Heavy-Duty Storage Solutions: The Hillsboro GII Underbody Toolboxes

Truck Decks | July 24, 2025

The Hillsboro GII steel truck deck includes lockable underbody toolboxes that provide secure storage without consuming deck space. These steel boxes mount beneath the deck, keeping tools accessible while maintaining full deck surface for hauling.

Heavy-Duty Steel Construction

Steel toolbox construction handles the impact and abrasion from road debris, loading dock contact, and harsh working environments. The boxes withstand conditions that crack or dent lighter materials, protecting stored contents through years of daily use.

Lockable latches secure tools and equipment against theft during unattended periods at job sites or overnight parking. The steel construction also resists forced entry attempts better than plastic or thin aluminum alternatives.

EDPM Foam Seal Weather Protection

Complete EDPM foam sealing around door perimeters prevents moisture intrusion from rain, road spray, and pressure washing. The seal maintains effectiveness through temperature extremes and UV exposure, avoiding the deterioration common with rubber gaskets that dry out and crack.

Moisture-free storage protects tools from rust and corrosion, particularly important for precision equipment and power tools that suffer damage from repeated wet-dry cycles.

Size-Matched Configuration

Multiple toolbox widths accommodate different truck bed and chassis configurations:

18-Inch Width

Fits short box single rear wheel beds, providing compact storage without interference with wheel wells or frame components.

30-Inch Width

Designed for long box single rear wheel applications, maximizing storage capacity while maintaining proper clearance for suspension travel and body components.

30-Inch Tapered Width

Configured for long box dually beds, the tapered design clears wider rear wheel spacing while providing substantial storage volume.

36-Inch Tapered Width

Sized for 60-inch and 84-inch cab-to-axle chassis, these larger boxes accommodate the additional underbody space available on extended wheelbase configurations.

Maximizing Deck Functionality

Underbody mounting positions storage where it doesn’t compete with deck hauling capacity. The full deck surface remains available for equipment, materials, and cargo while tools stay organized and protected underneath.

This arrangement proves particularly valuable for operations that regularly haul full deck loads but need immediate tool access without unloading cargo.

Maintaining Ground Clearance

Toolbox mounting considers ground clearance requirements for off-road access and unimproved site navigation. Proper installation positions boxes to avoid contact with terrain while maximizing storage volume.

The boxes integrate with the deck’s overall design, maintaining approach and departure angles that prevent dragging on uneven ground or steep transitions.

Steel Deck Storage Integration

The underbody toolboxes complement the GII’s steel deck surface, providing the complete package for operations prioritizing durability over weight savings. Both deck and storage handle demanding environments involving heavy equipment, abrasive materials, and harsh conditions.

The toolboxes share the GII’s premium PPG HD epoxy paint system, maintaining corrosion protection across all exposed surfaces.
