Charged to 100%…gonna pick up the boat and drop it in the lake. Interested to see how much the battery draws down. Lake is about 55 miles from my house, but have to grab it from winter storage location.

I believe the initial estimate that Rivian uses is that the range drops in half while towing. As you tow more with a specific trailer, it updates the estimate to what the change in efficiency really is.

How much did your range drop with your previous tow vehicle? (presumably a gas vehicle) There’s a big difference between towing a small fishing boat and a huge pontoon party boat.

When towing large trailers that have high aerodynamic drag, speed is really a factor in efficiency.

To be honest, I never paid attention because gas stations are everywhere. Definitely cut the mileage in half, but then it went back up when I dropped the boat in the water. Said the trailer was 7500 lbs, and mileage when charged at 100% would be 137.

Couple weeks ago I towed my ski boat for the first time with the R1S (PDM w/ 21" stock wheels and tires). I normally get 2.2-2.4mi/kwh just driving that route. Towing the 3500lb boat and trailer dropped it to 1.6. I think I could eek out a tiny bit more on a longer run.

1.6 sounds right unless you drive fast.

Boat towing this 5000 lb boat/trailer with my diesel truck cut mileage in half--it also cuts our R1T range in half. Our R1T with its stock 20" wheels/tires gets 1.3 mi/kWh towing this boat on our narrow, curved secondary roads at 50-55 mph. The R1T's weight, power, regeneration braking (and quiet) is a much safer/pleasant towing experience. At our steep Lake Superior ramp yesterday, the R1T retrieved the boat with no fuss. Our friends diesel truck with a similar boat really strained/slipped on their retrieve.
