially relevant to longer winter equipment. Dual-sided access lets users load from either side, while the full-metal handle locks gear inside and the box to the vehicle. An unobstructed flattened floor offers a more continuous interior surface for arranging cargo.

Skip it if you carry skis no longer than 175 cm and want a shorter Yakima; the SkyBox NX 16 LG measures 75.5 inches long.

Choose the SkyBox NX 18 XLG for campers or winter-sport travelers carrying equipment up to 195 centimeters and needing two-sided access. Its 84-inch length is a significant fit boundary, so assess available roof space first.

#2 · Best Rear Opening

2. SportRack Vista XL

• Material: Plastic

Best for: Rear-access family packing.

Why it ranks #2: It offers 18 cubic feet, rear access away from traffic, tool-free mounting hardware, and stated compatibility with several rack types.

Rear opening is the Vista XL’s defining advantage: it lets you reach stored gear from the back of the vehicle, away from passing traffic. Its 18-cubic-foot interior adds substantial rooftop storage, while UV-resistant ABS construction and included locking hardware support regular travel use.

The 18-cubic-foot capacity gives road-trip gear a separate home above the cabin, helping preserve passenger space. Rear access keeps loading and retrieval on the vehicle’s back side rather than beside traffic. Tool-free mounting hardware simplifies installing or removing the box, and the included lock secures both contents and the box to the rack. It fits SportRack systems, square and round bars, and most factory racks; check the fit guide and crossbar spacing before installation.

Skip it if you need dual-side access; the Yakima SkyBox NX 18 XLG opens from either side and fits skis up to 195 cm.

Choose the Vista XL for road trips when rear-side loading and 18 cubic feet of extra space matter. Its fit spans several rack styles, but verify your rack and the stated crossbar-spacing range before mounting.

• Dimensions: 54.3"L x 31.5"W x 13.4"H
• Weight: 36 lb

Best for: Compact two-sided access.

Why it ranks #3: This 12-cubic-foot ABS box opens from either side and includes a lock; its 54.3-inch length suits buyers who need a shorter carrier.

Dual-sided opening gives this 12-cubic-foot Garvee box a useful access advantage, letting users reach luggage from either side of the vehicle. Its ABS shell is described as waterproof and UV-resistant, and the included lock secures both stored contents and the carrier to the vehicle.

At 54.3 by 31.5 by 13.4 inches, this shell offers dimensions shoppers can compare against roof space and planned cargo, alongside its listed 12-cubic-foot capacity. Dual-side access makes loading possible from either side, but the listing cautions against opening both sides simultaneously. The ABS construction is described as waterproof and UV-resistant, and included locking provisions secure the contents and box. Strong arms are also specified, supporting the opening system during use.

Skip it if you need a larger stated volume; the Maxsa Innovations 21-cubic-foot carrier lists substantially more storage capacity.

This Garvee suits travelers wanting a compact 12-cubic-foot box with two-sided access and a lock. Follow the stated caution not to open both sides simultaneously, and compare its 54.3-inch length with your cargo.

• Dimensions: 62.2"L x 31.5"W x 13.4"H
• Weight: 44.8 lb

Best for: Mid-size dual-side cargo.

Why it ranks #4: The listed 14-cubic-foot version includes crossbar dimensions: 20.5 to 30.3 inches spacing, with bars 1.1 to 3.3 inches wide.

This 62.2-inch GarveeTech shell pairs dual-side opening with a stated 14-cubic-foot configuration, providing room for rooftop luggage and access from either side. Its ABS construction is described as waterproof and UV-resistant, making weather protection a central part of its travel-storage proposition.

The 62.2-by-31.5-by-13.4-inch dimensions help buyers judge whether the shell can sit on their roof and accommodate their cargo; its listed configuration is 14 cubic feet. Dual-side opening gives a choice of loading side, while the ABS shell is described as waterproof and UV-resistant. For the 14-cubic-foot version, the stated crossbar spacing is 20.5 to 30.3 inches, with bar width of 1.1 to 3.3 inches and height of 0.7 to 1.5 inches, useful checks before installation.

Skip it if you need a box with a stated lock and included keys; the Garvee 12-cubic-foot carrier lists both.

