Car roof cargo boxes add enclosed storage for road trips, but the right choice depends on your vehicle, roof-rack setup, and what you plan to carry. I rank the Thule Pulse 2 M as the best overall pick for its practical 14-cubic-foot capacity and dual-side access. The Maxsa Innovations 17-cubic-foot box is a standout when extra room matters most, while the SportRack Vista XL suits buyers who prefer rear access. The main tradeoffs are storage capacity versus vehicle fit, loading convenience versus box placement, and a hard shell’s protection versus the added roof bulk. Read on for the full breakdown, selection criteria, and fit questions to answer before buying.

Key Takeaways
The Thule Pulse 2 M offers the strongest all-around balance in this lineup: 14 cubic feet and dual-side opening without choosing the largest box.
The Maxsa Innovations has the largest listed capacity at 17 cubic feet, making it the clearest choice for buyers who prioritize space over a more compact footprint.
Dual-side access appears on several GarveeTech and Garvee models as well as the Thule, but capacity varies from 12 to 14 cubic feet; access style alone does not determine usable room.
The SportRack Vista XL’s rear-opening design differs from the lineup’s dual-side options, so its appeal depends on whether rear access better suits the vehicle and parking setup.
Several options are listed at 11 to 12 cubic feet, including models from DNA MOTORING, D SOLUTIONS, GarveeTech, and Garvee; compare exact dimensions, mounting compatibility, and opening direction before treating them as interchangeable.

More Details on Our Top Picks
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 cu ft, Dual-Side Opening
I’d rank the Thule Pulse 2 M first for buyers who want a useful balance of capacity, loading access, and a more guided installation. Its 400-liter (14 cu ft) interior holds road-trip luggage and gear, while the 75 kg load limit gives more capacity by weight than the Maxsa Innovations box’s 165 lb rating. The tool-free mount with a torque indicator and closure confirmation also offers clearer installation feedback than the strap-mount approach on that Maxsa model. Dual-side access helps when another vehicle or a wall blocks one side, and its forward-positioned design is intended to preserve trunk access. The tradeoff is that buyers still need compatible roof hardware, and this is not the roundup’s largest option: the Maxsa offers 17 cu ft. I’d choose Thule for a balanced, feature-led pick rather than maximum volume.
Pros:- Dual-side opening makes loading easier when access on one side is blocked.
- Tool-free mounting system includes a torque indicator and closure confirmation.
- 400 liters (14 cu ft) of capacity with a 75 kg load limit.
- Forward-positioned design allows trunk access.
Cons:- Requires a compatible vehicle roof and mounting setup.
- Offers less volume than the 17 cu ft Maxsa Innovations box.
Best for: Drivers who want a mid-size roof box with dual-side access and guided, tool-free mounting, and whose vehicle has compatible roof hardware.
Not ideal for: Travelers who need the most storage in this group or cannot confirm that their roof and mounting setup are compatible.
- Brand:Thule
- Model:Pulse 2 M
- Capacity:400 liters (14 cu ft)
- Load capacity:75 kg
- Material:ASA-ABS plastic
- Mounting:Roof mount; tool-free mounting system
- Opening:Dual-side
- Fit:Universal fit
- Warranty:Limited lifetime
Our verdict“Choose the Thule Pulse 2 M for a balanced 14 cu ft box with guided mounting, provided your vehicle setup is compatible.”
Maxsa Innovations Hard-Shell Rooftop Cargo Box, 17 cu ft
If fitting the most gear is the priority, I’d look at the Maxsa Innovations 17 cu ft box before the smaller models here. It has more listed volume than the Thule Pulse 2 M and either GarveeTech box, making it a better match for bulky luggage or multiple travelers’ gear. Its dual-side opening and included straps and keyed lock add practical access and basic cargo security. The ABS shell is described as waterproof, a useful distinction from the DNA MOTORING box, which is explicitly not water resistant. Capacity comes with tradeoffs: the Maxsa is 55.12 inches long and 35.04 inches wide, weighs 35.3 pounds, and uses strap mounting rather than the Thule’s tool-free system with installation feedback. Buyers need to confirm rack compatibility and account for the box’s size before choosing it over a more compact option.
