Are roof top tents safe for cars?
Roof-top tents can be safe when properly installed and used within your vehicle’s rated limits, but they introduce extra weight, wind resistance, and handling changes that require careful setup and ongoing maintenance.
A roof-top tent sits on your vehicle’s roof, typically mounted to a roof rack or bars. They add significant weight and raise the vehicle’s center of gravity, which can affect braking, steering, and rollover risk if not used correctly. Safety hinges on following manufacturer weight ratings, using the right mounting system, and practicing prudent driving and maintenance.
The following article outlines key safety considerations, installation requirements, and best practices for using roof-top tents on cars, with practical steps you can take to reduce risk while enjoying overland and camping adventures.
Weight, mounting and vehicle compatibility
Before you evaluate safety, consider these critical factors related to weight, hardware, and how well the system fits your vehicle.
- Check the vehicle’s roof load rating (static and dynamic) and ensure the RTT’s weight, plus occupants and gear, stays within that limit.
- Use a manufacturer-approved mounting system designed for your vehicle and RTT; follow torque specs and re-torque as recommended.
- Ensure the roof rack or mounting base distributes weight evenly and is rated above the RTT’s weight to avoid concentrated stress on rails or crossbars.
- Account for the RTT’s occupancy and weight rating; don’t exceed the listed limits for people sleeping in the tent.
- Consider vehicle height and diffuser/airflow impacts; ensure clearance with garages, low branches, and drive-throughs.
Accurate installation and compatible components are the foundation of RTT safety, reducing the risk of structural damage or detachment on the road.
Safe use and everyday operation
Once installed, follow these practices to minimize risk during travel, camping, and use of the tent.
- Before each trip, verify that all latches, clamps, and mounting hardware are secure, and that the ladder is properly stowed when driving.
- Drive with awareness of increased vehicle height and wind resistance; reduce speed in high winds or when passing trucks and over open exposure areas.
- Avoid driving with the tent open or deployed; retract and secure the tent before moving, and never climb on the tent while the vehicle is in motion.
- Choose level, stable camping sites; use leveling aids or blocks if provided, and keep the ladder foot on solid ground to prevent tipping during entry and exit.
- Regularly inspect fabric, zippers, seams, and frame components for wear or damage; address issues promptly to prevent failure in the field.
- Check with your insurer or vehicle manufacturer about coverage for RTT-related modifications and warranties; ensure they don’t conflict with safety and liability expectations.
Following these practices helps keep you and your passengers safe, while preserving the RTT’s functionality and longevity.
Additional considerations
In addition to the above, consider local regulations, road conditions, and weather patterns. Some areas have rules about rooftop loads, and severe weather can increase risks of wind uplift or fatigue on mounting hardware. Regular maintenance and prompt attention to signs of wear are essential for long-term safety.
Summary
Roof-top tents can be a safe and convenient camping option when you: (1) verify and respect weight limits for both the vehicle and the tent, (2) install with approved hardware and follow manufacturer guidelines, (3) drive with awareness of the changes in handling and aerodynamics, and (4) perform routine inspections and maintenance. Safety is a moving target that depends on proper equipment, careful installation, responsible use, and ongoing upkeep. By prioritizing these elements, many drivers can enjoy rooftop camping with minimized risk.
