Establish the permitted carrier application
Ask for the applicable vehicle instructions and a fitment confirmation identifying the exact model, production version and roof arrangement. Do not infer a load allowance from an accessory photograph or transfer a Bao 5 carrier specification to Tai 7. The VIN and model-code guide helps identify the candidate before the supplier selects hardware. Where the relevant information cannot be established, keep the carrier plan unresolved. Buying a universal kit first can leave the owner searching for a justification for equipment that was never suitable.
Count accessories and contents together
The bars, mounting hardware, box and luggage all contribute to the roof system's mass and to the vehicle's overall loading. Compare the applicable vehicle and accessory limits and follow the more restrictive relevant requirement. Do not confuse a static-load advertisement with a permitted driving load. Passenger weight and interior cargo also matter. Ask a competent supplier to resolve unclear ratings instead of choosing the largest number in a collection of brochures. A roof box can contain plenty of empty volume after the allowable load has already been reached.
Check installation around glass and moving parts
Have the correct mounts, positions and tightening procedure established by an appropriate installer. Confirm any restrictions involving roof glass or opening equipment and clearance to the tailgate or other moving parts. Do not drill, clamp or modify the roof on the basis of a generic online demonstration. Record the installed part identifiers and retain the instructions for later refitting. The version-specific parts checks can help when suppliers describe a kit as suitable for all Tai 7 vehicles without documenting its application.
Measure the complete parking envelope
Measure the finished height with the actual equipment and check the relevant clearance at home, hotels, shopping centres and charging locations. Include the safe margin required by the facility or installer rather than aiming for theoretical millimetre clearance. Assess turning and loading space as well as height. The home charging plan should remain usable with the new setup. An installation that fits in an open driveway may become impractical in a garage where the roof box, cable and doors all compete for space.
Make loading manageable for the person travelling
Consider who lifts the equipment, how often the box must be accessed and whether it can be loaded safely in the normal parking location. Do not climb on unstable objects or use vehicle trim as a makeshift step. Put frequently needed items where they can be reached without unpacking the whole roof load beside traffic. Follow the supplier's securing and inspection instructions. A useful carrying solution should work in rain and fading light as well as during a carefully arranged sales demonstration with several people helping.
Revisit route and energy assumptions
External equipment can change aerodynamic demand and handling, so do not assume the original consumption or range estimate remains valid. The effect depends on load, shape, speed and conditions; a fixed universal penalty would be misleading. Follow the vehicle and accessory operating restrictions and plan conservative stops. Use the route assessment if the journey includes uneven access or locations where recovery is difficult. Inspect the system as instructed and stop safely if unusual movement or noise appears rather than accepting it as a normal accessory characteristic.
Keep freight and purchase descriptions accurate
List any carrier included with the car, its condition and the evidence supporting fitment. Agree whether it ships installed or separately packed under the carrier's requirements, and update the transport dimensions accordingly. Used hardware needs inspection for damage or missing parts, not just a new lock key. Do not describe an unverified accessory as factory equipment. If the family trip only works with an unapproved roof arrangement, reconsider the luggage or vehicle choice before committing to import costs.
Buyer checklist
- Confirm the exact permitted carrier and mounting system.
- Include fittings and luggage in all applicable load calculations.
- Measure installed height and practical access.
- Update energy assumptions and freight dimensions.
Questions and answers
Do roof rails establish a safe load?
No. Their appearance does not establish the permitted load or suitable mounting kit. Use the exact vehicle and accessory documentation.
Can a carrier stay fitted during export?
That depends on the carrier's requirements and the agreed vehicle dimensions and securing plan. Confirm the arrangement before booking rather than assuming the standard vehicle dimensions still apply.
Reference information
Use the applicable market and year documentation for equipment and operating limits. The references have their own market and publication scope; they do not establish the condition, fitted equipment or destination approval of an individual vehicle.