Pros:- 17 cu ft capacity is the largest listed among these five products.
- Dual-side opening provides access from either side of the vehicle.
- Waterproof ABS shell is suited to carrying gear in wet conditions.
- Includes mounting straps and a keyed lock with two keys.
Cons:- Large dimensions may not suit every vehicle roof or parking setup.
- Uses strap mounting rather than the Thule Pulse 2 M’s torque-indicator mounting system.
- Roof rack compatibility must be checked before purchase.
Best for: Families or road-trip groups with compatible roof racks who need more enclosed space for luggage and bulky travel gear.
Not ideal for: Drivers with limited roof space, a low-capacity roof rack, or a preference for a guided tool-free mounting system.
- Brand:Maxsa Innovations
- Capacity:17 cu ft
- Weight capacity:165 lb
- Dimensions:55.12 x 35.04 x 16.14 inches
- Item weight:35.3 lb
- Material:ABS
- Opening:Dual-side
- Mounting:Strap
- Locking system:Keyed lock; two keys included
Our verdict“Pick the Maxsa Innovations box when maximum listed volume matters more than compact dimensions or guided installation.”
DNA MOTORING Lockable Rooftop Cargo Box, 11 Cubic Feet, Textured Black
The DNA MOTORING 11 cu ft box is the compact choice in this set: its 53 × 34 × 15-inch shell adds less listed volume than the Thule Pulse 2 M or either larger GarveeTech option, which may suit buyers who only need space for a few bags. It includes four mounting brackets, hardware, and a lock with keys, so the basic mounting and locking pieces are supplied. The side-opening lid stays open until closed, which can make loading less awkward when both hands are occupied. However, the key compromise is weather protection: its listing says it is not water resistant, unlike the waterproof Maxsa and GarveeTech boxes. It also requires crossbars and has a 110 lb evenly distributed load limit. I’d favor it for modest, fair-weather cargo, not exposed luggage or wet-weather trips.
Pros:- Compact 11 cu ft capacity for buyers who do not need a larger box.
- Impact-resistant ABS plastic construction.
- Includes four mounting brackets, hardware, and a lock with keys.
- Side-opening lid stays open until closed.
Cons:- Not water resistant, unlike the waterproof Maxsa and GarveeTech options.
- Requires vehicle crossbars.
- Maximum load is 110 lb when evenly distributed.
Best for: Drivers with crossbars who need a smaller box for occasional, fair-weather luggage rather than a large family load.
Not ideal for: Travelers carrying weather-sensitive gear or anyone without vehicle crossbars, since the box is not water resistant and requires them.
- Brand:DNA MOTORING
- Capacity:11 cubic feet
- Maximum load:110 lb when evenly distributed
- Dimensions:53 x 34 x 15 inches
- Material:ABS plastic
- Vehicle fit:Universal fit; requires crossbars
- Mounting:Roof mount; four ABS plastic mounting brackets included
- Closure:Lock with keys
- Water resistance:Not water resistant
Our verdict“Choose this DNA MOTORING box for modest cargo in fair weather, but skip it if weather protection is a priority.”
GarveeTech Rooftop Cargo Box Carrier, 14 Cubic Feet, Dual-Side Opening
The GarveeTech 14 cu ft carrier makes the most sense when weather protection and room for a full road-trip load matter more than a lightweight setup. Its listing describes the ABS shell as waterproof and UV-resistant, and its 165 lb capacity exceeds the Thule Pulse 2 M’s stated 75 kg limit by weight. Dual-side opening is convenient across a variety of parking situations, while included straps and keys provide basic mounting and locking components. Against the smaller GarveeTech 12 cu ft model, this version gives up some compactness for two additional cubic feet. The tradeoffs are a listed 44.8 lb product weight and a specific access routine: one side must be locked when opening the other. Roof-rack compatibility still needs checking, so I’d verify the vehicle fit before treating its universal-fit label as a guarantee.
Pros:- Waterproof, UV-resistant ABS shell is suited to exposed travel gear.
- 14 cu ft capacity and a 165 lb maximum load.
- Dual-side opening gives access from either side.
- Includes two keys and two straps.
Cons:- At 44.8 lb, it is heavier than the listed Maxsa Innovations box.
