We have only had our 2022 Model Y LR a few weeks, but have been testing it with a used Colorado Teardrop trailer, about 1,000 lb empty weight. In two different trips of about 90-135 miles with about 1,000 feet of elevation gain going one way and 1,000 coming back, we were able to get about an estimated 205 miles of full range towing this teardrop. This means that between say 20%-90% charge, the available range between charges might only be roughly 150ish miles, but that is enough to enable us to travel here in SW Colorado along several routes with superchargers. Obviously, in winter, this would likely get more difficult...we plan to test this loaded up for camping soon...more later.
