165 Lb or 110 Lb Roof Cargo Boxes
Load Capacity
The Maxsa Innovations 17 cu ft Hard Shell Cargo Box supports up to 165 lbs of evenly distributed weight. This higher limit allows you to carry heavier items like camping equipment or sports gear without exceeding the manufacturer's safety guidelines. In contrast, the DNA Motoring 11 cu ft Roof Box has a maximum load capacity of 110 lbs. While sufficient for standard luggage, this lower threshold restricts the amount of dense material you can safely transport. If you frequently haul heavy tools or bulkier outdoor supplies, the Maxsa unit offers a significant 55 lb advantage. This extra margin provides greater flexibility when packing for extended trips or family vacations where weight distribution is critical for vehicle stability.
Capacity
Storage volume is a primary differentiator between these two carriers. The Maxsa Innovations model provides 17 cubic feet of internal space, accommodating larger bundles of luggage, multiple duffel bags, or seasonal clothing sets. This generous volume suits families or travelers needing substantial room for gear. The DNA Motoring option offers 11 cubic feet of storage. While smaller, this capacity is adequate for a few suitcases or light weekend bags. The 6 cubic foot difference means the Maxsa box can hold roughly 50% more volume. For users prioritizing maximum storage over compactness, the larger Maxsa box is the practical choice. However, if your cargo needs are modest, the smaller DNA Motoring box may suffice without taking up excessive roof space.
Opening
Access to your cargo varies significantly between the two designs. The DNA Motoring carrier features a side-opening lid that swings open to a width of 14 inches. This lateral access allows you to reach items from the side of the vehicle, which can be convenient when parked in tight spaces where the rear is blocked. The Maxsa Innovations box does not specify its opening mechanism in the provided data. Without explicit details on whether it opens from the side or the rear, it is unclear how easily you can access contents when parked close to other objects. If side access is a priority for your parking habits, the DNA Motoring design offers a clear functional advantage that you can verify against your specific needs.
Shell Type
Both products utilize hard-shell construction to protect your belongings from weather and impact. The DNA Motoring box is explicitly constructed from rugged, impact-resistant ABS material. This specific polymer choice suggests a focus on durability against road debris and minor collisions. The Maxsa Innovations box is described as a hard shell but does not specify the exact plastic composition in the available data. Hard shells generally offer better weather sealing and security than soft bags. Since both are hard shells, they both provide a solid barrier against rain and theft. However, the explicit mention of ABS material for the DNA Motoring unit gives you more confidence in its material resilience compared to the unspecified shell of the Maxsa model.
Dimensions
Physical footprint affects aerodynamics and roof space usage. The Maxsa Innovations box measures 55.1 inches in length, 35 inches in width, and 16.1 inches in height. The DNA Motoring box is slightly shorter at 53 inches long, narrower at 34 inches wide, and lower at 15 inches high. The DNA Motoring unit is more compact in all three dimensions. This reduced size may result in slightly less wind drag and noise, potentially improving fuel efficiency on long highway drives. The Maxsa box is larger and taller, which might increase aerodynamic resistance. If you have a smaller vehicle roof or are sensitive to wind noise, the smaller DNA Motoring dimensions are a practical benefit. The Maxsa box requires more roof real estate.
Which roof cargo box fits your needs
Heavy gear haulers needing max weight
The Maxsa Innovations box supports 165 lbs. This higher load capacity lets you carry heavier camping equipment or sports gear. Its 17 cubic feet of volume provides ample space. You benefit from the robust 165 lb limit for demanding trips where weight is a primary concern.
Users wanting side access for bulky items
The DNA Motoring carrier opens from the side. This feature allows you to store bulky items easily without removing the box. It offers 11 cubic feet of space. The side-opening lid stays open for convenient access, making it practical for loading large or awkwardly shaped cargo quickly.
Those prioritizing aerodynamic efficiency and space
The Maxsa Innovations model features a 17 cubic feet capacity with an aerodynamic shape. This design cuts wind resistance and noise. You get a smoother ride and improved fuel efficiency. The larger volume accommodates more luggage, while the streamlined profile ensures quieter travel on long road trips.

Frequently asked questions
Can a 165 lb roof cargo box damage my car?
A 165 lb load is safe if your vehicle’s roof rack supports it. The Maxsa Innovations box weighs 35.3 pounds and holds 165 lbs. Always check your car’s manual for total roof weight limits. Distribute weight evenly to protect your vehicle’s structure and roof rails during travel.
Which is better for camping gear, 165 lb or 110 lb?
The 165 lb capacity is better for heavy camping loads. The Maxsa Innovations model offers 17 cubic feet of space and supports 165 lbs. This allows you to carry bulky items like tents and sleeping bags. The 110 lb option is lighter but holds less weight.
Does a higher load capacity mean the box is heavier?
Not always, but strong materials often add weight. The Maxsa 165 lb box weighs 35.3 pounds. DNA Motoring’s 110 lb box does not list its weight. Higher capacity boxes often use thicker shells. This adds durability but may increase the empty weight of the carrier.
Can I fit a 17 cubic foot box on small crossbars?
Yes, if your crossbars support the width. The Maxsa box is 35 inches wide. Ensure your bars are spaced correctly for secure mounting. The DNA Motoring box is 34 inches wide. Both use roof mount systems. Check your bar length before buying a larger volume box.
Is side access important for a 110 lb roof box?
Side access helps you load gear without removing the box. DNA Motoring highlights side-access loading for its 110 lb model. This is useful for narrow parking spots. The Maxsa 165 lb box uses a hard shell design. Check if your preferred box allows easy side access.
Will a 165 lb box affect my fuel economy?
Any roof box adds drag and reduces fuel efficiency. The Maxsa box has an aerodynamic hard shell to reduce noise and drag. DNA Motoring also uses an aerodynamic design. Heavier boxes may slightly increase weight-related drag. Keep the box empty when not in use to save gas.
Are both boxes lockable for security?
Both models offer security features. DNA Motoring explicitly lists its box as lockable. The Maxsa Innovations box is described as secure. Hard shells generally provide better protection than soft covers. Verify that the lock mechanism works with your crossbar keys for added peace of mind.
What is the difference in dimensions between the two?
The Maxsa box is 55.1 inches long and 16.1 inches high. DNA Motoring is 53 inches long and 15 inches high. The Maxsa model is slightly larger in all dimensions. This extra space supports its higher 165 lb capacity. Measure your roof space to ensure fit.