This GarveeTech model suits travelers who want dual-side access, weather-resistant shell material, and the listed 14-cubic-foot volume. Its crossbar measurements are a firm fit consideration, so compare them with your rack before installation.

#5 · Highest Capacity

5. Maxsa Innovations 26.5-Cubic-Foot Box

• Dimensions: 81.1"L x 32.28"W x 13.39"H
• Weight: 46.3 lb

Best for: Extra-long gear storage.

Why it ranks #5: Its listed 26.5-cubic-foot capacity is the largest in this selection, while the 81.1-inch length makes roof-space checks important.

The stated 26.5-cubic-foot capacity distinguishes this Maxsa Innovations carrier for shoppers seeking a particularly large rooftop storage claim. Its 81.1-inch length gives the shell a long profile, while the listed locking system and two keys address access security for stored travel gear.

At 81.1 inches long, 32.28 inches wide, and 13.39 inches high, this shell’s dimensions help shoppers assess whether its footprint suits their vehicle and cargo. The 26.5-cubic-foot capacity offers a sizeable stated storage volume, and Maxsa lists a locking system with two keys plus robust straps. Included installation components and clear instructions are described as supporting setup. The provided specifications do not state rack compatibility or a load limit, so confirm those needs before selecting it.

Skip it if you need a stated rack fit or load rating; SportRack Vista XL lists supported rack types and a 100-pound capacity.

This is an option for travelers prioritizing the listed 26.5-cubic-foot volume and long shell dimensions. Its stated specifications leave rack compatibility and load capacity unresolved, so buyers needing those limits documented should look elsewhere.

#6

6. Yakima SkyBox NX 16 LG

• Dimensions: 75.5"L x 35"W x 16"H
• Weight: 46 lb
• Material: Plastic

Best for: Shorter Yakima ski storage.

Why it ranks #6: It has dual-sided access, included SKS locks, and a 75.5-inch length; the title lists 16 cubic feet and ski or snowboard fit to 175 cm.

A 75.5-inch listed length makes the Yakima SkyBox NX 16 LG a shorter option than the brand’s 18 XLG, while its stated ski fit reaches 175 centimeters. Dual-sided access and a full-metal locking handle add convenient loading and security features.

The 75.5-by-35-by-16-inch exterior gives buyers dimensions for assessing roof space, and the product title identifies a 16-cubic-foot version. Its stated fit for skis and snowboards up to 175 centimeters addresses winter gear, while dual-sided opening allows loading from either side. The full-metal handle locks both cargo and box to the vehicle. An unobstructed flattened floor supports arranging items across the interior, though the supplied features also describe 18 cubic feet, so verify the capacity detail before purchase.

Skip it if you carry skis longer than 175 cm; the Yakima SkyBox NX 18 XLG lists compatibility up to 195 cm.

Consider this Yakima for winter travelers whose skis fit within 175 centimeters and who want dual-side loading in a 75.5-inch shell. Capacity details conflict between title and features, so resolve that point before relying on volume.

7. GarveeTech 12-Cubic-Foot Box

• Dimensions: 54.3"L x 31.5"W x 13.4"H
• Weight: 39 lb
• Material: Acrylonitrile Butadiene Styrene (ABS)

Best for: Weather-conscious dual-side loading.

Why it ranks #7: This 12-cubic-foot ABS carrier has dual-side opening, stated waterproof and UV-resistant construction, and a listed 165-pound weight capacity.

Dual-side opening is the most practical feature of this GarveeTech box, letting users access luggage from either side of the vehicle. Its 12-cubic-foot capacity, waterproof and UV-resistant ABS shell, and secure straps target road-trip storage where weather protection and loading access both matter.

The 54.3-by-31.5-by-13.4-inch shell provides a compact footprint to compare with rooftop space, while the stated 12-cubic-foot volume adds room for luggage. Dual-side opening gives access from either side, which can simplify reaching cargo when one side is blocked. ABS construction is described as waterproof and UV-resistant, supporting protection from weather exposure. The listing also states a 165-pound weight capacity and includes secure straps and keys, useful details for planning a load and securing it.

Skip it if you carry skis up to 195 cm; the Yakima SkyBox NX 18 XLG explicitly lists that length compatibility.