- One side must be locked when opening the other.
- Roof-rack compatibility must be checked for the vehicle.
Best for: Road-trippers who carry weather-sensitive luggage and want 14 cu ft of enclosed storage on a compatible roof rack.
Not ideal for: Drivers seeking a lighter or more compact carrier, or those who want to open either side without securing the other.
- Brand:GarveeTech
- Capacity:14 cubic feet
- Weight capacity:165 lb
- Dimensions:62.2 x 31.5 x 13.4 inches
- Product weight:44.8 lb
- Material:ABS
- Opening:Dual-sided
- Water resistance:Waterproof; UV-resistant
- Warranty:1 year
Our verdict“Choose this GarveeTech model for waterproof 14 cu ft storage if its weight and side-locking procedure suit your setup.”
GarveeTech Rooftop Cargo Box, 12 Cubic Feet, Dual-Side Opening, Black
This GarveeTech 12 cu ft box splits the difference between the 11 cu ft DNA MOTORING model and the larger 14 cu ft options. It offers waterproof, UV-resistant ABS construction and dual-side access in a shorter 54.3-inch body than the 14 cu ft GarveeTech’s 62.2-inch length. That combination favors drivers who want weather protection but have less room on the roof, though the listed dimensions and vehicle fit should still be checked. Its 165 lb maximum load matches the larger GarveeTech, while the 39 lb weight is lower than that model’s 44.8 lb. The main uncertainty is its warranty: the description states one year, while product information lists 30 days. Like the Thule Pulse 2 M, it needs compatible roof hardware, but it does not list the Thule’s torque-indicator mounting system.
Pros:- Waterproof, UV-resistant ABS shell.
- Dual-side opening provides access from either side.
- Shorter listed length than the 14 cu ft GarveeTech box.
- 165 lb load limit with two straps and two keys included.
Cons:- Warranty information conflicts: one year in the description and 30 days in product information.
- Provides less capacity than the 14 cu ft GarveeTech and 17 cu ft Maxsa boxes.
- Requires a compatible roof rack.
Best for: Drivers with compatible roof racks who want waterproof cargo protection in a shorter box than the 14 cu ft GarveeTech.
Not ideal for: Buyers who need maximum cargo volume, want clearly consistent warranty terms, or lack a compatible roof rack.
- Brand:GarveeTech
- Capacity:12 cubic feet (340 L)
- Maximum load capacity:165 lb
- Dimensions:54.3 x 31.5 x 13.4 inches
- Weight:39 lb
- Material:ABS
- Opening:Dual-sided
- Water resistance:Waterproof; UV-resistant
- Warranty:Conflicting listing: one year in description; 30 days in product information
Our verdict“Pick this model for a shorter waterproof box with dual-side access, but confirm the warranty and roof-rack fit before buying.”
D SOLUTIONS Hard Shell Rooftop Cargo Carrier, 11 Cubic Feet
The D SOLUTIONS 11-cubic-foot box suits drivers who want a hard shell for a smaller haul rather than the bulk of a full-size carrier. Its waterproof ABS construction and included key lock offer basic protection for packed gear, while the 110-pound load limit is higher than the SportRack Vista XL’s 100-pound limit. The tradeoff is capacity: at 11 cubic feet, it holds less than the SportRack’s 18 cubic feet, so it is a weaker fit for family luggage or bulky camping equipment. At 50.3 pounds, it is also the heaviest of these three options despite its smaller volume, making roof installation and storage more of a two-person job. It requires crossbars, and the advertised tool-free installation should not replace checking the hardware and vehicle fit before a trip.
Pros:- Waterproof ABS shell helps shield contents from rain.
- 110-pound listed load capacity exceeds the SportRack Vista XL’s 100-pound limit.
- Includes a lock, keys, mounting brackets, and hardware.
- 11 cubic feet adds enclosed storage without the footprint of larger boxes.
Cons:- Less storage volume than the 18-cubic-foot SportRack Vista XL.
- At 50.3 pounds, it is heavy to handle for an 11-cubic-foot box.
- Requires compatible vehicle crossbars.
Best for: Drivers with crossbars who need weatherproof space for a modest amount of luggage and value a higher listed load limit over maximum volume.
