Best Rivian R1T Bed & Cargo Accessories of 2026

The best Rivian R1T bed accessory is the LASFIT R1T 4.5 ft Bed Mat, a TPE liner cut for the truck bed across 2022 through 2026 vehicles without a drop-in liner already fitted. Front trunk gear is the part owners get wrong, because Rivian split the R1 into Gen 1 and Gen 2 and the frunk liners are not interchangeable. Below we compare R1T cargo picks on fitment scope, install effort, and which zone of the truck each one serves.

LASFIT Rivian R1T 4.5 ft Bed Mat
#1 · Best OverallLASFIT

LASFIT Rivian R1T 4.5 ft Bed Mat

Best for protecting the 4.5 ft pickup bed

A raised-edge TPE mat cut for the R1T 4.5 ft bed, listed for 2022 through 2026. The listing excludes trucks that already have a drop-in bed liner, so this is the pick for a bare bed — the most common R1T configuration.

Rivian R1 Cargo Crossbars
#2 · Best for External CargoRivian

Rivian R1 Cargo Crossbars

Best for roof or bed cargo systems

Factory Rivian cargo crossbars supplied as a pair. Because crossbars serve more than one mounting position on an R1, confirm the intended position and follow current Rivian load limits for that position and the accessory on top of it.

Rivian R1 Gen 2 Frunk Mat
#3 · Best Gen 2 Frunk LinerBestEvMod

Rivian R1 Gen 2 Frunk Mat

Best for second-generation front trunks

TPE liner shaped for the Gen 2 front trunk, model years 2025 and 2026 only. Its listing is explicit that it is not for a 2022 through 2024 frunk — this is the clearest generation lock in the R1 catalog.

Rivian R1 Frunk Cooler Organizer
#4 · Best Gen 1 Frunk OrganizerBestEvMod

Rivian R1 Frunk Cooler Organizer

Best for 2022-2024 frunk storage

An insulated, three-compartment organizer with a leak-resistant cooler lining, listed for 2022 through 2024 R1 vehicles. It makes the Gen 1 frunk a genuine grocery and drinks space rather than an awkward second trunk.

Frequently Asked Questions

What is the best bed mat for a Rivian R1T?

The LASFIT Rivian R1T 4.5 ft Bed Mat is the best pick. It is raised-edge TPE cut for the R1T 4.5 ft bed across model years 2022 through 2026, and it lifts out to be hosed clean. Its listing excludes trucks that already have a drop-in bed liner fitted.

Do Rivian R1S cargo liners fit the R1T bed?

No. The R1S all-weather cargo liner is shaped for the SUV enclosed rear trunk floor, and its own listing states it is not presented for the R1T bed. A pickup bed and an SUV cargo well are different surfaces with different walls and drainage.

Which frunk liner fits my Rivian R1T?

It depends on the build year, not the model. The frunk cooler organizer is listed for 2022 through 2024 Gen 1 vehicles, and the Gen 2 frunk mat for 2025 and 2026 vehicles only. Check the model year on your door jamb label rather than the year you took delivery.

How much weight can Rivian R1 cargo crossbars carry?

Use the limit Rivian publishes for your vehicle, the specific mounting position, and the accessory combination you are installing. The rating belongs to the installed stack rather than the bars alone, so subtract the weight of any carrier or basket from the limit before loading cargo.
