Hummer Bed & Tonneau Covers

The Hummer is designed to stand in a league of its own—and every compatible accessory needs to match that standard. Whether you own the iconic H2 SUT or the trail-ready H3T, your truck bed features unique fitment and compatibility challenges that generic covers can't handle. RealTruck's Hummer bed covers are selected specifically for each model's unique geometry, electronics, and usage patterns.​

Each Hummer variant has its own quirks, and a cover that fits one won't necessarily fit another. The H2 SUT's slant-back cab and fold-down midgate, and the H3T's factory utility tracks all have specific clearance and mounting requirements. RealTruck carries covers built around those requirements—not adapted from another application.

The stakes are also higher on a truck like this. Drop the H2 SUT's midgate, and the bed becomes part of the cabin—soft covers won't cut it. RealTruck's hard-shell options lock down, seal tight, and hold up across both platforms without compromise.​

Why Choose RealTruck's Hummer H2 SUT or H3T Bed Covers?

No two Hummer variants share the same bed and RealTruck's lineup reflects that. The Hummer H2 SUT's slant-back cab extension and the H3T's factory utility tracks each require a different approach. RealTruck stocks purpose-built solutions for both. Where competitors offer one-size-fits-most retrofits, our covers are engineered around the particular dimensions and features of each model.​

For H2 SUT and H3T owners, the priority is integrating security and weather protection without sacrificing the factory features that make these trucks worth owning.​

• Integrated T-slot rails: MaxTrak-compatible covers support heavy-duty racks and rooftop tents above the bed while keeping the retractable cover fully operational, essential for overlanding builds.

• Ultra-compact canisters: Retractable models feature canisters approximately 7–8 in. deep, preserving maximum floor space in compact Hummer beds.

• H2 SUT hard-shell security: Slant-back hard covers follow the cab's contour and turn the 3-ft. SUT bed into a fully lockable trunk, with superior water runoff over soft alternatives.

• H3T utility rail retention: Covers like the Extang® Trifecta 2.0 include T-slot adapters that preserve the H3T's factory tie-down tracks and add full top-side weather protection.

FAQs About Our Hummer Bed Covers

Q: Will a RealTruck tonneau cover interfere with the Hummer H2 SUT’s midgate?

A: No. RealTruck's Hummer H2 SUT bed covers are engineered with the specific clearance to accommodate the SUT’s unique folding midgate and power rear window. The midgate retains functionality, allowing you to transport oversized items. ​

Q: Do I have to drill into my Hummer to route the tonneau drainage tubes?

A: No. Hummer beds include factory-installed plastic plugs that can be removed to accommodate the cover's drainage tubes directly—no drilling into the bed or frame required. ​

Q: Does the H2 SUT require a special slant-back bed cover?

A: The H2 SUT's angled cab profile means flat covers will leave a gap at the front rail. Slant-back hard-shell covers follow the cab's angle, delivering a flush, weather-tight fit that flat covers can't achieve on this truck. They also provide significantly better vertical security and water runoff than soft alternatives.
