Interesting. I wonder if the tow capacity / range reduction relationship is linear. I plan to use the R1T to tow a
[email protected] 320 Boondock, a teardrop-style camper. Dry weight is just under 2,000 lbs, GAWR is 2,900. If things are in fact linear, that would mean the the range reduction is only about 14% at the camper's GAWR. That would be more than acceptable!
On a marginally related note, I saw a video from the LA Auto Show (Jan 2019) in which the Rivian rep stated that the truck had sufficient torque and a strong enough frame to tow much more than it;s nominal rating but was too light to safely tow more than 11k lbs.
