Specifications side by side

How to Choose the Right Truck Tool Box

1. Check Wheel Well Dimensions

   You must measure your wheel well before buying. The VEVOR ABS Wheel Well Toolbox 6.6 Gal has a width of 8.7 inches. This fits tight spaces in the driver side of your GMC Sierra. Another option measures 8.78 inches wide. That extra fraction of an inch might not fit your specific model. Always verify your clearance. A box that is too wide will not mount properly. Precise measurements prevent installation failures and ensure you get the storage you need.

2. Verify Model Compatibility

   Your GMC Sierra year and series matter. The first VEVOR model fits the 2019-2020 GMC Sierra 1500. It does not list compatibility with heavier duty trucks. The second model is for Sierra 2500 and 3500HD owners. You need to match the box to your exact truck year and class. Buying the wrong version means it will not fit. Check the compatible truck list carefully. This ensures the mounting points align with your vehicle frame.

3. Consider Storage Length

   Length determines what you can store. The 6.6 Gal box is 28.3 inches long. The other VEVOR model is 31.5 inches long. That 3.2-inch difference allows for longer tools or gear. If you carry long items, the longer box is better. If space is tight, the shorter one may be safer. Measure your available bed space. Choose the length that fits your gear without protruding too far. This keeps your cargo secure and organized.

4. Assess Weight Capacity

   Box weight affects your truck bed load. The smaller box weighs 11 pounds. The larger one weighs 13.9 pounds. This difference is small but matters if you are near weight limits. Heavier boxes use more of your payload capacity. Lighter boxes leave room for other gear. Both are made of ABS plastic, which is durable but not weightless. Consider what else you carry. A lighter box might be better for light use.

5. Ensure Waterproof Protection

   You need to protect your tools from rain. Both VEVOR boxes are rated as waterproof. This is critical for outdoor storage. Your tools and electronics will stay dry. Check for seals and drainage if mentioned. Waterproofing keeps your gear safe from weather damage. This feature is essential for any truck box. Without it, your tools could rust or break. Ensure the product explicitly states it is waterproof before buying.
