Among electric trucks, the Rivian R1T cargo space dimensions are what set it apart. It’s not the biggest bed in the class, but between the clever frunk, Gear Tunnel, under‑bed bin and hidden interior storage, this truck plays Tetris with your stuff better than most full‑sizes.

Specs vs reality
Rivian R1T bed dimensions and setup
Let’s start with the bed, because that’s where everyone gets stuck on the spec sheet. On paper, a 4.5‑foot bed sounds small next to a full‑size half‑ton. In practice, the R1T bed is short but deeply thought out.
Rivian R1T bed dimensions
Key bed measurements for planning plywood sheets, bikes, and overland setups.
| Measurement | Imperial | Metric | Notes | ||||
|---|---|---|---|---|---|---|---|
| Bed length (tailgate up) | 54.1 in | 1373 mm | "Bed length at rail" | ||||
| Bed length (tailgate down) | 83.8–83.9 in | ~2130 mm | Load‑bearing panel bridges the gap | ||||
| Bed width at floor | 51.1 in | 1299 mm | Between bed walls | ||||
| Width between wheelhouses | ~50.2–50.3 in | ~1277–1278 mm | Still fits 48 in plywood snugly | ||||
| Bed height (tonneau open) | 18.3 in | 465 mm | From floor to rail | Max cargo height (tonneau closed) | 17.1 in | 434 mm | Height of weather‑sealed trunk |
| Bed volume (open) | 29.2 cu ft | 828 L | Without tonneau closed |
Dimensions are approximate and may vary slightly by model year and options.
Yes, it’ll haul 4x8 sheets
The tailgate uses an articulated hinge, so when you fold it down you get more than just the tailgate’s height in extra floor length. That’s how Rivian gets to roughly 83.5–83.9 inches of usable bed floor. With the optional power tonneau or the manual cover, the R1T bed becomes a giant, weather‑sealed trunk. You give up a bit of height, roughly an inch compared with bed rail height, but gain the ability to leave tools, luggage or camera gear locked and out of sight without resorting to a shell.
Best uses for the R1T bed
- Building supplies: 4x8 sheets, lumber up to about 7 ft before it overhangs.
- Outdoor toys: bikes, kayaks, coolers and camp boxes.
- Dirty gear: things you don’t want inside the cabin or Gear Tunnel.
Things to keep in mind
- Height under tonneau: tall coolers and cargo crates may need the cover open.
- Spare tire vs cooler bin: models with a spare use most of the under‑bed space.
- Bed camera: handy for watching straps and soft cargo at highway speed.
R1T frunk dimensions and what actually fits
The R1T’s frunk isn’t the cavernous front trunk you’ll find in some big‑nose SUVs, but it’s more than a party trick. Rivian quotes about 11–11.1 cubic feet of space, split across an upper and lower level.
Rivian R1T frunk dimensions
Approximate dimensions of the bilevel frunk.
| Measurement | Imperial | Notes |
|---|---|---|
| Length | 25.4 in | Front to back at floor |
| Width | 54.8 in | Side to side at widest point |
| Depth | 22.7 in | Floor to top opening |
| Volume | ~11–11.1 cu ft | Upper + lower section combined |
Measured values vary by source; treat these as working estimates.
Practically speaking, that means you can treat the frunk like the cargo hold of a mid‑size crossover:
- Two carry‑on roller suitcases plus a few soft duffel bags
- A week’s worth of groceries for a family of four
- Camping stove, propane bottles and food bins
- Helmet bags, climbing gear, or camera cases you’d rather not leave in the open bed
Built‑in cooler mode
Gear Tunnel dimensions: the R1T’s secret weapon
If the R1T has a party piece, it’s the Gear Tunnel, a horizontal storage tube running between the cab and the bed. It’s that weird silhouette cut‑out you see just ahead of the rear wheels; once you’ve lived with it, you’ll never want a conventional truck again.
Rivian R1T Gear Tunnel dimensions
Approximate storage size for the Gear Tunnel.
| Measurement | Imperial | Metric | Notes |
|---|---|---|---|
| Length | 65 in | 1651 mm | Door to door across the truck |
| Height | ~16–18 in | ~406–457 mm | Varies slightly along opening |
| Depth | ~18–20 in | ~457–508 mm | Opening to back wall |
| Volume | ~11.7 cu ft | ~331 L | Weather‑sealed, washable space |
Rivian quotes about 11.7 cubic feet of volume for the Gear Tunnel.
What fits in the Gear Tunnel
- Skis and snowboards (up to ~200 cm, diagonal).
- Two folding camp chairs plus a compact table.
- Golf bags laid diagonally.
- Muddy boots, waders and fishing tackle.
- Portable grill and charcoal.
Why it matters
- Weather‑sealed: Great for valuables you don’t want in the open bed.
- Washable: Hose out mud and sand; it’s the truck’s built‑in mudroom.
- Power nearby: 110V and 12V outlets at the tunnel ends for fridges or compressors.
The tunnel trick
Under‑bed bin and rear‑seat storage
Under the R1T’s bed, where a gas truck would hide a muffler, Rivian carved out a lockable, weather‑tight storage bin. Depending on spec, this space either houses the spare tire or becomes a giant cooler‑slash‑stash box.