Not ideal for: Families packing several large bags or solo owners who need a lighter box to lift onto and off the roof.
- Volume:11 cubic feet
- Material:ABS plastic
- Dimensions:53 x 34 x 15 inches
- Weight:50.3 pounds
- Load capacity:110 pounds
- Mounting:Roof mount; requires crossbars
- Water resistance:Waterproof
- Included components:Cargo box, pair of keys, 4 mounting brackets, and mounting hardware
Our verdict“Choose this if a compact waterproof box and a 110-pound listed capacity matter more than easy handling or maximum storage volume.”
SportRack Vista XL Rear-Opening Cargo Box, Black
For buyers who need one box to handle several suitcases or bulky trip gear, the SportRack Vista XL’s 18 cubic feet is the clear capacity leader among these three. Its rear-opening design places access away from roadside traffic in many parking situations, a practical advantage over the side-opening Garvee box when loading beside a busy road. That larger shell does come with a 100-pound weight limit, lower than the D SOLUTIONS box’s 110 pounds and the Garvee’s listed 165 pounds, so the volume should not be mistaken for permission to carry a heavier load. Tool-free crossbar mounting and a lock and key add convenience, but buyers need to verify rack compatibility and bar spacing. Its dimensions also demand more roof space than either smaller option.
Pros:- 18 cubic feet offers the most storage of these three boxes.
- Rear opening can keep loading access farther from passing traffic.
- Tool-free crossbar mounting hardware simplifies installation and removal.
- Includes a lock and key and lists a 25-year warranty.
Cons:- 100-pound maximum load is below the listed limits of the D SOLUTIONS and Garvee boxes.
- Large dimensions may not fit every vehicle or roof rack.
- Rack fit and crossbar spacing need checking before purchase.
Best for: Families and road-trippers who need room for multiple bags and want to load from the rear of the vehicle.
Not ideal for: Drivers with limited roof space or those whose packed gear may exceed the 100-pound capacity.
- Capacity:18 cubic feet (510 L)
- Material:UV-resistant ABS plastic
- Opening:Rear-opening
- Dimensions:63 x 38 x 19 inches
- Weight capacity:100 pounds (45 kg)
- Crossbar spacing:23 5/8–29 3/4 inches (60–75.5 cm)
- Mounting:Tool-free crossbar mounting
- Compatibility:SportRack rack systems, square bars, round bars, and most factory racks
- Warranty:25 years
Our verdict“Pick the Vista XL if family-size volume and rear access outweigh its lower load limit and larger roof footprint.”
Garvee Rooftop Cargo Box Carrier, 12 cu ft, Dual-Side Opening
The Garvee 12-cubic-foot box makes the most sense for drivers who want to reach their cargo from either side of the car. That flexibility can help when a wall, another parked vehicle, or roadside traffic blocks one side; the rear-opening SportRack Vista XL is better suited to drivers who prefer access from behind. Garvee also lists a 165-pound maximum capacity, above the other two boxes here, though buyers should confirm their vehicle’s roof and rack limits rather than treating the box rating as the vehicle’s safe payload. Its 36-pound weight is easier to manage than the 50.3-pound D SOLUTIONS box. The main caveat is conflicting warranty information: the description says one year, while product information says 30 days. Fit still depends on a compatible roof rack.
Pros:- Dual-sided opening provides access when one side of the vehicle is blocked.
- 36-pound weight is lighter than the D SOLUTIONS box.
- 12 cubic feet provides more room than the D SOLUTIONS box.
- Waterproof, UV-resistant ABS shell and included keys and straps.
Cons:- Warranty terms conflict: the description states one year, while product information lists 30 days.
- Requires a compatible roof rack.
- The 165-pound box rating does not override the vehicle or rack’s own load limits.
Best for: Drivers with a compatible roof rack who want side access from either side and a lighter box with a high listed capacity.
Not ideal for: Buyers who need a clearly stated, consistent warranty or who lack a roof rack.
