BetterWeigh weighs the vehicle and trailer, cargo, payload, tongue weight, pin weight and weight distribution. It also makes brake controller setup easy by providing the trailer brake gain needed. ENHANCED SAFETY. Whether you're loading cargo or hitching up your trailer, having an active readout of your vehicle and trailer's weight allows you to stay within safe operating limits (accurate within + / - 5%; not intended for weight certification). We bought this to use with our trailer but we sold our trailer and this never got used. I did take it out of the package and hooked it up to the car, however once we sold the trailer we had no need for it any longer.
