In case anyone is interested, here is the return efficiency. The elevation indicator is wrong for some reason. I'm at around 800ft. Virtually the same for me so I'm not worried. Yea Chicago had issues for a couple of days charging cars. Last year Big Bear, CA didn't have gasoline for a week due to the enormous storm but never lost electricity. My neighbor (in Big Bear) said it was bad.
There weren't enough gas stations when cars were invented. It was a problem but horses weren't ideal either. Electrical outlets are at least an existing infrastructure. If you tow a lot for long distances, EV is not a good choice. For the amount I do it and the distances I go with it I have no issue. You can see that the Rivian now calculates the weight of the trailer automatically and refines the range as it learns the trailer and driving habits. It also doesn't run in any conserve or eco mode when towing. Without a trailer, the range on mine is about 380 miles.
