How the alternatives compare
DNA Motoring 13 cu ft Hard Shell Roof Box
The DNA Motoring model offers 13 cubic feet of capacity, which is smaller than the Pidock’s 15.5 cubic feet. It weighs less and has a height of 16.3 inches, making it slightly taller than the Pidock’s 13-inch profile. This extra height may affect aerodynamics or garage clearance. It retains the dual-sided opening feature and tool-free installation that you find in the Pidock. The load capacity is rated at 110 pounds, which is lower than the Pidock’s 130-pound limit. If you need less volume but still want side access, this compact box is a practical choice. It fits well on vehicles where space is limited. The textured black finish provides a different aesthetic compared to the smooth black of the Pidock.
Relaxcabine 15.5 Cu Ft Dual-Open Roof Box
The Relaxcabine box matches the Pidock exactly in dimensions, measuring 58.3 by 35.4 by 13 inches. It also provides 15.5 cubic feet of capacity and dual-sided opening. The main difference is weight. The Relaxcabine weighs 34.3 pounds, which is nearly three pounds heavier than the Pidock’s 31.5 pounds. This added weight might slightly impact fuel efficiency or roof rack stress. Both units are lockable and feature hard shells. If you prefer a slightly heavier build for perceived durability, the Relaxcabine is a direct alternative. It offers the same loading convenience and storage volume. The choice between them often comes down to price or specific brand preference, as the functional specifications are nearly identical for standard roof rack mounting.
VUMALL 13 Cu.ft Dual-Open Hard Shell
The VUMALL box is narrower than the Pidock, measuring 30 inches wide compared to the Pidock’s 35.4 inches. It has 13 cubic feet of capacity, which is 2.5 cubic feet less than the Pidock. The length is similar at 56 inches. It also features dual-sided opening and is lockable. This narrower profile makes it a better fit for vehicles with narrower roof racks or for drivers who prioritize a lower wind noise profile. It weighs 27.8 pounds, making it the lightest option in this comparison. If you do not need the full 15.5 cubic feet, this box saves space and weight. It is ideal for moderate loads where side access is still required. The compact width ensures it does not extend far beyond your vehicle’s sides.
Yakima SkyBox NX XXL 22 cu ft Hard Shell Box
The Yakima SkyBox NX XXL is significantly larger than the Pidock. It offers 22 cubic feet of capacity, which is 6.5 cubic feet more. This makes it suitable for heavy loads and long trips requiring maximum storage. It is a high-capacity carrier designed for users with robust roof racks. The Pidock is more compact and easier to handle for everyday use. The Yakima model prioritizes security and space over compact simplicity. It is lockable and features hard shell construction. If you frequently carry bulky gear or need to transport a large amount of luggage, this larger box is the better choice. It sacrifices the compact nature of the Pidock for substantial additional volume. Ensure your roof rack can support the increased load and dimensions.
Eylar SRX-175 Overlanding Cargo Case
The Eylar SRX-175 is a rotomolded case designed for overlanding and truck bed storage, not primarily for roof mounting. It measures 47.2 by 18.4 by 13.2 inches. This is much smaller in volume than the Pidock’s 15.5 cubic feet. It is intended for transporting sensitive equipment where rugged, weatherproof protection is critical. The Pidock is built for aerodynamic roof use with dual-sided access. The Eylar case is lockable and features a robust construction suited for off-road conditions. If you need a secure container for truck beds or off-road expeditions, this is a specialized alternative. It does not offer the same loading convenience or roof rack compatibility as the Pidock. Choose this if your primary use case is overlanding rather than standard cargo transport.
VISRACK 13 cu ft Hard-Shell Roof Box
The VISRACK box is narrower than the Pidock, with a width of 30.3 inches compared to 35.4 inches. It provides 13 cubic feet of capacity, which is less than the Pidock’s 15.5 cubic feet. It weighs 27.8 pounds, making it lighter than the Pidock. This model also features dual-sided opening for flexible loading in tight spaces. The height is 13.8 inches, slightly taller than the Pidock’s 13-inch profile. It is designed for drivers who prioritize flexible access and weather-resistant storage over maximum volume. The narrower design makes it suitable for vehicles with narrower racks. If you need side access but have limited width clearance, this box is a practical option. It offers a balance of accessibility and compact footprint.
