How to Choose the Right Cargo Bar
-
Check your truck bed cap
Your truck’s specific bed cap dictates which hardware fits securely. The Rough Country 42-inch crossbars are designed specifically for compatible bed caps, ensuring a stable mount. You must verify that your truck’s bed cap matches the mounting requirements for these aluminum bars. If your setup differs, these bars may not install correctly. Always measure your bed cap’s mounting points before purchasing. This ensures the 8.25-inch width and 44.3-inch length align with your truck’s geometry. Proper compatibility prevents movement during transit and protects your vehicle’s finish from damage caused by ill-fitting hardware.
-
Compare load capacity needs
Determine how much weight you intend to carry. The Rough Country bars are built for heavy-duty gear, leveraging their 26-pound aluminum construction for high capacity. If you only need to move light items, this robust build might be overkill. The SCITOO carrier weighs just 13.5 pounds, making it suitable for lighter loads like a single bike. Assess your typical cargo weight. Heavier gear requires the sturdier platform of the Rough Country bars. Lighter items fit well on the SCITOO option. Matching your load to the bar’s strength ensures safety and prevents structural failure under stress.
-
Measure bar dimensions
Bar size affects how much gear you can store. The Rough Country crossbars measure 44.3 inches in length and 8.25 inches in width. This provides a broad platform for bulky items. The SCITOO carrier is slightly longer at 44.5 inches but narrower in profile. Consider the footprint of your cargo. Wide items need the 8.25-inch width of the Rough Country bars. Long, narrow items might fit the SCITOO design better. Accurate measurements prevent overhang issues. Ensure your gear fits within the bar dimensions to maintain vehicle balance and aerodynamics during travel.
-
Consider material durability
Material choice impacts longevity and maintenance. The Rough Country bars are made of aluminum, offering a balance of strength and corrosion resistance. Aluminum is ideal for outdoor use on trucks. The SCITOO carrier is silver, likely aluminum or steel, weighing less at 13.5 pounds. Aluminum resists rust, which is crucial for truck beds exposed to elements. If you transport gear in wet conditions, aluminum is a reliable choice. Check the material specifications to ensure it matches your environment. Durable materials reduce the need for frequent replacements and maintain structural integrity over time.
-
Verify intended use
Match the carrier to your primary activity. The Rough Country bars are best for general heavy-duty gear on bed caps. They offer T-slot versatility for various accessories. The SCITOO carrier is specifically for single bike transport. It is a low-profile option for trucks with existing bars. If you haul bikes, the SCITOO design is optimized for that task. If you carry tools or boxes, the Rough Country bars provide a flat, sturdy surface. Define your main use case first. This narrows your choices to the product that supports your specific hauling needs effectively.
