Yes definitely worth getting if there's any possibility at all that you'll do any towing. The reason being if you don't get the Tow Tech Package, your 4Runner won't come with the harness for plugging in a trailer brake controller. And even dealerships can't retrofit install the OEM harness. So if you don't get the Tow Tech Package your only option will be an aftermarket trailer brake controller.Is it worth getting the tow tech package? Can you add this at the dealership?
