I tow with the Ford Triton V-10 engine, but do not have the Tow/Haul mode selector. I tow my Corolla on a dolly and I don't even know that it is behind me, with the exception of the higher passes in Colorado. Without the camera to see it I wouldn't know it was there. I have towed it cross country with only one problem. That was a blowout on the dolly with new tires. I did not know that the tire had blown until I saw smoke in the mirror. Backing it up, like earlier post said disconnect the car or the wheels on the dolly will start to turn.
