What Fits in a Chevrolet Silverado / GMC Sierra 1500 Bed?

The real bed dimensions, payload, and wheel-arch clearances for the Chevrolet Silverado 1500 and GMC Sierra 1500 — and exactly what overland gear you can load. Below is a to-scale 3D model of the bed, built from measured data.

The Numbers

Measured cargo-area dimensions for the T1xx · 5'8" (2019–). Every gear-fit call on this page is computed from these.

Dimensions are approximate and sourced from measured references — verify against your exact model year and trim before purchasing gear. Payload includes passengers and accessories; check your door-jamb sticker.

What Actually Fits

Payload isn't usually the limit — geometry is. Here's a realistic overland load against the T1xx · 5'8" (2019–)'s 907 kg (2,000 lb) payload budget.

Sample overland build

    The real constraint is width, not weight. The Silverado / Sierra 1500's flat floor is about 1295 mm (51.0 in) between the wheel arches and the arches rise ~215 mm (8.5 in) off the floor. Gear narrower than that stacks flat; anything wider has to sit above the arch line. That's the number that decides your build — and it's what the Kitchen Cube is engineered around.

    Built for This Bed

    Algorithm Overland Kitchen Cube — modular aluminum camp kitchen
    Algorithm Overland · Kitchen Cube

    The Kitchen Cube is a modular, aircraft-grade aluminum kitchen system engineered to live in a truck bed and deploy on the tailgate — designed around exactly the flat-floor-and-wheel-arch geometry above.

    It's built to sit on the usable floor between the arches and pack down for the trail. Fully modular, so it configures to beds like this one.

    Bed Fit FAQ

    What are the Chevrolet Silverado / GMC Sierra 1500 bed dimensions?

    The Chevrolet Silverado / GMC Sierra 1500 (T1xx · 5'8" (2019–)) measures about 1775 × 1814 × 569 mm (69.9 × 71.4 × 22.4 in), with roughly 1295 mm (51.0 in) of flat floor between the wheel arches. Figures are approximate — verify against your exact trim before buying gear.

    How much can a Chevrolet Silverado / GMC Sierra 1500 carry in the bed?

    Payload for the Chevrolet Silverado / GMC Sierra 1500 is about 907 kg (2,000 lb) — but that figure includes passengers and accessories, not just bed cargo. Budget conservatively and check the door-jamb sticker on your specific vehicle.

    Will a fridge and drawer system fit in a Silverado / Sierra 1500 bed?

    Most 40–75L overland fridges (roughly 445–935 mm long) fit ahead of the wheel wells, and drawer systems up to about 1295 mm wide fit on the flat floor between the arches. The arches rise about 215 mm (8.5 in) off the floor. Anything wider than the floor must sit above that line.