- Volume:12 cubic feet (340 L)
- Material:ABS
- Dimensions:54.3 x 31.5 x 13.4 inches
- Item weight:36 pounds
- Maximum capacity:165 pounds
- Mounting and fit:Roof mount; requires a roof rack
- Opening:Dual-sided
- Water resistance:Waterproof; UV-resistant
- Warranty:One year stated in description; product information lists 30 days
Our verdict“Choose the Garvee if dual-side access and easier handling are priorities, but confirm rack limits and warranty coverage before buying.”
How We Picked
I compared these eight car roof cargo boxes around the decisions that affect day-to-day ownership: listed capacity, opening direction, hard-shell construction, locking features where specified, and the practical fit questions buyers need to resolve. I gave weight to the balance between carrying room and access, since a box that holds more can still be awkward if its lid is difficult to reach from the available side of the vehicle. I also considered how clearly each model’s stated features help a buyer distinguish it from similar-capacity options.
The ranking favors a useful mix of capacity and loading convenience rather than capacity alone. That puts the Thule Pulse 2 M first as a balanced 14-cubic-foot dual-side option, while the larger Maxsa earns a distinct role for buyers seeking more stated volume. Models with narrower capacities or less distinctive listed access features rank lower, not because they cannot suit a particular vehicle, but because buyers have more fit and use-case details to verify. Product names and listed specifications are not a substitute for confirming roof-rack compatibility, dimensions, and vehicle clearance.

Factors to Consider When Choosing Car Roof Cargo Boxes
Before choosing among these boxes, I would check the whole carrying setup rather than comparing capacity figures alone. Roof-rack compatibility, lid access, and the items you intend to carry can change which model makes sense.
Match the Box to Your Rack and Vehicle
Start with the vehicle and rack maker’s limits, then check the cargo box’s mounting requirements and dimensions. The roof’s permitted load generally includes the box, rack, and cargo together, so a spacious model can leave less allowance for what you pack. Check crossbar spacing and shape against the box’s mounting hardware rather than assuming a universal fit. Measure the available roof area and consider hatch or tailgate movement, especially on SUVs and vehicles with liftgates. A box that fits the rack can still interfere with a hatch or sit awkwardly relative to the windshield. If compatibility details are unclear, get confirmation before buying rather than relying on the product’s capacity label.
Choose Capacity by the Shape of Your Cargo
Cubic feet describe volume, not the length or shape of an item that will fit. Skis, folding chairs, strollers, and bulky soft bags have different dimensional needs, so check interior length and opening dimensions where available. The 17-cubic-foot Maxsa is the lineup’s largest by stated volume, but that figure alone cannot confirm that a long item will fit. Smaller 11- or 12-cubic-foot boxes may be a better match for lighter trips or vehicles with limited roof space. Avoid buying extra capacity simply because it sounds useful: a larger box can add bulk and make loading or storage harder. Sketching your typical cargo layout can reveal whether usable dimensions matter more than the headline volume.
Pick an Opening Direction That Works Where You Park
Dual-side opening can make loading easier when access from one side is blocked by a wall, another vehicle, or traffic. A rear-opening design such as the SportRack Vista XL may better fit a routine where loading from behind is convenient, but the hatch and box placement still need checking together. Think about where you usually park and which side of the vehicle is safe to stand beside. Lid direction also affects how easily you can reach cargo without climbing onto a running board or stretching across the roof. Do not assume that two boxes with the same capacity offer the same loading experience. Choose based on the access you can use most often, not just the feature label.
Treat Locks and Shell Construction as Part of the Use Case
A hard shell provides an enclosed space for travel, but the exact construction and locking details differ by model and should be checked in the product specifications. The DNA MOTORING model is explicitly described as lockable, while buyers should verify the locking system and included keys or hardware on other options. A lock can deter casual access, but it does not make valuables safe to leave unattended. For frequent use, inspect how the lid closes and whether the opening mechanism is manageable for the people who will load it. Also think about where the box will live when it is off the vehicle; storage space at home can be as limiting as roof space on the road. A larger shell may be less convenient to remove and store between trips.
Account for Clearance, Driving, and Loading Limits
A roof box changes a vehicle’s height and adds weight above the cabin, so check total clearance before entering garages, parking structures, or drive-throughs. The box and its cargo also count toward roof-load limits, and the vehicle maker’s guidance takes precedence over a box’s capacity. Pack heavier items low and distribute the load according to the box and vehicle instructions rather than concentrating weight at one end. A roof-mounted box can affect handling and wind exposure, particularly when loaded, so follow speed and use guidance from the manufacturers. Recheck the mounting points and closures as directed, especially before a long drive. These steps matter with every option here, whether it holds 11 or 17 cubic feet.
