Q: Do I need to modify my Model S to install the EcoHitch?
A: The EcoHitch bolts directly to the car with no drilling or welding required. Trimming an access port in the plastic at the base of the bumper for the trailer hitch receiver is required to achieve the sleek, hidden design. Doing this ensures the trailer hitch crosstube is totally hidden behind the bumper instead of hanging below the bumper – which is why you would get this trailer hitch in the first place.
