Hi, my wife and I are looking into buying a PUP for the first time this year to go on camping trips with our three young boys (4, 3, and 1). My question relates to the towing. I have a 2015 Toyota Sienna, WITHOUT the towing package installed. I called the dealership and they said Toyota discontinued the towing package on my model and that aftermarket is my only option. I would normally be ok with this, but I have NO IDEA what I am doing when it comes to cars, especially towing packages! Any advice on how to get what I need (i.e. where to take it) and make sure I get all the important components including correct tow hitch, wiring package, engine coolant, etc? Thanks!