Decide Whether Paying for More Capacity or Access Helps You
Extra capacity is most useful when it replaces a recurring packing problem, not when it simply leaves unused space on the roof. The Maxsa stands apart on listed volume, while the Thule Pulse 2 M combines a more moderate 14 cubic feet with dual-side access. Several 12-cubic-foot Garvee-family options also provide dual-side opening, which may be enough for buyers whose priority is reaching cargo from either side. Compare the exact model, dimensions, mounting system, and included hardware instead of treating similar names as proof of identical specifications. Paying more makes sense when a better fit, easier access, or a feature you will use regularly justifies it. If your needs are occasional and modest, prioritize confirmed compatibility and manageable size over capacity you may not use.
Frequently Asked Questions
Will any of these cargo boxes fit my existing roof rack?
Not automatically. Compatibility depends on your rack’s crossbar style and spacing, the box’s mounting hardware, and the vehicle maker’s roof-load limits. Compare those details for the exact product model before ordering, and confirm the combined weight of rack, box, and cargo stays within the vehicle limit. Also check whether the box sits far enough from the hatch or tailgate to open fully. If a listing does not provide a measurement you need, ask the manufacturer rather than guessing from capacity.
Is a 17-cubic-foot box always a better choice than a 12- or 14-cubic-foot model?
No. The Maxsa has the highest listed capacity here, but cubic feet do not tell you whether your particular gear fits or whether the box works well on your roof. A larger box may take up more roof area and can be harder to load, remove, or store. A smaller dual-side model may be more practical if your usual cargo is limited and access from either side matters. Compare interior dimensions and your vehicle’s permitted roof load before deciding that more volume is useful.
Should I choose dual-side opening or rear opening?
Choose the opening direction that matches where you park and how you load. Dual-side options, including the Thule Pulse 2 M and several Garvee models, can provide access when one side of the vehicle is blocked. The SportRack Vista XL’s rear-opening format may suit buyers who prefer loading from behind, but verify that the hatch can still open without interference. If you regularly park close to a wall or another car, that constraint may matter more than a small difference in stated capacity. Check the opening location and vehicle clearance before choosing.
Can I leave valuables in a locked roof cargo box overnight?
A lockable lid can help restrict casual access, but it should not be treated as strong security for valuable items. The DNA MOTORING box is specifically described as lockable; for other models, confirm exactly what locking hardware is included. Avoid leaving electronics, documents, or other high-value belongings in the box when the vehicle is unattended. Park in a secure, well-lit location and follow the box maker’s guidance for closing and locking it. A roof box is best treated as travel storage, not a substitute for a secure vehicle compartment.
What should I check before driving with a newly installed roof box?
Confirm the box and rack are mounted according to their instructions, then check that every clamp, latch, and lid closure is secure. Stay within both the vehicle’s roof-load limit and the box’s own load guidance; the rack and box weights count toward the total. Make sure the cargo is restrained inside and does not obstruct the lid from closing properly. Check overall vehicle height before entering low-clearance areas, and follow manufacturer guidance on driving with the box attached. Recheck the mounting hardware as directed during the trip, particularly after the initial drive.
Conclusion
For most buyers, I would start with the Thule Pulse 2 M as the best overall: its 14-cubic-foot capacity and dual-side opening balance room with access. The Maxsa Innovations is the best choice when maximum stated capacity comes first, while the lineup’s 12-cubic-foot GarveeTech and Garvee dual-side models are worth comparing as value-oriented options once their fit and included hardware are confirmed. For a first-time buyer, I would favor a box whose dimensions, mounting details, and opening direction are clearly verified for the vehicle rather than choosing the largest model; the Thule’s balanced format makes it a sensible starting point. Buyers who specifically want rear access should look at the SportRack Vista XL, and those who want a named lockable option can compare the DNA MOTORING box. My final choice would come down to rack compatibility, cargo dimensions, and which side of the vehicle I can safely reach.
