The real cargo dimensions, payload and clearances behind the seats of the Jeep Wrangler — and exactly what overland gear you can load. Below is a to-scale 3D model of the cargo area, built from measured data.

Drawn to scale from measured cargo dimensions.
Measured cargo-area dimensions behind the second row of the JL Unlimited 4-door (2018–). 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.
Here's a realistic overland load against the JL Unlimited's 544 kg (1,199 lb) payload budget — sized for an SUV cargo area, not a truck bed.

The Kitchen Cube is a modular, aircraft-grade aluminum camp kitchen that packs down to a compact 12-inch (305 mm) cube to live in your cargo area, and deploys on the tailgate.

Behind the second row, the JL Unlimited 4-door measures about 876 × 1054 × 870 mm (34.5 × 41.5 × 34.3 in) — roughly 897 L (31.7 cu ft). The JL 2-door is much shorter at about 610 mm (24.0 in) deep, and the older JK Unlimited about 940 mm (37.0 in). Verify against your exact trim before buying gear.
Payload for the JL Unlimited 4-door is about 544 kg (1,199 lb) — and that includes passengers and accessories, not just cargo. Wranglers have modest payload for their size, so budget conservatively and check the door-jamb sticker.
Often only sideways. Most 40–75 L overland fridges are roughly 445–935 mm long, and the JL Unlimited has about 876 mm (34.5 in) of floor behind the second row — so the larger fridges won't sit lengthways. Smaller 35–50 L units fit best, and a slide costs you more length. The cargo area is tall (~870 mm), so height is rarely the limit.
Yes. The Kitchen Cube packs down to a compact 12-inch (305 mm) cube, so it fits easily with about 565 mm (22.2 in) of height to spare above it in the JL Unlimited. Join the waitlist for early access.
