Frequently Asked Questions

What is the difference between dynamic and static roof load limits?

Dynamic load limit is the maximum weight your vehicle roof can carry while driving, typically 50-100kg. Static load limit is much higher (150-300kg) and applies when the vehicle is parked and stationary.

How do I find my vehicle's roof load limit?

Check your vehicle's owner manual, the sticker inside the driver's door frame, or contact your vehicle manufacturer. You can also search online using your vehicle's make, model, and year.

Can I exceed the dynamic load limit if I drive slowly?

No, never exceed the dynamic load limit regardless of driving speed. This limit is set for safety and structural integrity of your vehicle's roof, and exceeding it can cause permanent damage or dangerous situations.

What happens if my rooftop tent is too heavy for my vehicle?

An overloaded roof can cause roof damage, affect vehicle handling and braking, increase fuel consumption, and potentially lead to accidents. It may also void your vehicle warranty and insurance coverage.

How much weight do people add to a rooftop tent?

People typically add 60-150kg depending on the number of occupants. Plus bedding, clothes, and gear can add another 15-30kg. Always account for the total occupied weight, not just the tent's empty weight.

Do I need a safety margin below the maximum load limit?

Yes, it's recommended to stay 20-30% below maximum capacity for safety. This accounts for load distribution variations, dynamic forces while driving, and provides a buffer for unexpected additional weight.

What if my roof rack has a lower capacity than my vehicle's roof limit?

Always use the lowest capacity rating among your vehicle roof limit, roof rack capacity, and tent mounting system. The weakest link determines your safe maximum load.

Can I use a rooftop tent on any vehicle with roof rails?

Not necessarily. While roof rails are needed, you must verify that your vehicle's load limits, roof rail capacity, and roof rack system can all support the tent's weight plus occupants safely.
