Buying Guide: Key Considerations For Roof Cargo Carriers
- Capacity needs: Choose cubic feet by typical trip gear, number of travelers, and whether you’re carrying bulky items like tents or sleeping bags.
- Hard box vs. soft bag: Rigid boxes offer structure and sometimes easier loading; soft bags maximize storage flexibility and often cost less. Consider weather resistance and long-term durability.
- Mounting and compatibility: Check whether your vehicle has a roof rack, crossbars, or bare roof. Some bags fit without racks, but most benefit from a secure mounting system.
- Weather resistance: Waterproof materials and sealed seams protect contents. Ensure materials are UV-resistant to prevent sun damage over time.
- Access style: Rear-opening designs provide quick access from behind the vehicle; top-opening options may require lifting over the vehicle roof.
- Security: Luggage locks and tamper-resistant features are worth considering for travel in unfamiliar areas.
- Weight distribution: Distribute weight evenly and keep the load within the car’s roof load limit to maintain handling and fuel efficiency.
- Storage and transport: Consider how much space you’ll have when not in use and how you’ll store the carrier when empty.
