We would like to add a hitch to tow a camper (3,000 lb empty-less than 3500 lb packed). We found several brochures that state the tow prep package comes standard on all 2016 Sienna models. However, our dealership looked up our vehicle specifications from our VIN number and said it didn't look like we had the prep package. We called Toyota directly and they stated that the tow prep package is standard. We are confused and do not want to tow if it will potentially cause issues with the vehicle but it sounds like it should be fine. Any thoughts? Anyone have experience with this? Thanks!!!
