I understand your logic. But using the paddles you can keep the car in the optimum gear without heating up the DSG clutch pack that (very basically) serves the same purpose as a torque converter. But you need to be careful about weights. Assuming 4WD you don't need to worry too much about the caravan club's 85% advisory limit, but you do need the caravan MTPLN be well within the Yeti's towing limit which is between 1800kg and 2100kg depending on drivetrain.