Choose this box for road-trip luggage when two-sided access and weather-resistant ABS construction suit your routine. Its 54.3-inch length is a boundary for long cargo, so compare item dimensions against the shell before packing.

#8

8. Maxsa Innovations 21-Cubic-Foot Box

• Dimensions: 68.11"L x 31.89"W x 14.57"H
• Weight: 41.9 lb

Best for: Lockable 21-cubic-foot storage.

Why it ranks #8: The 21-cubic-foot hard shell includes a locking system and two keys, though the supplied details do not specify crossbar fit measurements.

A stated 21-cubic-foot capacity is the central reason to consider this Maxsa Innovations hard-shell carrier: it offers a substantial space claim for moving travel gear onto the roof. Its locking system, two keys, and robust straps provide the listed security provisions for trips.

The 68.11-by-31.89-by-14.57-inch shell gives buyers concrete dimensions to compare with rooftop space and the gear they plan to carry. Maxsa lists a locking system with two keys and robust straps, so the box has specified provisions for securing stored items during travel. Installation components and clear instructions are also described as included, a useful setup aid. The supplied information does not state rack compatibility or a load limit, so those remain important selection checks.

Skip it if you need documented fit details before choosing; SportRack Vista XL lists compatibility with square, round, and most factory racks.

Consider this carrier if the stated 21-cubic-foot capacity and keyed locking system match your travel-storage priorities. Buyers who need a specified load rating or rack fit should choose only after those details are established.

#9

9. DNA Motoring 11-Cubic-Foot Box

• Dimensions: 53"L x 34"W x 15"H
• Material: ABS Plastic

Best for: Crossbar-ready bulky-item storage.

Why it ranks #9: It supplies 11 cubic feet and a stated 110-pound capacity, with mounting brackets and keys included; it fits vehicles with crossbars only.

An opening width of up to 14 inches is the practical differentiator of this DNA Motoring carrier, giving bulky items a stated loading clearance. The ABS box adds 11 cubic feet of storage, accepts vehicles with crossbars, and lists a 110-pound maximum when weight is evenly distributed.

The 53-by-34-by-15-inch shell offers a defined footprint for checking roof and cargo fit, while the stated 11-cubic-foot capacity provides extra storage. Its opening reaches up to 14 inches wide, which can help with bulkier items that need more clearance. ABS construction is described as rugged and impact-resistant. The box is specified for crossbar-equipped vehicles and no-tool installation, and its 110-pound maximum applies when cargo weight is evenly distributed, an important loading constraint.

Skip it if you need two-sided access; the Yakima SkyBox NX 16 LG lists dual-sided opening for loading from either side.

This DNA Motoring box fits crossbar-equipped vehicles and buyers needing an 11-cubic-foot shell with a wider opening for bulky cargo. Keep loads within 110 pounds and distribute weight evenly; its dimensions also warrant a roof-space check.

#10

10. D SOLUTIONS Hard Shell Box

• Dimensions: 53"L x 34"W x 15"H
• Weight: 50.3 lb
• Material: ABS Plastic

Best for: Tool-free crossbar installation.

Why it ranks #10: Its 53-by-34-by-15-inch ABS shell and stated 110-pound capacity suit basic cargo use, but supplied facts include unrelated vehicle-product details.

No-tool assembly and installation are the headline convenience here, provided your vehicle already has crossbars. The D SOLUTIONS ABS shell measures 53 by 34 by 15 inches and is listed with a 110-pound load capacity, pairing straightforward setup with defined cargo limits.

The stated crossbar-only compatibility makes the first decision simple: this box is for vehicles equipped with crossbars. No-tool assembly and installation can reduce setup steps, while the 53-by-34-by-15-inch dimensions help assess cargo and roof fit. ABS construction is described as durable and intended to protect contents from inclement weather. Its listed 110-pound capacity supplies a clear ceiling for load planning; the product information does not provide a cargo-volume figure, so buyers should compare actual item dimensions instead.

Skip it if you lack roof crossbars; the SportRack Vista XL lists compatibility with most factory racks, square bars, and round bars.

Consider this carrier if your vehicle has crossbars and you value no-tool installation with a stated 110-pound limit. Its dimensions are provided, but no cargo-volume figure is listed, so judge capacity by the items you carry.
