Weigh the vehicle with the trailer attached, so theGVWR or GAWR are not exceeded. If using aweight-distributing hitch, weigh the vehicle without thespring bars in place.
The best performance is obtained by correctlyspreading out the weight of the load and choosing thecorrect hitch and trailer brakes.
