Behind the second row, with the third row folded, the 1st Gen R1S (2022–) cargo area measures about 57.8 in long, 58.9 in wide and 33.7 in high, with 51.1 in between the wheel wells. Payload is about 1,764 lb (800 kg). The front trunk is not included in these numbers.
A realistic overland load against the R1S's 800 kg (1,764 lb) payload budget — sized for an SUV cargo area.

The Algorithm Overland Kitchen Cube is a modular, aircraft-grade aluminum camp kitchen that packs down to a compact 12 × 12 × 12 in (305 mm) cube to live in your cargo area, and deploys on the tailgate.
In the Rivian R1S 1st Gen (2022–), the packed cube sits on the cargo floor behind the second row, uses only 305 mm of the 1468 mm floor length and leaves about 21.7 in (551 mm) of height above it — it fits the cargo area with room to spare.
Exact fitment specs for every bed are in the guide above. On sale now on Kickstarter until November 4.
Behind the second row, with the third row folded, the 1st-gen (2022–) measures about 1468 × 1496 × 856 mm (57.8 × 58.9 × 33.7 in) — roughly 1322 L (46.7 cu ft), with about 1298 mm (51.1 in) of floor between the wheel arches. The front trunk is not included.
About 800 kg (1,764 lb) — including passengers and accessories, not just cargo. In a three-row SUV the people use much of that, so check the door-jamb sticker.
Yes. Most 40–75 L fridges are 445–935 mm long against about 1468 mm (57.8 in) of floor, so a fridge and a second box fit end to end, and drawer systems up to about 1298 mm wide fit between the arches.
Yes, easily — the 12-inch (305 mm) packed cube leaves about 551 mm (21.7 in) of height above it.
