A quality truck tool box organizes your equipment and keeps it secure. Here’s a comparison of crossover vs. chest-style toolboxes for full-size trucks.
Crossover Tool Box:
Crossover boxes mount across the bed just behind the cab. They’re the most popular style because:
- Maximum storage capacity
- Easy access from either side
- Doesn’t significantly reduce bed length for most cargo
- Compatible with most truck bed sizes
The Dee Zee DZ10170TB Red Label Crossover Box is a well-regarded example. Heavy-duty aluminum construction, reliable latch system, weather seal.
Chest-Style (Under Rail) Box:
Chest boxes mount against one side rail and don’t cross the full bed width. Good for trucks that need maximum centerline bed space.
Side Box:
Side boxes mount along one or both bed rails, low profile. Good for frequently accessed tools and equipment.
Material Comparison:
- Aluminum: Lighter, won’t rust, scratches more easily, good long-term durability
- Steel: Heavier, may rust if coating is damaged, cheaper
- Poly/Composite: Lightest, won’t rust or dent, limited structural load capacity
Sizing:
Measure your bed width before ordering. Standard full-size Silverado/Sierra beds range from 69-71" inside width. Most crossover boxes are made for 69-71" beds.
Also ensure clearance above the bed rails when the tailgate swings closed.
