You have to remember that 2,000-lb tow capacity has to include not only the trailer, but all cargo in the trailer, all cargo in your Sorrento, and the passengers in the Sorrento. In my opinion, you will be severely overloaded. You probably need to think about a 1,000-lb trailer or a larger tow-capacity vehicle. With only 2,000-lb tow capacity, it is obvious your TV does not have a towing package. Without that actually, I would not tow anything at all. I believe the Sorentoís that have a tow package are around 3,500 to 5,000 lb tow capacity and all wheel drive for more robust rear axle. That is what you need for towing. Not sure you can aftermarket a tow package and hit that 5,000 lb number.
