Orange County Outside MOBILITY lifts are designed to be installed onto a class 2 or class 3 hitch mounted on the back of a car, truck or van. Most of the units we recommend are attached to a hitch on the back of your vehicle. On many small compact cars this will not work. These outside lifts are the easiest to use because there is minimum exertion required from the owner. Many people choose the swing away option to swing the outside lift to the side to provide access to the back of your vehicle.
