Its dimensions (63 x 38 x 19 inches) provide ample room for various items. Despite its large size, the cargo box is relatively lightweight at 28 pounds, which aids in easier handling and installation.

However, the aerodynamics could be affected due to its size and shape, potentially impacting fuel efficiency. The maximum weight capacity of 100 pounds should suffice for most needs but may be limiting for heavier loads.