Under‑bed and rear‑seat storage details
Hidden storage spaces that don’t show up on the usual spec sheet.
| Area | Approx. Volume | Best for | Notes |
|---|---|---|---|
| Under‑bed bin | ~7 cu ft (up to 200 L) | Full‑size spare or ice‑filled cooler | Bin has a drain plug for easy cleaning |
| Under‑rear‑seat bin | 2.1 cu ft max | Straps, recovery gear, small tools | Available on models with the storage bin option |
| Bed side pockets | Small | Tie‑downs, gloves, nozzle for compressor | Molded into the bed walls |
Exact volumes vary with options like the spare tire.
Cooler vs spare tire
Interior cargo space: seats and small‑item storage
Inside, the R1T is more SUV than work truck. Officially, the cabin offers around 23 cubic feet of cargo volume with all seats in place, but what matters more is how that room is carved up.
Where the small stuff goes
Thoughtful interior storage keeps the bed free for big cargo.
Flip‑forward rear seat bases
Under‑floor rear storage
Center console & door pockets
Add the front and rear cubbies together and you end up with a cabin that behaves like a compact SUV with a pickup truck grafted onto the back. For families, that means you can keep food, electronics and kid gear inside while the wet, sandy and sharp stuff lives in the bed, Tunnel or under‑bed bin.
How the R1T’s cargo space compares to other EV trucks
Versus full‑size EV trucks
Compared with a Ford F‑150 Lightning, GMC Hummer EV or Chevy Silverado EV, the R1T’s bed is shorter. Those trucks offer beds closer to 5.5 or 6.5 feet.
But they don’t match the R1T’s combination of a sizable frunk, the Gear Tunnel, and the under‑bed bin. If you care more about secure, weather‑sealed storage than raw sheet‑rock volume, the R1T punches above its size.
Versus mid‑size gas trucks
Dimensionally, the R1T is between a Toyota Tacoma and a full‑size half‑ton. The 4.5‑foot bed is roughly on par with a mid‑size crew cab’s short box, but the frunk + Tunnel combo has no real rival.
If you’re coming out of a Tacoma or Colorado, you’ll lose very little in open‑bed capacity and gain a surprising amount of lockable volume.
The tradeoff in one sentence
Real‑world packing scenarios
Specs are helpful, but what most shoppers want to know is simple: Can this truck actually carry my life? Let’s run through a few realistic use cases.
Will it fit? Common R1T cargo scenarios
Weekend camping for four
Put tents, sleeping bags and bulky duffels in the bed under the tonneau. Use the Gear Tunnel for chairs, a folding table and camp stove. Keep food and a small cooler in the frunk so bears don’t window‑shop your glass roof.
Home‑improvement run
Stack 4x8 plywood or drywall sheets flat in the bed with the tailgate down; strap them to the bed cleats. Smaller items like paint cans, hardware and tools can live in the frunk or under‑bed bin so they don’t tip over.
Bike weekend
Two or three mountain bikes can go in the bed (front wheels over the tailgate) or on a hitch rack. Helmets, shoes and packs slide into the Gear Tunnel. Muddy pads and gloves go in the under‑bed bin where they can drip dry.
Airport pickup duty
Suitcases and golf bags can go in the frunk and Gear Tunnel, leaving the bed empty or ready for oversize oddities. Passengers will appreciate that their luggage isn’t sitting in plain view.
Snow‑day ski trip
Skis and poles ride safely in the Gear Tunnel; boots and outerwear get the rear seat and floor. The bed is free for snowboards, sleds and that never‑ending pile of kids’ gear.
Pay attention to payload
Buying a used Rivian R1T: cargo‑space checklist
Shopping used for an R1T? Cargo space is about more than dimensions; it’s about condition and configuration. A truck that’s spent three years hauling kayaks will age differently than one that’s hauled gravel.
Used R1T cargo and storage inspection
1. Inspect the bed and tonneau
Look for deep gouges, bent tie‑downs and damage to the bed floor or side rails. Cycle the power tonneau (if equipped) several times; listen for binding, and check that it seals evenly against the rails.
2. Open the under‑bed bin
Lift the bed panel and check for corrosion, lingering odor or damage from using it as a cooler. Verify the drain plug is present and that any spare tire or tools are correctly secured.
3. Check the Gear Tunnel doors
Open both Gear Tunnel doors and sit or stand on them gently. They should feel solid, latch securely and seal against water. Look for cracks in the plastic liners or obvious signs of a hard impact.
4. Evaluate the frunk
Open the frunk and remove the lower panel. Check for moisture, stains, and damage around the drain plug. Make sure the power struts lift smoothly and the latch closes confidently.
5. Look for water leaks
Inspect carpets and cubbies in the rear seat area, under‑floor cargo bins and Gear Tunnel for signs of past water intrusion. EVs don’t like standing water anywhere it’s not designed to be.
6. Confirm accessories and mats
Cargo liners, bed mats and bin mats add value and often signal a careful owner. Missing covers, loose trim or broken organizers can become negotiation points on price.
