I have had no issues. While stopping at stop lights or waiting to enter the highway I usually keep my foot on the brake, as I would when driving without a trailer in tow. Of course if I were stopped for a long period of time, I would put the tv in park. I don't think you will have any problems as long you don't ride the brake while moving. I am sure you will have people chime in with more tow time than I have. I don't drive any different while towing than without a tt, I just go slower and watch my turns, and try to plan my lane changes in advance.
