If you could have the dealer install the tow package it would be very expensive. It requires changing the ring gear and pinion, adding the auto leveling hardware and control circuitry, changing the BCM, replacing the instrument cluster and other items. It would be cheaper to trade the vehicle in for one with the tow package, which is installed at the factory.
If you aren't sure if you have the tow package, look for the compressor. It is located behind the rear axle, on the left side. It has a flexible rubber shield on it, and has air lines running to the air shocks.
