Required equipment and applicability

- Published maximum is for the listed, properly equipped configuration. Passengers, cargo, accessories and options can reduce the trailer mass the actual vehicle can accommodate.
- Confirm the actual vehicle trailering label, required equipment and owner-manual instructions before applying this row. Vehicle-specific payload, axle and hitch-component limits remain separate.
- DRW means dual rear wheels; unmarked drive columns in the source are the single-rear-wheel pickup columns.
Weight carrying and weight distribution
Exact installed component limits are not established by this table. Read the equipment labels and model-specific hitch instructions.
Trailer limit: Check your installed component label. Tongue limit: Check your installed component label.
No numerical installed component capacity or weight-distribution threshold inferred from the towing maximum.
Trailer limit: Check your installed component label. Tongue limit: Check your installed component label.
Weight distribution does not raise factory ratings. Axle loads and vehicle mass in the adjusted state require measurements. Receiver, ball mount, ball, and coupler must each be checked.
