We had a campground neighbor pulling an Airstream 22 Sport with a Tesla model x. She said her range was cut in half when towing. Also, many campgrounds would not let her charge her Tesla off the 50amp campsite circuit. They said it would damage the electrical infrastructure. Since the Tesla was only one year old, she had just agreed to trade it in on a GMC 2500 Duramax and it was just about an even trade. She was very happy.
