Ford adds Onboard Scales and Smart Hitch To 2021 F-150 Onboard Scales will help accurately estimate cargo weight and indicate capacity. Smart Hitch measures tongue weight to help customers properly hitch up and reduce sway for safer towing. Advertisement “I don’t need help hitching up my truck” or “A real truck owner doesn’t need all this technology.” These are the comments I’m ready to hear about the latest truck technology from Ford. And while it may apply to many F-150 customers, others may need or want a truck, but feel intimidated by towing or trailering. Heck, watch any boat dock during a busy Saturday and you can see, not all truck owners have the same level of confidence.
