Bed, tongue weight, and wheelbase
The trailer rating is one limit. The bed has to fit the load, the tongue or pin has to fit in payload, and the wheelbase is the column the chart uses.
- An illustrative 10 percent of the 20,000 lb conventional maximum is 2,000 lb of tongue weight. This is not a measured load or recommended percentage; actual load may be higher.
