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

Drawn to scale from measured bed dimensions.
Measured cargo-area dimensions for the DT (2019–) Crew Cab 5'7" bed. 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.
A realistic overland load against the DT Crew Cab's 907 kg (2,000 lb) payload budget.

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 truck bed, and deploys on the tailgate.

The DT (2019–) Crew Cab 5'7" bed measures about 1712 × 1687 × 546 mm (67.4 × 66.4 × 21.5 in), with roughly 1410 mm (55.5 in) of flat floor between the arches — the widest of any pickup here. The 6'4" bed is about 1938 mm (76.3 in).
About 907 kg (2,000 lb) for the DT 5'7" and 1,043 kg (2,299 lb) for the 6'4". The older DS is lower at about 690 kg (1,521 lb). Includes passengers and accessories; check the door-jamb sticker.
Very comfortably — 1410 mm (55.5 in) between the arches is wide enough for a fridge and a drawer module side by side, which no mid-size truck can do.
Yes, easily — the 12-inch (305 mm) packed cube leaves about 241 mm (9.5 in) below the bed rail. Join the waitlist for early access.
