When I was going through my delivery experience yesterday the product specialist showed me the accessory receiver (which looks to me just like a regular 2" receiver). He pointed out that I could tow up to 3500 lbs but would need the towing package to tow 5000 lbs. I did not think too much about it because I knew to tow I would need the wiring harness and connector. So today I crawled under the car and pulled off the cover and noticed the car comes with the harness and round towing connector. So I guess we can tow up to 3500 lbs without the towing kit.
