Did you know that the Rivian R1T 2022 is a heavy truck? Owner’s manual says it all

By on September 25, 2021 0

It turns out that the new Rivian R1T 2022 is classified as a rugged pickup based on information published in the Rivian owner’s manual. Is everything okay or is there cause for concern? Here are all the details. Let’s take a close look at the very unique features of this truck.

Thanks to Rivian Forums for publishing the Rivian R1T Owners Manual – September 2021 edition. The current manual is approximately 178 pages long and gives an excellent overview of the features and capabilities of this truck.

Is it a Heavy Duty Pickup?

The U.S. EPA agency uses a Gross Vehicle Weight Rating (GVWR) classification to separate all vehicles into different classes with different emissions and efficiency rating requirements. The Rivian pickup truck’s GVWR is listed at 8,532 lb. This puts the R1T in the EPA Class 2b (aka. HD Pickup 3/4 ton class 8,501 – 10,000 lb).

This puts the R1T in the same classification as the Ford F-250, Chevy Silverado 2500, and Ram 2500.

What does it mean?

The world of new fully electric pickup trucks is changing the way we think about these truck classifications and capabilities. The R1T has a slightly larger footprint than a Toyota Tacoma Crew Cab and a bit smaller than a Ford F-150 Crew Cab. The R1T is equipped with a large and heavy battery to provide its 314 mile EPA range. It is also equipped with four electric motors for a total and breathtaking power of 835 hp and 908 lb-ft torque (figures according to Motor Trend).

Rivian has NOT released precise payloads or curb weights for the new R1T pickup, but the Rivian owner’s manual provides a hypothetical payload calculation with a capacity of 1,400 lbs.

The owner’s manual confirms that the R1T is designed to tow up to 11,000 lbs with a weight distribution hitch.

Why 5-lug hubs?

The Rivian R1T is equipped with 5 lug hubs. Most mid-size and half-ton pickup trucks use 6-lug hubs. The Nissan Titan XD has a GVWR of up to 8800 lbs and uses 6 lug hubs. All 3/4 ton pickup trucks in the same class 2b segment use 8-lug hubs.

Is there any concern that the R1T uses 5-lug hubs? No, not at the moment. The R1T uses a very unique 4 engine configuration. There are two electric motors mounted inside at the rear, and there are two mounted at the front. The wheels are driven by half-shafts. There are no reports of failure of these hubs or driveshafts. However, it is very unusual to see a vehicle with so much power and so much weight running on 5 lug hubs.

How does Rivian’s GVWR compare?

For reference, here are the GVWR ratings of many other popular pickup trucks.

  • Toyota Tacoma: GVWR = 5,600 lbs
  • Ford Ranger: GVWR = 6,050 lb
  • Nissan Frontier: GVWR = 6,012 lb
  • Ford F-150 Hybrid: GVWR = 7,350 lbs
  • Toyota Tundra Hybrid: GVWR = 7,660 lbs
  • Rivian R1T: GVWR = 8,532 lb
  • Nissan Titan XD: GVWR = 8,800 lb
  • Chevy Silverad 2500: GVWR = 10,850 lbs

We still do not have official information on the weight ratings of the Ford F-150 Lightning or GMC Hummer EV trucks. Lightning GVWR can be close to 8,500 lbs. The GMC Hummer EV truck’s GVWR is unknown. There is a report that the curb weight of the GMC Hummer EV Edition 1 is 9,046 lbs. This can place the GMC Hummer EV truck’s GVWR well above 10,000 lbs. The Hummer EV truck rides on 8-lug hubs.

Rivian R1T sockets

The owner’s manual states that the Rivian R1T will provide plenty of USB-c, 12-volt and 120-volt outlets throughout the vehicle. The 120 volt total output output is 1,500 watts. That’s well below the current Ford F-150 Hybrid Inverter / Generator wattage of 7,200 watts.

Rivian R1T Trailer Brake Controller

The Rivian R1T would be fitted with a 2-inch Class V receiver hitch. This hitch has a plastic cover that integrates it into the bumper. The R1T can be equipped with a 4 or 7 pin trailer wiring connection. If the trailer is equipped with electrically operated brakes, the Rivian provides a Integrated trailer brake controller. However, this is NOT a traditional controller for adjusting trailer braking gain and manual trailer brake override.

Here is how it works.

The braking gain of the trailer is adjusted using the central infotainment screen. As soon as the truck detects that a trailer (with brakes) is plugged in, it selects a towing mode and allows the driver to adjust the braking gain of the trailer. In order to test the brake actuation of the trailer, the driver can press and hold the right thumb control on the steering wheel (see image above).

It’s great to see that the Rivian R1T offers a special towing mode, integrated trailer brake controller, trailer sway control, and other features that take into account towing a trailer.


TFLtruck still does not have access to a Rivian R1T loaner vehicle for video review. We don’t know why. However, dozens of you have already offered to use your R1T or R1S vehicles for a video review. We couldn’t be more grateful.
