Mobility equipment dealers offer scooter and hitch load wheelchair carriers designed to mount on tow hitches. Although towing hitches are designed to carry and pull items, vehicles have limitations on the load that can be applied to the hitch.

Maximum Tongue Weight is the maximum amount of weight that can be applied vertically to a tow hitch. Mobility equipment that mounts to a tow hitch applies weight vertically to the hitch. In general, the maximum tongue weight is calculated as 10% of the vehicle's towing capacity rating. The towing capacity values for Toyota vehicles are based on using a genuine Toyota towing hitch and can be found in the Toyota Owner's Manual.

Confirm the weight of the mobility equipment being installed. Ask the mobility equipment dealer for product weight information for both carrier and scooter. The total weight of the equipment should not exceed the maximum tongue weight of the vehicle.
