As per the applicable laws and regulations, it is prohibited for passenger vehicles to transport goods beyond the external luggage rack. The length of the luggage rack should not exceed the vehicle's carriage, while the height of the rack must stay within 0.5 meters. Additionally, the distance from the point should not exceed 4 meters. In general, the combined measurement of the luggage rack and roof tent (when not deployed) is typically around 0.4 meters, which complies entirely with the specified requirements. It is worth noting that the roof tent remains packed away and is solely intended for use at camping sites.
