If you are considering pidock car rooftop cargo box alternatives, you likely value its dual-side access and tool-free mounting. The Pidock 16 cu ft Hard Shell Roof Box offers 15.5 cubic feet of capacity and a 130 lb load limit. Its ABS and PMMA shell provides water resistance and durability for standard road trips. The streamlined 58.3-inch length fits most garages, while the wide opening simplifies loading bulky items from either side of your vehicle.

However, you might need different specifications. Some drivers require higher load capacities, such as the 165 lb limit found in other hard shell options. Others may prefer narrower widths for specific crossbar setups or larger volumes for extended trips. We selected these alternatives because their specs overlap with the original product. This list includes dual-side opening models with varying capacities, dimensions, and load ratings. You can compare these practical options to find the best fit for your roof rack and cargo needs.

How each alternative compares

Goplus 14 cu ft Dual-Side Opening Roof Box

The Goplus 14 cu ft box is narrower at 31 inches wide, making it better for vehicles with narrow crossbars. It offers a higher load capacity of 165 lbs, allowing you to carry heavier gear than the Pidock’s 130 lb limit. However, it is taller at 15 inches, which may affect garage clearance compared to the Pidock’s 13-inch height. You get dual-side access and hard shell protection, but the reduced width and increased height change the fit. Choose this if your roof rack has limited width or you need to haul heavier loads.

Ausum Motor 14 cu ft Dual-Side Box

The Ausum Motor 14 cu ft box is lighter at 45 pounds, which may help with fuel efficiency slightly, though it has a lower load capacity of 110 lbs compared to the Pidock’s 130 lbs. It shares the dual-side opening feature, providing similar loading convenience. The glossy black finish offers a different aesthetic. You give up some load weight tolerance for a potentially lighter unit. This option suits drivers who prioritize side access and specific rack spacing needs over maximum cargo weight. It is a practical choice for moderate loads where weight savings matter.

Runave 15.5 cu ft Dual-Side Roof Box

The Runave 15.5 cu ft box matches the Pidock’s dimensions and capacity almost exactly, including the 13-inch height and 35.4-inch width. It offers a higher load capacity of 150 lbs, giving you 20 lbs more carrying power. Like the Pidock, it features dual-side opening and a hard shell construction. The white color option is available in both. You get nearly identical physical specs but with a stronger weight limit. Pick this if you want the same footprint and access but need to carry slightly heavier items on your roof trips.

DNA Motoring 13 cu ft Hard Shell Roof Box

The DNA Motoring 13 cu ft box is shorter in length at 56.3 inches, making it more suitable for smaller vehicles. It is significantly taller at 16.3 inches, which increases wind drag compared to the Pidock’s 13-inch profile. The load capacity is lower at 110 lbs. You sacrifice volume and height clearance for a more compact footprint. It offers hard shell protection and side access. Choose this if your vehicle is smaller and you need a box that sits lower and does not extend as far back. It is best for moderate cargo needs with space constraints.

Relaxcabine 14 Cu Ft Hard Shell Roof Box

The Relaxcabine 14 cu ft box is 62.5 inches long, making it longer than the Pidock’s 58.3 inches. It offers a higher load capacity of 150 lbs. The width is narrower at 32.5 inches. It features dual-side opening and a hard shell. You gain extra length for longer items but lose some width. The height is 13.2 inches, very close to the Pidock. This option suits drivers who need side access and moderate capacity but have longer gear to transport. It is a practical choice for road trips where length matters more than width.

PM Performotor 15 cu ft Dual-Side Box

The PM Performotor 15 cu ft box is the longest at 80 inches, providing ample space for long items like skis. It is narrower at 30 inches and has the same 13-inch height as the Pidock. It lacks a stated load capacity in the provided data, so you cannot compare weight limits directly. You get dual-side access and hard shell construction. Choose this if you need to transport very long equipment and have a longer roof rack. The narrow width may not fit all crossbar setups. It is best for drivers prioritizing length and side loading convenience.
