We can only provide lifts that attach to an existing hitch receiver. Class 3 is preferred (2” square) Outlander TM is available for class 2 (1 ¼ square) which accommodates smaller transportable scooters 100 pounds or less. These are external outside the vehicle lifts. We do not install hitch receivers or run the wiring harness from the back of the car to the battery. Check with local U-Haul or truck supply dealers for this wiring service. What we do supply is a secure and properly adjusted auto lock feature for your 3 and 4 wheel scooter or power wheelchair.
