I ordered my 2021 Model Y with a towing hitch for my bike rack. I decided to take it on a brief trip to my friend's house with a small, Uhaul motorcycle trailer. The lightly loaded trailer reduced my mileage by 40%, the safety hooks were very difficult to latch (tight fit in the hitch area), and I also had to unhook the trailer to supercharge. In addition, trailer mode disables autopilot/FSD. Conclusion after 300 mile RT: The Model Y kicks butt during uphill hauling - plenty of smooth power. But, stick to hauling bikes, unless you are doing some around town stuff where chargers are plentiful!
