Based on the window sticker it is technically impossible to tell, however with the tow package you would have self-leveling rear suspension, which comes from the factory, as opposed to the tow hitch-only which is a dealer installed option. Might need to bring it to your dealer and inquire because without a trained eye you may not be able to tell which of the rear suspension options you have.How do I tell if I have the towing package or just the towing hitch installed? Just purchased last week and noticed neither are listed on the window sticker, but definitely have the hitch and receptacle installed.
